Description
Technical Field
The utility model relates to a motor, especially a motor with heat radiation structure.
Background
The common motor structure comprises a rotating shaft, a front bearing, a front end cover, a rotor, a base, a stator with windings, a rear end cover, a rear bearing, a cooling fan, a fan cover and the like. Because of the protection level requirement, the front end cover and the rear end cover of the common motor both adopt a closed structure. The cooling fan of the motor introduces cooling air outside the machine body from the through hole at the rear side of the fan cover, and the cooling air is driven by the blades rotating at high speed to form air pressure, and after being radiated by the inner wall of the fan cover, the air pressure blows forwards to the cooling fins on the machine base to realize the cooling of the stator core. However, when the motor operates, the heat generated by the inner walls of the rotor and the stator is difficult to be led out and dissipated in time, so that the working efficiency of the motor cannot be further improved, and the electric energy is wasted, which is not beneficial to environmental protection; meanwhile, the continuous high temperature in the motor can shorten the service life of the motor, and the use cost is improved.
