Air cooling system of motor

An air cooling system of a motor comprises a motor body and a motor shaft; wherein, the motor body is internally provided with a stator and a rotor which is fixed on the motor shaft; one side of the motor body is provided with a fan housing, and the other side thereof is provided with an end cover; the fan housing is internally provided with a fan, the end cover is also internally provided with a fan, and the two fans are installed on the motor shaft. The air cooling system has the beneficial effects that the air cooling system not only plays the role of good thermolysis for the stator and the rotor, but also has excellent radiating effect for the equipment inside the end cover, so as to lead the structure of the equipment inside the end cover to be more compact, thus reducing the size and the occupied space of the equipment, and saving consumptive material. Furthermore, the weight of the equipment is also reduced, so that the transportation is relatively more convenient.
