How to Create Multiple GPIO Pwm Waveforms That Are in Sync Using Pigpio for Trapezoidal Motor Contro

Don't expect much from this answer, you are veering into a more esoteric region of pigpio.I suggest you look through the wave examples at pigpio examples. In particular Wave PWM 2 may be helpful.

I think you can probably achieve what you want but it will need some experimentation on your part.If you haven't got a 'scope also consider slowing the waveforms down and checking the logic with piscope

What is used to control AC motor speed?

For an AC motor, you can reduce the voltage to reduce the speed. As a quick hack, you could try running it off 120 V AC; if that speed is good, you're done.Otherwise, you could try a triac, which chops the voltage for part of each AC cycle, making the average voltage lower, or you could use a variable transformer, like this:electroniccity.

Furnace Blower Motor Replacement

I would replace the motor with a 4 speed PSC motor. Psc motors have more starting torque than non PSC motors and use less electricity to run and start, because they are more efficient. These motors are usually 4 speed however a few are 3 speed. you may want to check the capacitor since the motor will not run if the capacitor is bad and capacitors cost a lot less than a motor

PWM npn sinking signal

Page 208 shows the block diagram of a typical I/O port.The PWM peripheral communicates with the output drivers via the output multiplexers. Therefore the sink/source capabilities in PWM mode are the same as when they're in GPIO mode, which for this device is either 15mA or 20mA.

Pulse width of a stepper driver

If you increase your pulse frequency (and this is what you do when you decrease your HIGH time*), you increase speed.

And increasing speed means decreasing torque.

Generally, using microstepping can help to reduce vibrations. See also this discussion.

We have adjusted the review and score accordingly. As an example of the truism that specs do not always matter, the Droid 3 is it. On paper, this heir to Verizon's Motorola Droid line ($200 with a new 2-year contract as of 7/15/2011) sounded extremely promising: It has a dual-core processor, a 960-by-540-pixel qHD display, and a full QWERTY slide-out keyboard (complete with number row). The specs were enough to have me ready to dump my trusty old Droid Incredible and pick up one of these bad boys. But after spending some time with the phone, I think I will be holding onto my Droid Incredible a little longer. Something I've always like about the Motorola Droid series was the build quality, and the Droid 3 feels extremely well built. At 6.49 ounces, the phone is heavier than either the Droid or the Droid 2, though it's balanced enough that you might not notice the extra weight while holding it. Much of the phone's outer case is composed of a soft plastic that feels pleasant to hold in your hand. The top sliding portion is made of steel, and the sliding mechanism is quite smooth. When upright, the Droid 3 stands slightly taller than its forebears (at 4.9 inches), though it's not much thicker than the original Droid. Unlike previous versions, the Droid 3 features an additional number row in its full QWERTY keyboard. I found it easy to pound out longer text and email messages, though the keyboard can feel a little clicky at times. Regardless, it is a vast improvement over the keyboards on the Droid and Droid 2. Though the Droid 3 has a 4-inch qHD (540-by-960-pixel) display, images and text did not look any better than they did on the original Droid. Icons are not particularly sharp, and you can easily see a grid of dots on the screen. Sadly, the Droid 3 lacks the physical camera button of its predecessors, so you will be stuck using the touchscreen shutter button to take your photos. The Droid 3 ships with the latest version of Gingerbread (Android 2.3.4). It runs the same version of MotoBlur that we saw on the Droid X2, so it's not as bulky as other overlays (such as what we've seen on Samsung or HTC devices). You get five home screens to play with, a handful of widgets, and a customizable dock with this version of MotoBlur, as well as the ability to sort apps in the app drawer by how frequently they are used. Speaking of apps, the Droid 3 comes with a considerable number of bloatware apps preinstalled. While some of them are useful (such as the Kindle app or GoToMeeting), it's frustrating to know that you can not uninstall things like City ID or NFL Mobile. Luckily, the two game demos (Let's Play Golf and NOVA HD) can be removed, but that Slacker app will forever be stuck on your phone taking up precious application storage space (of which you get only 2GB). The Droid 3 does not come preloaded with the latest version of the Android Market, though it will most likely receive it in the next few weeks. The Droid 3 packs a 1GHz dual-core Texas Instruments OMAP processor that makes the phone feel speedy when browsing through menus or scrolling through the home screens. Games ran smoothly, and the phone was quite responsive when tapping around the screen. My review model of the Droid 3 seemed to have reception issues. One second, I would have full bars; the next, I would barely have any 3G coverage. Loading webpages became a race to see if I could get a page open before my signal dropped and my data speeds slowed to a crawl. Meanwhile, my HTC Droid Incredible maintained its signal strength while using it in the same location. Call quality on the Droid 3 also had its share of problems. The people I called from our San Francisco offices told me that I sounded muffled, almost as if there was a cloth over my mouth and the phone. The phone also does a poor job at filtering out background noises. Unlike the upcoming Droid Bionic, the Droid 3 lacks LTE support. That said, it is a world phone (it comes with a preinstalled SIM card), and most of the LTE phones we have seen thus far have suffered from terrible battery life. The Droid 3's battery life is still an issue though; I managed to drop the battery from an 80 percent charge down to only 30 percent in 2 hours of moderate use. Motorola is not known for its great phone cameras, and the Droid 3 is no exception. Images taken on the 8-megapixel camera came out dark, and all had a blue tint to them. At first I thought the phone's screen was to blame, but the issue persisted when I viewed the photos on my PC's screen. The Droid 3 can shoot 1080p video, but videos also suffered from the blue coloring that plagued photos. Even after tweaking the settings, photos still retained that blue look to them. Surprisingly, I have the impression that the camera on the original Droid took sharper images than the new Droid 3's camera did in our casual tests. The 0.3-megapixel front-facing camera has better white balance than the rear-facing one, but none of the preinstalled software on the phone took advantage of it. This Droid 3 had no video calling apps, and the stock Google Talk app did not support video chatting. The Droid 3 is DLNA-certified, so you can stream photos, music, and videos to and from any other DLNA-compatible devices you own. The Droid 3 comes with an HDMI-out port so you can share your photos and videos with everyone on a larger HDTV. The Droid 3 uses the standard bare-bones Android audio player app, and music playback is average. It should be noted that the Droid 3 does not ship with a microSD card, though you can always add one later. The Motorola Droid 3 is a disappointment. On paper, Motorola seems to have done everything right: The company put in a fast processor, a high-resolution display, and a great keyboard, and it even loaded the phone with Gingerbread. But when it came time to deliver, it really dropped the ball. I understand that not everyone cares about bloatware, and not everyone uses their phone to take pictures, but I expected more from Motorola. The screen lacks sharpness, the call quality is subpar, and the phone has reception problems. The keyboard is great, but even that cannot save a phone that has so many other issues and quirks. I am sincerely hoping that Motorola learns from these bugs and fixes them before it ships the Bionic next month. As someone who was looking forward to upgrading my phone to the Motorola Droid 3, I think I will be saving my money and waiting to see what else is coming further down the line. I suggest that you do the same.
Basic Structure and Working Principle of Stepping Motor
Basic Structure and Working Principle of Stepping Motor
Basic structure and working principle1. Basic structure of stepping motor (as shown in Figure 1)Fig. 1 basic structure of stepping motor2. Working principleAccording to the external control pulse and direction signal, the stepper motor driver controls the winding of the stepper motor to be energized in the forward or reverse direction in a certain sequence through its internal logic circuit, so as to make the motor rotate in the forward / reverse direction or lock.Take the 1.8 degree two-phase stepping motor as an example: when the two-phase windings are energized, the motor output shaft will be stationary and locked. The maximum torque to keep the motor locked at rated current is the holding torque. If the current of one phase winding changes direction, the motor will rotate one step (1.8 degrees) in a given direction.Similarly, if the current of another winding changes direction, the motor will rotate one step (1.8 degrees) in the opposite direction to the former. When the current passing through the coil winding changes to excitation in sequence, the motor will realize continuous rotation step along the established direction, and the operation accuracy is very high. For 1.8 degree two-phase stepping motor, 200 steps are required to rotate one cycle.Two phase stepping motor has two winding forms: bipolar and unipolar.There is only one winding coil on each phase of bipolar motor. When the motor rotates continuously, the current should be changed to excitation in the same coil in turn. In the design of driving circuit, eight electronic switches are required for sequential switching. Unipolar motor has two winding coils with opposite polarity on each phase. When the motor rotates continuously, it only needs to energize and excite the two winding coils on the same phase alternately.Only four electronic switches are needed in the design of the driving circuit. In the bipolar drive mode, because the winding coil of each phase is 100% excited, the output torque of the motor in the bipolar drive mode is about 40% higher than that in the unipolar drive mode.Characteristics of stepping motor1. Precise position controlThe rotation angle of the shaft is determined according to the number of input pulses. The position error is very small (less than 1 / 10 degree) and does not accumulate.2. Precise speedThe speed of stepping motor depends on the frequency of input electric pulse, which can be accurately controlled and easily adjusted. Therefore, it is widely used in various motion control fields.3. Forward / reverse rotation, emergency stop and locking functionThe effective control of motor torque and position, including static torque, can be realized in the whole speed range. When the motor is locked (there is current in the motor winding and there is no external pulse command input for rotation), a certain torque output is still maintained.4. Precise position control at low speedWithout the adjustment of the gearbox, the stepping motor can run smoothly at very low speed and output large torque, which avoids power loss and angular position deviation, reduces cost and saves space.5. Longer service lifeThe brushless design of stepping motor ensures the long service life of the motor. The life of stepping motor usually depends on the bearing.Vibration and noiseGenerally speaking, under no-load operation of stepping motor, resonance will occur when the operating frequency of motor is close to or equal to the natural frequency of motor rotor, and serious out of step phenomenon will occur.There are several solutions to the resonance problem:A. Avoid vibration zoneSo that the working frequency of the motor does not fall within the vibration range.B. Driving mode with subdivisionThe micro step driving mode is used to subdivide the original one step into multi-step operation, so as to improve the resolution of each step of the motor and reduce the vibration. This can be achieved by adjusting the phase current ratio of the motor. Micro step does not increase the accuracy of step angle, but it can make the motor run more smoothly and have less noise. Generally, when the motor runs in half step, the torque will be 15% less than that in the whole step, while when the sine wave current control is adopted, the torque will be reduced by 30%.SummaryIn mechanical design, we often use stepper motor. For example, stepper motor drives synchronous belt shaft to realize linear motion; For another example, using a stepping motor to drive the ball screw shaft can also convert the rotary motion into linear motion. Because there is no need for feedback system, the biggest advantage of stepping motor is economic and practical, and good accuracy can be obtained. In fact, in addition to the motion platform in the machine, stepping motors can also be found in life, such as printers, scanners, cameras, ATM machines, 3D printers and so on.Disclaimer: This article is reproduced online and the copyright belongs to the original author.

Such drives are therefore generally less efficient than AC/DC-AC conversion based drives. The motor develops the torque required by the load and operates at full speed. The output shaft transmits the same torque to the load, but turns at a slower speed. Since power is proportional to torque multiplied by speed, the input power is proportional to motor speed times operating torque while the output power is output speed times operating torque. The difference between the motor speed and the output speed is called the slip speed. Power proportional to the slip speed times operating torque is dissipated as heat in the clutch. While it has been surpassed by the variable-frequency drive in most variable-speed applications, the eddy current clutch is still often used to couple motors to high-inertia loads that are frequently stopped and started, such as stamping presses, conveyors, hoisting machinery, and some larger machine tools, allowing gradual starting, with less maintenance than a mechanical clutch or hydraulic transmission.— — — — — —Motor promoterLawson saw great opportunities in the creation of a motor car industry in Britain, and sought to enrich himself by garnering important patents and shell companies. In 1895, as one of many attempts to promote his schemes and lobby Parliament for the elimination of the Red Flag Act, Lawson and Frederick Simms founded the Motor Car Club of Britain. Lawson and the Motor Car Club organised the first London to Brighton car run, the "Emancipation Run", which was held on 14 November 1896 to celebrate the relaxation of the Red Flag Act, which eased the way for the start of the development of the British motor industry. Lawson attempted to monopolise the British automobile industry through the acquisition of foreign patents. He acquired exclusive British rights to manufacture De Dion-Bouton and Bollée vehicles. He founded a succession of promotional companies including: The British Motor Syndicate — not to be confused with British Automobile Commercial Syndicate Limited. BMS was the first of many of Lawson's schemes to collapse in 1897. Lawson also founded British Motor Company, British Motor Traction Company, The Great Horseless Carriage Company, Motor Manufacturing Company, and with E. J. Pennington forming Anglo-American Rapid Vehicle Company. With his one great success, The Daimler Motor Company Limited, he bought in the rights of Gottlieb Daimler though this company too was to be reorganised in 1904.

In 1917 28,000 cars were made making it the seventh largest car maker in the United States. The first car was a 2-seat runabout with 2-speed transmission and a 4-cylinder engine made by Ferro. 7000 were made in the first year of production. Electric lighting was added as a standard fitting in 1915. A six-cylinder car was added to the range in 1915 followed in 1917 by a Sedan. From 1918 the company got into financial problems and the 4-cylinder models were dropped from the range and the Sedan went as well in 1919. In 1920 a new model, the Duplex, powered by an overhead-valve, four-cylinder engine joined the six-cylinder model and a sedan body rejoined the range. The six-cylinder cars were no longer listed after 1921 and production had fallen to 2100 cars. The company moved to Ypsilanti, Michigan, where the cars were made in the Ace car plant, but this could not save the company and the last cars, probably made in 1922, were sold in 1923.

Design Considerations of High Voltage Motor Control System
Design Considerations of High Voltage Motor Control System
Design considerations of high voltage motor control systemIn modern robot design, any movement of head, neck and limbs needs the support of a variety of motors, such as traditional rotating motor, stepping motor, linear motor and other special motors, but the driving and control requirements of these motors are different. How to realize the accurate control solution of each motor? How to control them with the lowest power consumption? It is often a big challenge for designers. This paper will discuss in detail what problems should be paid attention to in the implementation of each core subsystem of high voltage motor control system.High voltage alternating current (HVAC) motors, industrial inverters or high voltage permanent magnet brushless motors are several examples of high voltage systems, which are typically classified according to their horsepower. Although it is still the most common, other types of motors have also appeared, such as linear motor and gear head motor with embedded various actuators. Digital motor control solutions allow precise control of the position, speed and torque of these mechanical drive mechanisms. MOSFETs in such large mechanical drive mechanisms usually have a capacity of more than 600V.For example, Ti has a gate drive solution tps2829, an in-phase high-speed MOSFET Driver. When combined with the tlv3501 comparator in the feedback loop, the gates in these systems can be digitally controlled. In addition, TI's MOSFET Driver (such as ucc37321 or ucc37323) can directly drive small motors or power devices, such as MOSFET or IGBT.Main design considerations of high voltage motor control systemThe core subsystems of high voltage motor control system include controller, isolation, controller interface and motion feedback.Controller: Ti also provides a series of control processor solutions, from ultra-low power MSP430 microcontroller to tms470 ARM7 based processor and C2000 digital signal controller (DSC). Appropriate controller can optimize motor drive efficiency, improve reliability and reduce overall system cost. The 32-bit DSP level performance of C2000 controller and on-chip peripherals optimized for motor control enable users to easily realize advanced algorithms, such as sensorless vector control of three-phase motor. C2000 series controllers (from low-cost f28016 to the industry's first floating-point DSC TMS320F28335) are software compatible.Isolation: ti's digital isolator has logic input and output buffers, which are isolated by silica to provide 4KV isolation capacity. When combined with isolated power supply, these devices can block high voltage, isolate ground, prevent noise current from entering local ground, and interfere with or damage sensitive circuits.Controller interface: RS-232 or RS-422 is sufficient for many systems. RS-485 signaling may be bundled with some protocols, such as PROFIBUS, INTERBUS, MODBUS or BACnet, each for the specific needs of end users. Sometimes, controller area network (can) or Ethernet / IP (Industrial Protocol) is preferred to meet networking requirements. M-lvds is an alternative that can provide lower power consumption.Motion feedback using external circuits: the isolated delta sigma modulator (amc1203 / amc1210) is very suitable for shunt measurement to flatten burrs and increase current feedback resolution. In addition, ina19x (x = 3 to 8) and ina20x (x = 1 to 9) provide a wide common mode voltage for low-end and high-end current shunt monitoring.Hall effect or magnetic sensors are usually more efficient when measuring currents exceeding 10a, and they can inherently provide isolation. Ads1204, ads1205 and ADS1208 are three recommended devices. In order to connect ± 10V (20vpp) signal to ADC with 3.3V or 5V power supply, an ina159 level difference amplifier can be used. ADCs like ads7861 / ads7864 or ads8361 / ADS8364 can provide 4-channel or 6-channel simultaneous current sampling.

Also, you can put in whatever you want. Fruits - bananas and strawberries - are great, or grated chocolate. You will need: 250g each flour, margarine, sugar 4 eggs 1 tsp each vanilla essence and baking powder Beat the margarine and sugar until it's fluffy-ish. Add the eggs. Pour in the flour and vanilla and baking powder. Bake in a greased baking tin for 20-30 minutes. You can put absolutely anything in this - banana is good, or with finely grated zucchini (yes, zucchini, the vegetable) and three tablespoons of cocoa powder. I would recommend some raspberries if you like those - defrost a bag of frozen ones - make two cakes, slather jam and buttercream icing (use icing sugar and melted butter) between, dust icing sugar lightly on top, and you are done. I make this cake every time and it always works. It's great because you can put lemon juice, grated orange peel, chocolate chips and pretty much anything in it. NOTE: Zucchini and banana keep the cake moist, and give it a longer life in the fridge before it goes dry and unpleasant. You honestly cannot taste zucchini. If you still do not like it, grate some white chocolate. ;)— — — — — —why toss eyeshadow if you've had it for longer than two years?Bacteria can form in the powder, because you touch the powder, then your eye, then the powder again, and so on. Oil from your skin gets in the powder, and bacteria can form. These bacteria can cause damage to your eyes. Also, realistically, after two to three years, styles change. Frost or metallic eyeshadow comes and goes, color combos change, etc. Changing eyeshadows at least this often has the added benefit of ensuring that the look you are using is not dated.— — — — — —What do you think of Trump's first two years in office?My answer would be just about the same as Todd Smiths answer which I think he did a good job of writing.

I do not care if he is impeached, if they invoke the 25th amendment, if he resigns or if he chokes on one of his Big Macs to the point of incapacitation or death, just so we get rid of the SOB.— — — — — —If an engine has been sitting two years, how to prep it for startup?I have found that a mild 2-stroke mix of oil and gas is really beneficial to an engine that has overhead valves. If this mixture can be delivered to the valve stem shafts and the piston walls,at the very start, of an initial start,of an engine that has sat a while; the additional oil(in the gas)- is very beneficial to stopping any additional wear from happening beyond the few turns of a dry started engine. Every 4-stroke engine will run o.k. with this mixture. The spark-plugs can take this initial 'mixture' very well. The Engine will not reject this fuel mixture in any way. If the engine is carburated, fill the empty float bowls with a 32 to 1 , 2stroke mix; prior to the initial start turnover of the engine. This light oil/gas mix is also good at lubricating the accellerator pump piston,in carbs that have that. Yes-the engine will smoke a bit,when running the first few minutes.That is a good thing! That means that oil lubrication is hitting all the right spots! You get this?

How Do We Know the Exact Torque Needed of a Servo Motor for a Specific Mass?
how do we know the exact torque needed of a servo motor for a specific mass?there are some information that the producer gives, such as the power of the servo motor if the power is specified you can calculate the needed torque in each rotational speed by this formula: T=H/w in which H is the power in watt and w is the rotational velocity in rad/s you should see that in what rotational velocity your device is going to work— — — — — —What's the difference between similarly rated DC motors with different nominal voltages?Usually the difference is the diameter of the windings and the resistance caused to keep an equivalent amount of tourque to reach those speeds.Specific differences will involve looking at the torque vs speed graph, how they build the motor can change this relation, while 2 motors may have the same stall torque and max speed, they can vary widely in how that relationship changes. Equally there can be perks to using lower voltage motors than your supply voltage with similar specifications, e. g. in servo motors, it means in short bursts you can vastly exceed that rating,— — — — — —how can i begin to learn computer programming for running servo motors and the like?as an entry level i would avoid starting with a c and IDE. the expense and complexity are unnecessary.

First, the USB pins are probably driven from a USB PHY chip and so they will only be able to transmit differential USB data. Unless you can fake a USB host on the other end, it may be impossible to transmit anything over the USB pins. Even if you could, I am not sure if the operating system would allow the necessary control. The Micro SD card pins would be a similar story. They are likely driven by an internal SD card controller module, and you would be limited by the capabilities of the module and the interface provided by the operating system. Without having a card connected, it may be impossible to get anything out of the pins. With a card connected, you could be hard pressed to get the signals you want out of the pins.— — — — — —Are there DC motors that can apply constant torque under extended stalled or reversed conditions?A motor that can provide torque continuously or for an extended period of time while stalled is, by definition, a torque motor. Torque motor designs can be implemented using various types of motors, both AC and DC. The design could result in a motor that is physically larger than a continuously rotating motor with the same torque capability. The design could include a separately powered cooling fan and other cooling enhancements.If the motor needs to prevent the load from possible movement in either direction, speed and direction sensing would be required.A servo motor and control system may be required, depending on the overall requirements. Servo motors can be provide performance similar to torque motors in addition to position control. Various types of AC and DC motors can be designed as servo motors.To determine what is the best option, you need to consider every aspect of the requirement including detailed duty cycle, environment, speed range, accuracy requirements, actual torque and speed requirements, number of units required, available budget, expected useful life of the equipment, reliability requirements and probably other factors.— — — — — —do rc servo motors have receivers inside them or do you need to buy one seperate?no, you will need a receiver, possibly only a 2 channel receiver,— — — — — —How to detect high/low signal from a DC servo motor using arduino?Do you need to check if it is stalled? Or simply running?Either way, you could check the voltage with an analogue input, compare against a threshold (empirically set) & use that. Take the voltage reading from the non-commoned side of the motor, after any driver circuit.If you want stalled, a small resistance would help, if just running then you could get away with a digital input. If the voltages are not matched then a resistance divider chain would be necessary

Sure. You can use cooking oil too, if you want - and unless you plan on using USED oil, itu2019s probably cheaper to buy a gallon of olive oil than motor oil - depending on where you get it from.However, and you knew this was coming, right? Proper quenching oil is u201cformulatedu201d (in other words, have the right additives and such) to work well with quenching, rather than work well inside an engine or in your frying pan when you are cooking (or, that extra virgin olive oil, that is excellent on salads, but doesnu2019t really taste well if you heat it up). One of the aspects here is that some of the additives in motor oil may be either directly harmful, or make harmful components when heated to several hundred degrees - normal operating temperature in an engine is much lower than your steel when quenching. These additives are also likely to make the oil u201csmellu201d more than the oil designed for quenching.If you are only doing this once or twice a year, sure, go for your used engine oil.

All you have to do is pop the cover off of the door (yes, the entire panel on the door) and you will see the wires coming from the window buttons down to the window motor.

HELP!!!?When the Ford Mustang window top edge begins to hit the roof drip trim, this is the beginning of trouble. The back section of the two piece window regulator U-channel, on the bottom of the window, is beginning to eject or separate from the window. This is caused by a would esign defect'. The window, fully raised hits the adjustable mechanical up-stop, however, the are gulator' continues to raise the window against the stop rotating the back end of the rear U-channel downward, which raises the rear of the window slightly higher than level. In it's extreme, the front window sliding finger guide can then pop out of the front vertical U-channel guide, causing a misalignment drag preventing the window from traveling to the up or bottom stops. The window basically "floats", held in place at three points in the door. The front of the window is a teflon guide slipper finger riding in an adjustable vertical U-channel. DO NOT READJUST these factory settings. The back end of the window is a plastic roller inside an adjustable captive vertical guide. The last is at the top of the door, they are adjustable window snubbers and a removable weather strip. These points hold the window tightly and maintain a tight friction fit holding the window in suspension while window is in transit between the up or down stops. The proper fix will be to remove the window from the door, Clean and apply new rubbery clear silicone adhesive to the back U-channel and allow amble time to cure. For those having access to metal working facilities, a solid piece, fashioned and fabricated, either bolted or flush pop riveted connecting the front U-channel and the back U-channel, making the two parts as one solid piece, as it should have been in the first place, will prevent the short back end of the back U-channel from rotating downward when hitting the up-stop, ejecting the window glass, which is the design flaw causing this entire problem. To disassemble the door panels, follow the on-line video "replacing a Ford Mustang door regulator". The video is excellent, very detailed, simple lasting about 10 minutes for those unfamiliar with removing the door panels, switches, tabs, water barrier screws, etc
The Working Principle of the Electric Motor
The Working Principle of the Electric Motor
... To maintain a constant speed when driving downhill, if the SOC is below a threshold value, mode 4 operates and can provide a large torque over a short time with a high accuracy. The system uses proportional-integral-derivative (PID) control to achieve a good performance. The calculation function is ... When driving downhill, downhill safety assistance control can ensure a safe speed. A downhill safety assistance system was developed by our research group to help hybrid electric vehicles to maintain a stable speed when driving downhill. For hybrid electric buses, in addition to the pneumatic braking system, the motor can quickly provide an electrical braking torque, and the engine can be considered a mechanical brake. The downhill safety assistance system for hybrid electric buses maintains the desired downhill speed on different road slopes. However, when and how to activate or deactivate the downhill safety assistance system because of the driver's operation or the road conditions was not discussed in combination with the energy management strategy for the vehicle. Additionally, there is currently no dynamic control strategy for the transition process when the braking modes of the downhill safety assistance system change, which can lead to instability. To address the limitations of previous studies, a dynamic coordinated control strategy of the downhill safety assistance system is proposed considering practical application, which focuses on the above two aspects to keep the entire system stable. To improve the ride comfort and the vehicle safety when the downhill safety assistance system works in conjunction with the energy management strategy for the vehicle, the proposed control strategy is developed to activate or deactivate the downhill safety assistance system based on the driver's driving habits and operation and the road conditions in order to reduce the workload and to improve the driveability of the buses. To maintain the ride comfort during the transient process of shift in the braking mode and to maintain a stable speed over the overall course, the mode-shift coordinated control strategy of the downhill safety assistance system is presented, which combines the braking modes to ensure that the braking torque changes steadily without saltation. The experimental results validate the performance of the entire dynamic coordinated control strategy of the downhill safety assistance system with a high stability, and the statistics demonstrate that the downhill safety assistance system obviously improves the fuel economy and reduces the driver workload.1. i have an electric motor but what size of battery do i need to make it rotate at it s maximum potential?No battery will help you with this AC motor that pulls 300 watts of power at 230 volts AC2. What mechanisms / systems are used in electrically driven exoskeleton / robotic arms which enables them to move in all 3 dimensions via receiving power from the electric motor?An exoskeleton or robotic arm does not need the ability of every joint to have six degrees of freedom, as the human body lacks that ability too. Within the constraints of an exoskeleton, the skeleton would simply be tracking and amplifying your body's natural motions. True, some improvements, like unlimited rotation of the wrist might be interesting, but would you really be able to use that for every vertebrae joint too?Power is most accurately and readily distributed electrically, so an exoskeleton would use a combination of centralized and distributed motors, connected by flexible cabling, slip rings and inductive couplings. Control and feedback could be connected similarly, or by radiated links.Perhaps at some time, control and feedback might be done very locally by some type of coupling of the robot to the human's nervous system; that is, the robot's thumb might be coupled directly to the human's thumb nerves.At some far time in the future, perhaps some power source (micro Mr. Fusion's?) might be made so convenient that each motor might have its own discrete power source, so that power distribution would be eliminated.What mechanisms / systems are used in electrically driven exoskeleton / robotic arms which enables them to move in all 3 dimensions via receiving power from the electric motor?3. An electric motor pumps 10,000 kg of water a vertical height of 8m each hour.?The motor draws 5 amps (answer a) and I suppose we are to assume thus consumes 550 watts. The motor consumes energy. It does not generate energy. In one hour, the motor consumes 550 watt-hours of energy (answer b). The potential energy in one hour's worth of water is 10000 * 8 * g, expressed in Newton-meters. Answer c depends on how many hours the motor runs. 1 watt-hour is 3600 Newton-meters, so the motor draws 550 * 3600 Newton-meters in one hour. For d), we have to compare the energy drawn by the motor in one hour to the energy imparted to one hour's worth of water. The motor draws about 2,000,000 Newton-meters, and the water gets around 800,000 Newton-meters of potential energy. Take the ratio of the two to get the efficiency of the system (around 40%).
