Abstract

The invention relates to a switched reluctance motor controller which comprises an STC single-chip microcomputer; the STC single-chip microcomputer receives control signals sent by a handle and a button control circuit, position signals sent by a rotor position sensor detection circuit and current signals sent by a current detection circuit; the STC single-chip microcomputer is connected with a power converter through a driving circuit; the output end of the power converter is connected with an SR motor; and a storage battery respectively supplies power to the STC single-chip microcomputer and the power converter. The switched reluctance motor controller has simple circuit structure and few power switch tube devices, reduces the system cost, can prevent the power converter from straight-through faults, has high reliability, small start-up current, large starting torque and good low-speed performance, and does not produce impact current phenomenon that an asynchronous motor is started.

Description

technical field [0001] The invention relates to a switched reluctance motor, in particular to a switch reluctance motor controller. Background technique [0002] The switched reluctance motor control system is a new type of AC control system developed in the 1980s. The switched reluctance motor is integrated with modern power electronics technology and control technology. Advantages, there are formal SRD products abroad, which are used in various fields such as traction transportation, general industry, aviation industry, and household appliances, showing strong market competitiveness. At present, there are several domestic companies engaged in the research of switched reluctance motor control system, but the circuit structure is complex, the cost is high, the realization effect is not ideal, and the noise is large. Contents of the invention [0003] The object of the present invention is to provide a switched reluctance motor controller with simple control circuit, low c...
