Abstract
Drive devices for coupling a drive mechanism to an input shaft and methods of providing coupling control through an electromagnet are described herein. The drive devices include a driven member operatively coupled to a clutch assembly engageable with an input shaft. The clutch assembly includes an electromagnet, an actuator activated by the electromagnet, and a clutch pack that is biased into increased frictional engagement by the actuator to transfer the torque from the driven member to the input shaft. The methods include providing such a drive device and activating the electromagnet.
