Flange mounted clutches are normally off type and operate on DC voltage. On applying DC voltage to the stator (coil) strong magnetic filed is produced, which pulls the armature towards the friction material of the rotor over the air gap and torque gets transmitted free of back lash.

On switching off power supply, the unique prestressed spring pulls the armature back into the original position and clutch is positively released free from residual torque.


Normally off type clutches operate on D.C. voltage, hence A.C. to D.C. conversion is done by means of a suitable rectifier.

Switching of the clutch can be on either side. However, once application demands, higher switching frequency / faster engagement and disengagement time, switching must be carried out on D.C. side. To restrict the high inductive voltage / back EMF a suitable supressor and capacitor network is provided across the contactor coil.
