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
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
