PERFECCIONAMIENTOS EN MOTORES ELECTRICOS DE EMBRAGUE Y FRE- NO.

摘要

An electric coupling and brake motor comprises a continuously rotating main or drive shaft of the motor and an output shaft coaxially therewith, on which a cylindrical coupling member is coaxially mounted for rotation therewith and axially immovable with respect thereto. A flywheel is mounted on the drive shaft for rotation therewith and axially movable with respect thereto and facing one of the end faces of the coupling member, and a brake abutment member is mounted in the motor housing movable only in axial direction toward and away from the other end face of the coupling member. The motor includes further electromagnet means for selectively moving the flywheel or the brake abutment member in axial direction into frictional engagement with the respective end face of the coupling member to rotate the output shaft together with the drive shaft or to hold the output shaft stationarily during rotation of the drive shaft.
