The biggest advantages of electric vehicles are environment friendly and save money. The prospects for development are very promising, electric cars eventually replace gasoline is no longer a dream. Batteries, motors, electric vehicle control system is the three core technology of electric vehicle, BYD Chairman Wang said that it is more simple to make four-wheel drive electric vehicle, the most important thing is to add motor on the line. As the output of battery is DC current, but it will engender the friction when the brush DC motor commutator running, it will limit the speed of electric vehicles. However, permanent magnet brushless motor which made of magnetic materials with high power density and efficiency, and wide speed range, the outstanding advantages is small size, light weight (the ratio of mass is 0.5 -1.0kg/Kw), high efficiency, maintenance-free, wide speed range and using electronic exchange to replace the mechanical commutator, brushless motor has become the mainstream motor variety of electric vehicles.
