ABSTRACT OF THE DISCLOSURE A compact electromagnetic clutch has a toothed armature connected to a driven hub and a toothed driving hub which are moved into engagement with each other upon energization of an electromagnet. A precompressed spring disposed between the bottom of a cylindrical cup attached to the armature and the head of a pin attached to the driven hub biases the arma- ture away from the driving hub. The precompressed spring provides a force strong enough to overcome residual magnetism, The spring is further compressed when the armature moves into engagement with the driving hub upon energization of the electromagnet. After de-energization of the electro- magnet, the precompressed spring biases the armature away from the driving hub disengaging the armature teeth from the teeth of the driving hub. The electromagnet is provided with a shaped coil and a conventional ball bearing rotatably supports the driving hub to form an economical compact clutch.
