Claims

[Scope of utility model registration request]

It has a field core that incorporates a permanent magnet and a depolarizing electromagnetic coil between an inner pole and an outer pole, and an armature that is attached to the side of a rotating member to be braked so as to be able to freely magnetically attract the end face of the field core. In this negative-actuating electromagnetic brake, a predetermined width in the axial direction of the outer pole of the field core is formed as a magnetic insulation layer made of a non-magnetic material. A long ring member made of a magnetic material is attached to the outside of the outer pole so that it can freely slide closely in the axial direction along the outer peripheral surface of the outer pole, and the ring member is provided with a bolt for adjusting the position in the axial direction. Negative action type electromagnetic brake equipped with a bolt for fixing at the node position.
