motor

Abstract

A motor is provided. The motor comprises a housing, a stator and a rotor. The stator further has a plurality of heat dissipation hole groups, each heat dissipation hole group having two first strip-shaped holes arranged on both sides of a corresponding stator slot, each first strip-shaped hole extending in an axial direction of the stator and opening toward a radially outer side of the stator; thehousing is provided with a plurality of second strip holes, and each second strip hole corresponding to a first strip hole. The motor further includes a plurality of first semiconductor cooling sheets, each semiconductor cooling sheet being inserted into a first strip-shaped hole, and a cold end face of each semiconductor cooling sheet facing a stator slot adjacent thereto; an outer heat dissipation device is arranged on the outer surface of the housing; a plurality of first heat conduction fins are included, each of which is connected with an external heat dissipation device, and each of thefirst heat conduction fins is inserted into a second strip hole and a corresponding first strip hole, and contacts with a hot end surface of a semiconductor cooling sheets in the first strip hole. The motor has high heat dissipation efficiency and excellent motor performance.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor with excellent heat dissipation. Background technique [0002] At present, in recent years, with the continuous development of the motor industry, motor manufacturers continue to pursue small size and high power density. More and more materials with high electromagnetic load and thermal load are used in motor design, and the loss generated during motor operation increases. If the overall temperature rise of the motor is too high or the local temperature rise is too high, it will not only reduce the service life of the motor, affect the efficiency, torque and other economic and technical indicators of the motor, but also cause serious deformation of the structural components of the motor, endangering the safety of the motor. In addition, during the working process of the existing motor, the rotor rotates too violently, which will generate strong vibration. The violent vibration will ...

[0002] At present, in recent years, with the continuous development of the motor industry, motor manufacturers continue to pursue small size and high power density. More and more materials with high electromagnetic load and thermal load are used in motor design, and the loss generated during motor operation increases. The overall temperature rise of the motor is too high or the local temperature rise is too high, which will not only reduce the service life of the motor, affect the efficiency, torque and other economic and technical indicators of the motor, but also cause serious deformation of the structural parts of the motor, endangering the safety of the motor operation

In addition, during the working process of the existing motor, strong vibration will be generated due to the excessive rotation of the rotor, which will lead to unstable operation of the motor and affect the stable operation of the motor
