Abstract

A motor with a cooling function comprises a casing, a rotating shaft, a stator unit, a rotor unit and an air generator. The casing defines an accommodation space, a liquid channel encircling the accommodation space and a gas channel positioned in the periphery of the accommodation space and separated from the liquid channel. The gas channel is communicated with the opposite end of the accommodation space and forms an enclosed air cooling loop together with the accommodation space. The rotating shaft is pivoted to the casing and arranged in the accommodation space in a penetrated way. The stator unit is fixedly arranged in the accommodation space and makes contact with the casing. The rotor unit is arranged in the accommodation space and sleeves the rotating shaft. The stator unit surroundsthe periphery of the rotor unit. and the air generator is arranged in the casing and used to generate an air flow so that the air flow flows cyclically in the enclosed air cooling loop. Thus, the heat radiation effect of the rotor unit can be improved.

Description

technical field [0001] The invention relates to a motor, in particular to a motor with cooling function. Background technique [0002] The rotor unit of the existing induction motor contains a conductor made of copper block. When the current flows through the conductor, it will cause power loss due to the influence of electrical impedance. This power loss is called copper loss, and the copper loss will be dissipated in the form of heat energy Appear. [0003] Generally, in order to dissipate heat inside the motor, a structure such as cooling fins is usually designed on the rotor unit. However, the aforementioned design method will increase the load of the rotor unit during operation, and the load will increase with the increase of the rotation speed of the rotor unit, resulting in a decrease in the operating efficiency of the motor. Furthermore, the aforementioned heat dissipation fins only have the effect of disturbing the air inside the motor, and have limited improvemen...
