Electromagnetic clutches provide fast and smooth operation of mechanical devices. They operate electrically, and transmit torque mechanically. This type of clutch is used in some vehicles, lawnmowers, copy machines, and conveyor drives
Electromagnetic clutches use a single plate friction surface to engage the input and output of a clutch. They are the most common type of electromechanical clutches.
A clutch has a coil in a shell, typically made of steel and copper wire, and a rotor, which connects to the moving part of the machine. To energise the coil, the unit's electric circuit should be activated, which will cause the current to run through the coil and generate a magnetic field.
There are many types of electromagnetic clutches, such as hysteresis, tooth, multiple disc and magnetic particle. The most widely used type is the single face design, which is typically used in secondary drives, and in textile machines and packing.
