Abstract

The invention discloses a motor with a cooling structure, which comprises a rotor, a stator, a casing and two end covers respectively arranged at two ends of the casing. The structure further comprises a cooling channel arranged in the side wall of the casing, and the casing is provided with a medium inlet and a medium outlet which are respectively communicated with the cooling channel; an axial fan is fixedly connected with the rotor, wherein the rotor is provided with an axial air duct, and the two end covers are respectively provided with a ventilation opening. According to the motor, a stator cooling structure is formed through the cooling channel to realize stator cooling; a rotor cooling structure is formed through the cooperation of the axial flow fan, the axial channel and the ventilation opening, and therfore the cooling of the rotor is realized; in other words, the overall cooling of the motor is realized through the combination of the stator cooling structure and the rotor cooling structure. Compared with the prior art, the motor disclosed in the invention is advantageous in that the stator cooling structure is added, and the rotor cooling structure is improved, so thatthe overall cooling effect of the motor is good, and the cooling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of motors, and more specifically, to a motor with a cooling structure. Background technique [0002] With the development of motors in the direction of permanent magnetization, high power density and high speed, the problem of temperature rise of motors is becoming more and more prominent. [0003] In the prior art, air cooling is usually used to cool down the motor. For example, a fan is added to the rotor, and the rotation of the rotor drives the fan to rotate, so that the air inside the motor can be circulated by the fan during the operation of the motor, so that the rotor The heat of the motor is taken away by the air inside the motor, and then, through the heat exchange between the air and the casing, end cover, etc., the heat is transferred to the outside to realize the cooling of the motor rotor. [0004] It can be seen that this heat dissipation method has a large thermal resistance, and the air cir...
