New electric motor technology

True Electric uses a new type of electric motor called a torque motor, which is indeed characterised by its generation of fantastic torque, i.e. the power that makes the motor rotate. Expressed in Newton metres, the torque can reach a thousand or several thousand Nm, which is three to five times more than that provided by most four-cylinder turbo engines.


The electric engine basically delivers the same amount of torque throughout the whole range of revs, from standing still to top speed. This means that the True Electric car does not need a gearbox. The car just starts up and fires off with an acceleration that beats many comparable petrol-driven vehicles. Furthermore, True Electric also uses a new type of electronic control mechanism which makes it possible to reach high revs with this type of engine.

Internal combustion engines have very low torque at low revs and perform best in what can sometimes be quite a narrow band of revs, which is why petrol and diesel driven vehicles require a gearbox.

Electroengine have even developed their engine so that the differential, which is the mechanical gearing system in all vehicles that allows the drive wheels on each side to rotate at different speeds in corners, can be replaced. Without a differential, cars would normally be dangerous to handle and the tyres on the drive wheels would wear down very quickly. The True Electric system has an electronic differential – the engine control mechanism ‘imitates’ the normal differential and improves its performance considerably.


As it does not have a gearbox or differential, power transfer losses are reduced considerably. This gives a True Electric car a longer range than would otherwise be the case before it needs to be recharged. The gearbox in particular is an expensive component in standard cars, the lack of which means that the True Electric car is cheaper to manufacture.

 


Pure electric propulsion - zero local carbon dioxide emissions

A purely electric driven car doesn’t actually emit any carbon dioxide at all. And if it is charged with Swedish electricity then carbon dioxide emissions are very small, as 97% of Swedish electricity does not produce carbon dioxide emissions. This 97% is produced by hydro-electric power, nuclear power, bioenergy and wind energy (2007 figures).


As the EU’s energy and climate protection measures for 2013-2020 start to be implemented, the amount of carbon neutral electricity produced will increase in all member countries. A similar trend towards carbon neutral electricity production is expected in many other countries as well, not least in the USA.
