They are light in weight, compact and have high torque at low wattage; there are three parts to a clutch: stator (clutch body) which is fitted on the driving side, rotor which fits over the stator and armature plate which is fitted on the driven side
The transmitting torque is generated on supply of DC voltage to the stator; the rotor gets magnetised which in turn attracts the Armature plate and the motion is transferred
The clutch is released by a pre-stressed sinusoidal wave spring when the supply voltage is discontinued; the clutch body is pre aligned to facilitate simple assembly
Clutch diameter – 63mm to 250mm; torque capacity – 7 Nm to 440 Nm; popularly know as P-series bearing mounted clutch; this is a stationary coil clutch; thus carbon brushes are not required; consists of clutch body, rotor, armature plate
Asbestos free liner is used; armature plate is of 2 types: only spring steel armature plate suitable to mount gear sprocket, pulley and spring steel armature plate with back plate; works on 12/ 24 / 42 / 90 V DC, 2 phase supply
Function is to transmit torque from driving to driven; motor can be kept on continuously; clutch is engaged only when torque is to be transmitted
Thus life of motor is increased; these clutches are used in dry applications. Holds/stops the load in desired place; instant stop; highly recommended for inching operations; robust and compact design; maintenance free; easy to install.
