    Abstract: A motor vehicle clutch includes an axis of rotation, a pressure plate, a cover, an apply spring, a release bearing, a stator housing, a stator, a rotor, a rotor housing and a plurality of cam followers. The pressure plate is concentric with the axis of rotation. The cover extends radially over the pressure plate. The apply spring is disposed between the cover and the pressure plate and biases the pressure plate away from the cover. The release bearing is concentric with and axially displaceable along the axis of rotation and is connected to the apply spring for selectively deflecting the spring with axial movement. The stator housing is stationary and is concentric with the axis of rotation. The stator is fixed within the stator housing and has a plurality of poles with windings there about. The rotor is also concentric to the axis of rotation and is operably excited by the stator. The rotor housing is fixed to the rotor. The rotor housing has a plurality of cam ramps arcuately disposed about the axis.
