ELECTROMAGNETIC COUPLING DISC Abstract of the Disclosure The non-working face of a coupling disc (i.e., the armature or rotor) of an electromagnetic coupling such as a clutch or brake is formed with radially spaced rows of angularly spaced grooves separated by radially extending bridges. The grooves terminate short of the working face of the disc and delineate magnetic poles in the disc. In some embodiments, radially spaced rows of grooves also are formed in the working face of the disc. In still other embodiments, excess metal resulting from rolling of the grooves in the non- working face of the disc is used to form integral locating flanges or the like adjacent the disc.
