Problems solved by technology

However, in the prior art, a fan is usually installed at one end or outside of the motor, and the rotation of the fan is used to drive the airflow into the motor to realize cooling and cooling of the windings of the motor. However, the end of the stator winding cannot be cooled sufficiently, resulting in The overall cooling effect is poor, which affects the normal operation and service life of the stator winding and the motor

Abstract

The invention relates to the technical field of motor cooling, and provides a motor stator cooling system and a motor, the motor stator cooling system comprises a stator sleeve, a stator core and a stator winding, the stator sleeve comprises a first sealing cavity, the first sealing cavity is connected with the stator core and wraps the stator winding, the interior of the first sealing cavity is suitable for being provided with a cooling medium, and the first sealing cavity is provided with a liquid inlet structure, a first cooling channel and a liquid outlet structure which are used for flowing of the cooling medium and are sequentially communicated; and according to the invention, the cooling medium in the first sealing cavity is used for cooling the stator winding, and compared with a heat dissipation and cooling mode that an external fan is used for blowing air for the existing stator winding, the stator winding is wholly immersed in the cooling medium, so that the stator winding can be fully cooled, the cooling effect on the stator winding is improved, and the normal operation and service life of the stator winding and the motor are ensured.

Description

technical field [0001] The invention relates to the technical field of motor cooling, in particular to a motor stator cooling system and a motor. Background technique [0002] The motor will heat up after running for a period of time, which may cause damage to the insulation of the windings. It is necessary to cool the motor to make it work within a safe temperature range. However, in the prior art, a fan is usually installed at one end or outside of the motor, and the rotation of the fan is used to drive the airflow into the motor to realize heat dissipation and cooling of the windings of the motor, but the end of the stator windings cannot be sufficiently cooled, resulting in The overall cooling effect of the motor is poor, which affects the normal operation and service life of the stator winding and the motor. Contents of the invention [0003] The problem solved by the invention is how to effectively reduce the working temperature of the stator winding of the motor. ...
