ABSTRACT:
In an electric motor regulating and control drive, especially for industrial sewing machines, a clutch-brake disk is mounted for co-rotation on an output shaft and has a clutch facing which can be brought into engagement with a clutch surface of a flywheel of the corresponding motor, and has a brake facing which can be brought into engagement with a brake surface of a brake-bearing plate. In order to achieve by simple means an effective suppression of impact noises when a braking action is initiated, at least the brake facing is mounted with damping with respect to the armature ring of the clutch-brake disk. It is preferably thrust against the armature ring by means of at least one annular spring.
