Claims

[Claims for Utility Model Registration] 1. A motor having a rotating shaft that protrudes from a motor housing and has a stepped portion formed on a portion of the rotating shaft, and at least a portion of the rotating shaft is engaged with the stepped portion of the rotating shaft. a support body rotatably attached to the rotation shaft integrally with the rotation shaft; an armature supported by the support body so as to be movable in the direction of the rotation axis of the rotation shaft via an elastic member;
It consists of an electromagnetic device for attracting the armature against the elastic force of the elastic member, and a friction member fixed to the motor housing for applying a frictional force to the armature attracted by the electromagnetic device. An electromagnetic device with adjustable gap, characterized in that a plurality of spacers for adjusting the gap between the armature and the friction member are stacked and arranged between the stepped portion of the rotating shaft and the support body. Motor with brake. 2. The gap-adjustable electromagnetic brake motor according to claim 1, wherein the support body has a pulley replaceably attached by a screw.
