The main function of an electric motor is to convert electrical energy into mechanical energy to drive various mechanical devices, while a generator converts other forms of energy, such as chemical energy, water energy, or wind energy, into mechanical energy first, and then converts mechanical energy into electrical energy.

Electric motors have high reliability, and their core components such as the stator and rotor are well-designed, resulting in a long lifespan and extremely low failure rate. During the operation of the motor, the pressure, vibration, and noise are all very small and almost negligible, ensuring its stable and reliable working performance. Electric motors have no smoke, odor, and low noise during operation, making them an environmentally friendly driving method.
