Abstract

The invention provides an inner stator motor cooling device, a motor and an inner stator motor cooling method, belonging to the technical field of motor heat dissipation. The inner stator motor cooling device includes a mounting seat, a connecting shaft and a liquid inlet pipe. The motor adopts the inner stator motor cooling device. The inner stator motor cooling method adopts the inner stator motor cooling device. In the inner stator motor cooling device provided by the present invention, the cooling liquid enters from the liquid inlet pipe, and flows into the sealed cavity on the mounting seat through the liquid inlet hole, and the heat generated by the stator exchanges heat with the cooling liquid in the sealed cavity to achieve For the purpose of cooling the stator, after the cooling liquid reaches a certain amount in the sealed cavity, it enters the liquid outlet hole, and flows out through the gap between the first blind hole and the liquid inlet pipe, forming a stable cooling liquid circulation system. This cooling method is less difficult to drill holes and is easy to process. It also avoids the danger of cooling water entering the motor and burning the coils due to the opening of two eccentric holes.

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...
