AI Technical Summary

Technical Problem

Existing methods for cooling switched reluctance motors usually improve heat dissipation by modifying the motor casing, which makes it difficult to achieve active cooling.

Method used

A structure including an active ventilation cooling device, a sealing device, an auxiliary cleaning mechanism and an annular ventilation plate is designed. A high-pressure air pump is used to guide the gas to circulate inside the motor. The built-in partition plate and arc baffle of the annular ventilation plate are used to evenly distribute the gas and prevent backflow. A dust filter plate and a scraper cleaning mechanism are set to prevent dust accumulation, and a sealing device is used to seal the gas.

Benefits of technology

Active ventilation cooling of the motor is achieved, gas backflow and dust accumulation are prevented, heat dissipation efficiency and equipment stability are improved, and instability caused by casing modification is avoided.

Abstract

The application relates to the technical field of switched reluctance motors, and particularly discloses a switched reluctance motor capable of active ventilation cooling. The switched reluctance motor comprises a ventilation pipe, one end of the ventilation pipe is provided with a high-pressure air pump, an annular ventilation plate is arranged as an annular shell with an annular cavity, the inner side of the annular ventilation plate is provided with small ventilation holes I, the outer side of the high-pressure air pump is sleeved with and fixedly connected with an auxiliary cleaning mechanism. The switched reluctance motor capable of active ventilation cooling carries out air exchange type heat dissipation by filling gas into the inner side of the annular ventilation plate and then discharging the gas from the plugging device through the exhaust round hole, the existing cooling means is usually improved by modifying the motor shell to improve the heat dissipation of the motor, and the active cooling and temperature reduction of the motor are difficult to realize, the gas sprayed by the high-pressure air pump is resisted by arranging the arc-shaped baffle on the inner wall of the annular ventilation plate, and the directly sprayed gas from the small ventilation holes I on the opposite side of the ventilation pipe is prevented from being directly sprayed out, so that the gas is evenly sprayed.
