Embodiment 1

[0027] A motor stator of this embodiment, such as Figure 1-5 As shown, it includes a stator core 1 and a winding coil 2 embedded in the stator core 1, the end of the winding coil 2 is located outside the stator core 1, and the end of the winding coil 2 is provided with The cooling conductor 3 is provided with a heat conduction component 4 on the outer peripheral surface of the cooling conductor 3 , and the heat conduction component 4 extends from the inside to the outside of the end of the winding coil 2 to the outside of the end. By arranging the cooling conductor 3 in the end of the winding coil 2, the heat generated by the winding coil 2 is absorbed by the cooling conductor 3, and at the same time, the heat conducting member 4 is arranged on the outer peripheral surface of the cooling conductor 3, and the heat conducting member 4 is extended outward To the outside of the winding coil 2, the heat absorbed by the cooling conductor 3 is used to transfer the heat absorbed by t...

Embodiment 2

[0038] The present embodiment provides a kind of motor, and this motor uses the motor stator described in embodiment 1, because cooling conductor 3 is arranged in the end portion of winding coil 2, utilizes cooling conductor 3 to absorb the heat that winding coil 2 produces, simultaneously A heat conduction member 4 is arranged on the outer peripheral surface of the cooling conductor 3, and the heat conduction member 4 is extended outward to the outside of the winding coil 2, and the heat absorbed by the cooling conductor 3 is transferred out of the winding coil 2 by the heat conduction member 4 to dissipate heat from the winding coil 2 , solve the problem that the performance of the motor decreases due to the poor heat dissipation effect of the end winding coil 2 of the motor stator during the operation of the motor, and serious heat generation, and increase the reliability of the motor.

Abstract

A motor stator and motor, relating to the technical field of motors, the motor stator includes a stator core and a winding coil embedded in the stator core, the end of the winding coil is located outside the stator core, the winding A cooling conductor is arranged inside the end of the coil, and a heat-conducting component is arranged on the outer peripheral surface of the cooling conductor, and the heat-conducting component extends from the inside of the end of the winding coil to the outside of the end. In the present invention, a cooling conductor is provided in the end of the winding coil, and the heat generated by the winding coil is absorbed by the cooling conductor. At the same time, a heat-conducting member is arranged on the outer peripheral surface of the cooling conductor, and the heat-conducting member is extended outward to the outside of the winding coil. The heat absorbed by the cooling conductor is used to transfer the heat absorbed by the cooling conductor out of the winding coil to dissipate heat from the winding coil, which solves the problem of motor performance degradation caused by the poor heat dissipation effect of the end winding coil of the motor stator and serious heat generation during the operation of the motor. The reliability of the motor is increased.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor stator and a motor. Background technique [0002] During the operation of the motor, the heat generated by the winding heating will cause the temperature rise of the motor to be too high, which will affect the performance of the motor. Therefore, a good heat dissipation structure is an important factor to ensure the long-term stable operation of the motor. [0003] In the prior art, the effect of air cooling is poor, and the main method of water cooling and oil cooling is to arrange a cooling shell on the outer periphery of the stator. The cooling shell is provided with cooling channels, and the heat is transferred through the flow of heat dissipation medium (water or oil). The heat generated by the motor, thereby reducing the temperature rise of the motor. However, the heat source of the stator is mainly the end winding coil, and the heat generated by the end winding coi...
