Problems solved by technology

When the motor is working, it may receive various shocks and disturbances. If the O-ring seal is broken or the sealant fails to separate, the sealing of the stator will be directly damaged, and the motor will cause oil leakage accidents, which will affect the reliability and safety of the motor operation. sex

Abstract

The invention relates to a stator sealing structure and a motor with the same. The stator sealing structure disclosed by the invention is used for achieving complete sealing of a motor stator and comprises a first end sealing plate (4) and a second end sealing plate (3), wherein the first end sealing plate (4) and the second end sealing plate (3) are symmetrically arranged at two end parts of thestator (2), a first end sealing plate press ring (6) is correspondingly arranged at an outer side of the first end sealing plate (4), a second end sealing plate press ring (5) is arranged at an outerside of the second end sealing plate (3), a groove cooling pipeline (13) is arranged in a stator groove (204) of the stator (2), and a groove wedge (12) is arranged at the bottom of the groove coolingpipeline (13). In the sealing structure, complete sealing of the motor stator is achieved by arranging the end sealing plates and the end sealing plate press plate at end surfaces of the motor and bypouring the cavity in the motor stator groove opening, and the motor stator and a rotor are effectively isolated; and moreover, a motor air gap space is not occupied by the sealing assembly, the sizeof a motor air gap is relatively small, and the torque density and the power density of the motor are further improved.

Description

technical field [0001] The invention belongs to the technical field of motor cooling, and more specifically relates to a stator sealing structure and a motor with the sealing structure. Background technique [0002] The temperature rise of the motor is directly related to the performance and life of the motor, so the temperature rise of the motor is often suppressed by liquid cooling. At present, oil cooling is a commonly used motor liquid cooling method. Oil-cooled motors can be divided into direct oil-cooled motors and indirect oil-cooled motors according to the cooling method. The indirect oil-cooled motor achieves indirect oil cooling of the motor by opening cooling channels on the motor casing or end cover. The cooling oil cannot directly contact the heat source, that is, the winding and the motor stator, resulting in low cooling efficiency for this solution. The direct oil-cooled motor can obtain better cooling effect by immersing the motor stator or the whole motor ...
