The electromagnetic clutch works by a magnetic field, which produces the electromagnet, that draws electricity from the car's installation. Break in the electric circuit (disengages or engages the clutch. A solenoid circuit breaker is usually installed on the gearshift lever, that is, movement of the lever interrupts or turns on the flow of electricity to the electromagnet and engages or disengages the clutch.
The advantage of an electromagnetic clutch is its gradual engagement, which allows the car to move smoothly. The disadvantage of this clutch is a rather complicated structure and the dependence of the clutch operation on the car's electrical system, the faults of which are relatively the most common. We divide electromagnetic clutches into two groups. The first group includes clutches with friction plates pressed down by a magnetic field. Clutches belong to the second group, in which the elements are coupled together by a substance that sets in a magnetic field, usually ferritic paste or metal powder.
