Abstract

The invention discloses an active heat dissipation device of a switched reluctance motor controller. The device comprises a box body, and a switched reluctance motor is fixedly mounted on one side inthe box body; the front end of a rotating shaft of the switched reluctance motor penetrates through the box body and is rotationally connected with the box body through a sealed bearing; a first bevelgear is fixedly mounted on the periphery of the rotating shaft of the switched reluctance motor, a second bevel gear is meshed and matched with one side of the first bevel gear, the middle of the right side of the second bevel gear is fixedly connected with the left end of a transverse shaft which is rotatably mounted on the box, and a conical friction wheel is mounted at the right end of the transverse shaft through a spring telescopic shaft. The device is simple in structure, ingenuous concept, and the flow direction of heat dissipation air can be adjusted according to the rotating speed change of the reluctance motor, so that heat dissipation is more uniform, reverse air cleaning can be carried out on the filter screen, the reluctance motor is linked with the heat dissipation device, the use of a driving motor is saved, the rotating speed of the heat dissipation device is adjusted according to the rotating speed of the reluctance motor, the market requirement is met, and the air conditioner is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of motor cooling devices, in particular to an active cooling device for a switched reluctance motor controller. Background technique [0002] The loss generated during the operation of the motor increases, resulting in an excessively high overall or local temperature rise of the motor, 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 components of the motor , endangering the safety of the motor, and affecting the normal operation of the controller of the motor.

[0002] The loss generated during the operation of the motor increases, resulting in an excessively high overall or local temperature rise of the motor, 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 components of the motor , which endangers the safety of the motor and affects the normal operation of the controller of the motor

In particular, the switched reluctance motor mainly consists of four parts: a switched reluctance motor, a power converter, a controller and a position detector. The heat generated during the operation is easily absorbed by the controller, which will cause the controller to malfunction and affect the operation of the switched reluctance motor; The volume of dust affects the heat dissipation of the motor, and the cooling air flow direction remains unchanged, resulting in uneven heat dissipation of the motor. The heat dissipation effect of the air inlet is good, and the heat dissipation efficiency of the air outlet is low. The power device of the heat dissipation device needs to be equipped with an independent drive motor to drive the motor to run. The same heat dissipation leads to a decrease in the heat dissipation effect and cannot meet the actual needs, so we invented an active heat dissipation device for the switched reluctance motor controller
