Abstract
The disclosure relates to an electromagnetic brake mounted to and used with electric motors. Such brakes have an 'E' shaped electromagnet mounted on a magnet support. An armature block is mounted on a plate and both the block and the plate move when the electromagnet is energized or de-energized. The improvement involves a magnet support of the cantilever type. Such support bends slightly when the electromagnet is energized so that the faces of the 'E' magnet legs can self-align and be maintained substantially parallel with the armature block. The preferred structure also includes a resilient pad interposed between the block and the plate and at least one stop limiting compression of the pad. A special bolt securing plate hold the armature block bolts in place.
