Abstract
An electromagnetic clutch assembly for selectively connecting a source of rotative power with a driven component having an input shaft rotatable about a shaft axis features a driven member mounted for rotational movement about the shaft axis. The electromagnetic clutch assembly includes an armature disk constructed and arranged to be drivingly connected with the driven component. The armature disk is stamped within an annular portion thereof to provide oppositely facing convex and concave surfaces, and a frictional material is fixedly disposed within the concave configuration of the convex and concave surfaces. The friction material and the driven member have gripping surfaces, which interengage when a magnetic coil assembly is energized. The electromagnetic clutch assembly may be provided by a method including fixedly disposing friction material within a concave configuration of a disk of magnetic flux transmitting material within an exposed configuration suitable to interengage with a cooperating clutch member.
