Abstract

The invention provides a switched reluctance motor (SRM) and a brake circuit thereof, and belongs to the technical field of motor braking. The brake circuit which includes a first switch module, a second switch module, a time control module, a work voltage generation module and a brake DC generating module is used; when a switch circuit connected with the brake circuit is in a first conduction state, the second switch module in the first conduction state, and the brake circuit enters a driving state; and when the switch circuit in a second conduction state, the first switch module in the first conduction state, the second switch module enters the second conduction state, the brake circuit enters a braking state, and further the switched reluctance motor is braked. The brake circuit can set different braking time according to practical requirements, the safety and reliability are high, and the problem that a present SRM causes that the human body or equipment using the SRM tends to damage due to too long braking time is solved.

Description

technical field [0001] The invention belongs to the technical field of motor braking, in particular to a switched reluctance motor and a braking circuit thereof. Background technique [0002] The rotor of the Switched Reluctance Motor (SRM) is made of laminated ordinary silicon steel sheets, which has the advantages of simple structure, reliability, low cost, and high power factor, and the SRM does not require brush commutation and the rotor does not need to install permanent magnets. , which makes SRM have a good development prospect. [0003] However, in some applications of SRM, if the equipment using SRM needs to brake quickly in case of emergency to prevent damage to the human body or the equipment using SRM, since the SRM rotor has no permanent magnets and no cogging torque, Therefore, if the SRM needs to stop at a high speed, it can only rely on the friction of the rotor shaft for braking. This process takes a long time and can easily cause damage to the human body o...
