Product Profile of Normally Off Clutches
Electromatic Engineers Pvt. Ltd. an ISO:9001:2000 Company, under the brand name Unitorq is the manufacturer of group industrial clutches and brakes. Being a part of that Normally off Clutches are Flange mounted clutches are normally off type and operate on DC voltage. Salient features of Normally off Clutches are as follows:
1. Normally off type clutches operate on D.C. voltage, hence A.C. to D.C. conversion is done by means of a suitable rectifier.
2. Switching of the clutch can be on either side.
3. However, once application demands, higher switching frequency / faster engagement and disengagement time, switching must be carried out on D.C. side.
4. To restrict the high inductive voltage / back EMF a suitable suppressor and capacitor network is provided across the contactor coil.
