Abstract

The invention provides an inner stator motor cooling device, a motor and an inner stator motor cooling method, which belong to the technical field of motor heat dissipation. The inner stator motor cooling device comprises a mounting seat, a connecting shaft and a liquid inlet pipe. The motor uses the inner stator motor cooling device. The inner stator motor cooling method employs the inner statormotor cooling device. According to the inner stator motor cooling device provided by the invention, a coolant enters from the liquid inlet pipe and flows into a sealing cavity on the mounting seat through a liquid inlet hole, and the heat generated by the stator exchanges heat with the coolant in the sealing cavity to reach the purpose of cooling the stator; after the coolant reaches a certain amount in the sealing cavity, the coolant enters a liquid outlet hole and flows out through the gap between a first blind hole and the liquid inlet pipe to form a stable coolant circulation system. The cooling method is low in punching difficulty and is easy to process. At the same time, the danger that cooling water is likely to enter the motor to burn down the coil when two eccentric holes are opened can also be avoided.

Description

technical field [0001] The invention belongs to the technical field of motor heat dissipation, and more specifically relates to an inner stator motor cooling device, a motor using the inner stator motor cooling device, and an inner stator motor cooling method using the inner stator motor cooling device. Background technique [0002] The motor loss includes copper loss, iron loss, stray loss, etc. Among them, the copper loss and most of the iron loss are located on the stator side. For a motor with an inner stator structure, the heat dissipation area of ​​the inner stator is smaller than that of the outer stator structure. The heat is not easy to dissipate, so that the heat in the motor accumulates, causing the temperature of the motor to rise too high, or even burn out. [0003] The motor with inner stator structure can be air-cooled or water-cooled. The water-cooled structure generally adopts a hole in the middle of the shaft, and water enters and exits at one end or both e...
