Abstract

A motor cooling mechanism comprises a motor end cover, a shell, a reduction gearbox end cover and an electric controller, the motor end cover is arranged at the first end of the shell, the reduction gearbox end cover is arranged at the second end of the shell, the electric controller is arranged on the shell, and the electric controller is arranged on the shell. A liquid path pipeline is formed among the motor end cover, the shell and the reduction gearbox end cover, the electric controller is arranged on the outer surface of the shell, and cooling liquid moves in the liquid path pipeline according to a preset direction. According to the motor cooling mechanism provided by the invention, the reduction gearbox, the driving motor and the electric controller can be cooled at the same time, and the cooling effect is good; the axial turn-back type channel in the shell ensures that the axial temperature of the cooling liquid is uniform, the motor end cover, the shell and the reduction gearbox are sealed through the sealing rings, the structure is simple, and sealing is reliable.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a motor cooling mechanism. Background technique [0002] Motors are widely used in industry, transportation, equipment and other fields. With the improvement of energy saving requirements, motors are developing in the direction of light weight and high efficiency. The design of the motor generally integrates the drive motor, gearbox, and electric controller. However, during the operation of the motor, the winding current of the drive motor, the friction of the gear train of the gearbox, and the power devices of the electric controller will all generate heat, and the heat accumulation will cause the temperature to rise. , so that the winding resistance increases, the insulation and lubrication properties deteriorate, and the temperature of the power device increases, resulting in a decrease in motor efficiency and even device damage. [0003] At present, motor cooling ...
