Air cooling system of motor

Abstract

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.

Description

technical field [0001] The invention relates to an electric motor, in particular to an air cooling system for the electric motor. Background technique [0002] Commonly used motors are provided with a windshield on the rear end cover, and a fan is built inside the windshield, which can dissipate the heat inside the motor. However, the windshield and the brush assembly are usually respectively located on both sides of the motor, and the cooling effect of the fan inside the windshield on the brush assembly is limited. [0003] For motors equipped with brush devices, due to the consideration of heat dissipation, sufficient space should be left between the brushes to prevent the life of the equipment from being reduced due to overheating. One of the problems brought about by this is that the size of the equipment is too large, the weight increases, and the space occupied will be larger. At the same time, the handling of the equipment is not very convenient. [0004] Based on t...

However, the windshield and the brush device are usually located on both sides of the motor, and the cooling effect of the fan inside the windshield on the brush device is limited.

[0003] For motors equipped with brush devices, due to the consideration of heat dissipation, sufficient space should be left between the brushes to prevent the life of the equipment from being reduced due to overheating

One problem brought about by this is that the size of the equipment is too large, the weight increases, and the space occupied will be larger. At the same time, the handling of the equipment is not very convenient.
