Abstract
A friction clutch having first and second clutch members, a plurality of first clutch plates, a plurality of second clutch plates and a first electromagnet. The first clutch member is formed of a first magnetically susceptible material. The first clutch plates are axially slidably and non-rotatably coupled to the first clutch member and are formed of a second magnetically susceptible material. The second clutch plates are axially slidably and non-rotatably coupled to the second clutch member. The second clutch plates are interleaved with the first clutch plates. The first electromagnet has a first pole that is magnetically coupled to the first clutch member. The first clutch plates are driven apart from one another when the first electromagnet is operated to generate a magnetic field.
