Abstract
An electro-magnetic coil assembly mounted to a clutch assembly, the electro-magnetic coil assembly including a coil mounted within an annular coil housing and a flexible armature plate. The coil assembly adapted to generate an electromagnetic field between the coil and the armature plate for attracting the armature plate to the coil assembly. The flexible armature plate includes an annular plate with an outer edge and an inner edge, the outer edge defining an outer periphery, the inner edge defining an inner periphery. Tangs spaced about the inner periphery extending radially inward from the inner edge. Inner notches spaced about the inner periphery of the annular plate and extending radially outward to a point at least halfway in the radial direction between the inner edge and the outer edge. Outer notches spaced about the outer periphery between and extending radially inward to a point at least halfway in the radial direction between the outer edge and the inner edge.
