IPMSM Vector Control using an I/F Initial Operating Method for Drum Washing Machine

I/F 초기 기동 방법을 적용한 드럼세탁기용 IPMSM의 벡터제어

Because few signals are generated using low resolution position sensor at low speed, rotor position estimation is difficult in drum washing machine application. Besides, inertia of water and drum affect the initial operation load up to two times of rated load. Therefore overcurrent can be occurred at initial operation. In this paper, IPMSM vector control for drum washing machine is proposed by applying I/F initial operating method and sensorless control. And we verify the performance through experiment.
