Abstract

본 발명은 SRM(SRM:Switched Reluctance Mortor)의 회전자 위치를 판별하는 기술에 관한 것으로, 종래의 SRM에 있어서는 회전자의 위치를 검출하기 위하여 모터의 센서를 취부하여야 하므로 모터의 내부 또는 외부에 센서를 취부하기 위한 공간을 필요로 하게 되고, 모터가 고온에서 동작하는 경우, 일반적인 센서는 동작하지않아 특수한 센서를 사용하여 되는 결함이 있었는바, 본 발명은 모터의 회전자 위치를 판별하기 위하여 별도의 센서를 설치하지 않고도 각 상전류 변화를 검출하여 회전자의 위치를 판별할 수 있게 한 것이다.The present invention relates to a technique for determining a rotor position of an SRM (SRM: Switched Reluctance Mortor). In the conventional SRM, the sensor of the motor must be mounted to detect the position of the rotor. When the motor is operated at a high temperature, there is a defect that a general sensor does not operate and a special sensor is used. Therefore, the present invention provides a separate motor to determine the rotor position of the motor. It is possible to determine the position of the rotor by detecting each phase current change without installing a sensor.
