Abstract
Description
Claims (3)
- 별도의 압력센서, 압력스위치나 온도센서를 구비하지 않고 흡입구의 막힘 여부를 판별하여 SRM 구동용 인버터를 보호하는 방법에 있어서,(a) 회전자 검지부에서 구동중인 SRM의 회전자의 회전수를 검출하는 단계;(b) 상기 검출된 회전수가 미리 설정된 청소기 흡입구 막힘시의 회전수 이상인지를 판별하는 단계;(c) 상기 검출된 회전수가 설정된 회전수 이상이면, 그 시점부터 카운팅을 시작해서 카운팅 시간이 미리 설정된 경과시간을 넘어서는지를 판별하는 단계; 및(d) 상기 카운팅 시간이 설정된 경과시간을 넘어서면 인버터를 스위칭 오프시키는 단계를 포함하는 것을 특징으로 하는 SRM 구동용 인버터의 보호방법.
- 제 1항에 있어서,상기 단계 (b)의 판별에서 검출된 회전수가 설정된 회전수 미만이면, 프로그램 진행을 상기 단계 (a)로 귀환시키는 단계를 더 포함하는 것을 특징으로 하는 SRM 구동용 인버터의 보호방법.
- 제 1항에 있어서,상기 단계 (c)의 판별에서 카운팅 시간이 미리 설정된 경과시간 미만이면, 프로그램 진행을 상기 단계 (a)로 귀환시키는 단계를 더 포함하는 것을 특징으로 하는 SRM 구동용 인버터의 보호방법.
