Description
Claims (3)
- 펄스폭변조(PWM) 제어에 의해 비엘디씨 모터로 인가되는 전압 및 전류를 조절하여 모터를 구동시키는 제1단계와, 상기 제1단계에서 모터가 구동되는 전류도통구간중에 코깅토크와 자기토크의 방향을 체크하는 제2단계와, 상기 코깅토크와 자기토크가 작용하는 방향에 따라 펄스폭변조(PWM)펄스의 듀티비를 조절하는 제3단계와, 상기에서 조절된 펄스폭변조(PWM)펄스의 듀티비로 상기 비엘디씨 모터에 인가되는 전압을 조절하여 토크리플을 줄이는 제4단계로 이루어진 것을 특징으로 하는 비엘디씨 모터의 코깅토크 리플 저감방법.
- 제1항에 있어서, 제3단계에서 코깅토크와 자기토크가 같은 방향으로 작용하면 펄스폭변조(PWM) 펄스의 듀티비를 감소시키도록 한 것을 특징으로 하는 비엘디씨 모터의 코깅토크 리플 저감방법.
- 제1항에 있어서, 제3단계에서 코깅토크와 자기토크가 반대 방향으로 작용하면 펄스폭변조(PWM) 펄스의 듀티비를 증가시키도록 한 것을 특징으로 하는 비엘디씨 모터의 코깅토크 리플 저감방법.
