Abstract

본 발명은 고속회전을 위한 리럭턴스 모터의 스타트 보강회로에 관한 것으로, 종래에는 고속회전으로 인해 토오크가 제로인 구간이 존재하게 되어 로터는 정지상태에서 모든 방향으로 대칭이되어 회전력이 없으므로 초기 스타트를 하지 못하는 문제점이 있었다.The present invention relates to a start reinforcement circuit of a reluctance motor for high speed rotation, and in the related art, there is a section in which torque is zero due to high speed rotation, and thus the rotor is symmetrical in all directions in a stop state, and thus does not have an initial start. There was a problem.

이와 같은 종래의 결합을 감안하여 본 발명은 고속으로 회전하는 리럭턴스 모터에서상 전진(phase advancd)시 발생하는 작은 토오크 영역에서 센서와 관계없는 다른 상(phase)을 여자시켜 일단 가동하게 한 후 로터가 회전되었다는 것을 감지한 후 정상적인 센서의 출력에 맞추어 각 상을 여자시키도록 하여 상 전진의 양에 제한받지 않도록 함과 아울러 고속회전을 원하는 SRM에서 스타트 문제를 해결하도록 한 효과가 있다.In view of such a conventional coupling, the present invention excites the other phases irrelevant to the sensor in the small torque range that occurs during phase advancing in a revolving motor rotating at high speed, and then operates the rotor once. After detecting that the rotation has been rotated, each phase is excited by the output of the normal sensor so that it is not limited by the amount of phase advancement and solves the start problem in the SRM which wants to rotate at high speed.
