Abstract:
1. An electromagnetically releasing spring-pressure brake for mounting on a machine wall, said brake comprising a rectangularly or squarely configured coil support housing containing a pair of generally elliptical coils, each said coils having associated therewith one of a pair of elongated parallel armatures of rectangular configuration for exerting pressure onto a single side of a common central rotor to urge said rotor against the machine wall, said coils and said armatures positioned on opposite sides of an axis of rotation of said rotor, said rotor being axially movable on an axially splined hub, and two fasteners aligned on a central longitudinal axis of each armature for guiding movement of the associated armature, said fasteners being threaded for attaching the coil support housing to a machine wall and said fasteners positioned in said armatures at the largest possible distance from the axis of rotation of said rotor with each armature being mounted for axial movement on said fasteners to engage the brake rotor for decelerating said rotor or to engage the coil support housing for releasing the brake rotor.
