The Crowdfunded Flat-pack Car That Will Democratize Motoring

Only one in eight people in the world have access to a motorised vehicle. The OX is looking to change that.Imagine an affordable, flatpack, utility vehicle, purpose-designed for use in all manner of difficult terrain and flexible enough to perform a multitude of humanitarian tasks. Designed by partners The Norman Trust, The Global Vehicle Trust and Gordon Murray Design, the OX is set to change the face of transport in the areas of the world where this is most needed.

"You go out to Africa, the third world and most people don't have mobility, access to transport, it's shocking. The OX is practical but also a great vehicle to drive," says Frank Coppuck, Technical Director at GMDThe vehicle is designed to be as capable and flexible as possible in difficult conditions so features generous approach and departure angles and a high clearance. Each wheel of the two-wheel drive system is independently suspended to allow for the roughest of trails and the OX is also light, with marine grade plywood used wherever possible to ensure minimal fuel consumption.

The prototype OX I saw was fitted with a 2.2Ltr petrol engine but this can be swapped out easily to an engine suited to the available local fuel supply. River crossings or flooded roads are no problem as the air intake is 1m off the ground, but make sure you take your swimming trunks if you go that deep!Across the developing world, and Africa in particular, there is an intense need for improved transport both for everyday living as well as emergencies.

Even though 15% of the world's population lives in Africa, there has never been a vehicle specifically designed and manufactured in volume to meet the rigours of the continent. Food, water, medicine, schools and transport are dependent for their daily needs on unreliable vehicles and uncertain availability. The vehicles that are available are often designed for quite different purposes, are too heavy, too complicated and unsuited to local conditions.

Frank went on to explain that the OX is designed to be as simple as possible to fix as facilities to repair and modify vehicles are basic or non-existent in Africa. No on-board computers here and the literal nuts and bolts are all standard, universal sizes that basic tool kits can deal with. It is designed for an everyday person to be able to fix and repair and features some cunning bits of design to allow for dealing with common problems.

The air intake filter is simply a chunk of plastic foam that can easily be removed, the dust banged out and replaced in seconds while the windscreen is made of three identical plastic panels that can be swapped around if one is broken or cracked by flying stones. Simplicity is the name of the game here, and the entire top half of the vehicle is modular, to enable conversion to whatever purpose the user needs, be it a portable school, a water transport or an ambulance.The OX is a highly unconventional 'flat-pack' all-terrain light truck, which will benefit people living in remote villages and townships across Africa and other parts of the developing world.

A vehicle that will provide mobility for rural areas in developing countries with poor infrastructureLightweight, rugged and durable to maximise payload for goods and peopleCapable of operating in adverse terrain and hostile conditionsLow cost, designed for simple maintenance with fewer partsDesigned for self-assembly using simple procedures and instructionsSupplied fully assembled or flat-packed for easy shipping and local assemblyThe Ox was conceived by one of the UK's leading philanthropists, Sir Torquil Norman, who is recognised for his charitable work with disadvantaged young people through his charity The Norman Trust. To take the idea off the drawing board Professor Gordon Murray, designer of the McLaren F1 supercar, jumped on-board and threw some of the design team from his automotive technology company GMD behind the project on a not-for-profit basis."Sir Torquil came with the concept and said this is what I'd like to achieve, Gordon loved it and this is the result!" enthused CoppuckThe Trust and GMD have spent approximately £3 million bringing the OX to the working prototype stage.

Preliminary engineering design, extensive component selection, benchmarking and testing was undertaken by GMD to increase confidence that the OX will cope with all of the environments that it is likely to be put to work in. The prototyping stage of the OX development has seen three versions built: XP1, XP2 and XP3."This is proof of concept. Now we need to get it into production, to get it from 95% bulletproof to the 100% stage.

We want them to be so robust, so durable, we want them to last forever." Coppuck explainedThe next stage is further engineering improvements and updates followed by testing on the ground in Africa. To fund this The Norman Trust and The Global Vehicle Trust are seeking £450,000 via a Crowdfunder.

There's nothing else like it on the planet.

What is the working principle of an electric motor ?

An electric motor uses the attraction and repulsion of magnetic fields to produce motion. The simplest is the permanent magnet motor. A simplified version is shown below.Placing a coil of wire inside a permanent magnetic field and fixed so it can freely rotate.

Pass a current through the coil of wire and it will rotate to the perpendicular position. Now reverse the current flow and the coil will spin 180 degrees. The brushes and the commutator does the switching directions of the current through the coil at the appropriate moment to keep the coil rotating in one direction.

This is the basics of all electric motors.Fleming's left hand rule above describes the relationship between the main magnetic field. The current flowing in the coil and the direction of the movement or forceNow we can use electronics to do the switching instead of the commutator and brushes.

These motors are called Brushless DC motors.Larger motors require a stronger magnetic field and more electrical ,power to drive it faster and with more torque. Stronger magnetic fields are created by electromagnets.

AC motors use induction from the stationary windings to create the second magnetic field in the rotor. That induces currents in the rotor and these currents have their own magnetic field which interact ( repel and attract) with the main magnetic field to make the rotor rotate
