ABSTRACT:
An over-running clutch is provided having an outer race and an inner race defining a varying gap therebetween. A plurality of rolling elements are positioned between the inner and outer races and are interconnected by a retainer. A rotor is secured to the outer race by a non-magnetic sleeve. An armature is rotationally locked to the retainer. Mounted onto the rotor and adapted to produce an electromagnetic flux to attract the armature into contact with the rotor is an electromagnetic coil; wherein rotation of the outer race is frictionally transferred to the armature and the retainer, thereby moving the rollers such that the rollers engage and wedge between the inner and outer races to lock the clutch.
