Abstract

본 발명은 스위치드 릴럭턴스 모터 구동회로에 관한 것으로, 종래의 스위치드 릴럭턴스 모터는 센서를 모터에 장착해야 하므로 여러가지 기계적 가공을 해야 하며 센서를 설치할 공간을 확보해야 하고, 또한 모터내부가 고온 또는 콤프레서와 같은 냉매 윤활유등을 튀기며 혼잡한 양상을 일으킬때 센서가 오동작하는 문제점이 있었다.The present invention relates to a switched reluctance motor driving circuit, and the conventional switched reluctance motor has to be equipped with a sensor to the motor, so that various mechanical processings must be performed and a space for installing the sensor must be provided. There was a problem that the sensor malfunctions when splashing the same refrigerant lubricating oil and the like causes congestion.

본 발명 회로는 이와같은 종래의 문제점을 감안하여 센서를 사용하지 않고 스위치드 릴럭턴스 모터 권선에 흐르는 전류를 검출하여 스위치드 릴럭턴스 모터 구동신호로 사용하는 스위치드 릴럭턴스 모터 구동회로를 창안한 것이다.In view of such a conventional problem, the present invention devises a switched reluctance motor driving circuit which detects a current flowing through a switched reluctance motor winding and uses it as a switched reluctance motor driving signal without using a sensor.
