A clutch is used to engage or disengage a motor when there is a need for frequent starts and stops.
Upon activating the clutch, a magnetic field is produced once current flows right through the electromagnet. As a result, the rotor part of the clutch is magnetized, and this creates a magnetic loop attracting the armature. Then, this leads to the pulling of the armature against the rotor, which generates frictional force at contact. Load becomes accelerated, which matches the rotor's speed, and this engages the output hub of a clutch and the armature.
