Embodiment

[0018] Embodiment: a motor liquid cooling structure, the outer side of the stator core 1 of the motor is wound with a winding 2, the stator core 1 wound with the winding 2 is fixed on the motor shaft 3 through a bracket 8, and the motor casing 4 is axially two The end seal is fixed with an end cover 5, and the integral dynamic seal formed by the end cover 5 and the casing 4 is sleeved on the outside of the stator core 1 wrapped with the winding 2. The casing 4, the end cover 5, the motor shaft 3 and the A sealed annular space 6 is formed between the stator cores 1 wrapped with windings 2, and a cooling liquid 7 is provided. The cooling liquid 7 is contained in the annular space 6. Under the combined action of the rotation of the cover 5, the agitation of the ribs 51 inside the end cover and the centrifugal force, the cooling liquid 7 moves in the sealed annular space. When the cooling liquid 7 flows through the winding 2 and the surface of the stator core 1, the winding 2 and ...

Abstract

The invention discloses a motor liquid cooling structure. Windings are wound on the outer side of the stator iron core of the motor, and the stator iron core wound with the windings is fixed on the motor shaft through a bracket. The integral dynamic seal formed by the cover, the end cover and the casing is sleeved on the outside of the stator core wound with windings, and a sealed ring is formed between the casing, the end cover, the motor shaft and the stator core wound with windings There is a cooling liquid in the ring-shaped space, and the cooling liquid is accommodated in the annular space. When the motor is working, due to the rotation of the shell and the end cover, the agitation of the ribs inside the end cover and the centrifugal force, the cooling liquid is in the sealed The annular space of the motor generates movement. When the coolant flows through the surface of the winding and the stator core, the heat on the winding and the stator core is taken away, so that the heat is quickly transferred to the shell and end cover of the motor to achieve rapid cooling. The motor will not be burned due to high temperature even under the condition of high-speed rotation or high-power operation, which effectively prolongs the service life of the motor.

Description

technical field [0001] The invention relates to a motor cooling structure, in particular to a motor liquid cooling structure. Background technique [0002] At present, the heat generated by the motor winding is transmitted to the motor shell and end cover through radiation, and is absorbed by the shell and end cover, and then dissipated to the outside of the motor, and is dissipated by air cooling. The heat is difficult to dissipate quickly, which will easily lead to the aging of the motor and affect the service life of the motor. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a motor liquid cooling structure, the motor liquid cooling structure is simple, the heat transfer is fast, and the cooling is sufficient. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a motor liquid-cooled structure, the stator core of the motor is wound with windings, th...
