Claims

[Scope of utility model registration request]

An annular field core arranged concentrically with respect to the output shaft, an electromagnetic coil built in near one end of this field core, a permanent magnet built in near the other end of the field core, and a an input rotor that can be freely fixed and whose back face faces an end surface on the electromagnetic coil side of the field core;
It has a clutch armature that can be magnetically attracted to the front surface of the input rotor, and a brake armature whose purpose is to magnetically attract the end face of the field core on the permanent magnet side. An electromagnetic clutch/brake in which the attached brake hub is fixed to the output shaft, and the clutch armature is attached to the clutch hub via a leaf spring.
