Role cub motorcycle manufacturer electric car gear drive torque is transmitted to the car's drive shaft of the motor, when the use of electric-wheel drive, the majority gearing member often ignored. Because the motor can start with a load, so without the traditional internal combustion engine vehicle clutch on electric vehicles. Because the drive motor rotation can be achieved by converting circuit control, the electric car without internal combustion engine vehicle transmission in reverse. When using variable speed control motors, electric vehicles can be ignored traditional car transmission. When using electric wheel drive, electric cars may be omitted traditional internal combustion engine vehicle driveline differential.
The drive motor is the role of the power of the electrical energy into mechanical energy, by gear or direct drive wheels and the working device. Vertical motorcycle engine widely used in today's electric cars dc series motor, the motor has a "soft" mechanical properties, very consistent with the driving characteristics of the car. However, due to the presence of DC motor commutation spark, less power, less efficient, maintenance workload, with the development of motor technology and motor control technology, is bound to gradually than brushless DC motor (BCDM), a switched reluctance motor (SRM) and AC induction motor replaced.
