ABSTRACT:
The invention is based on a braking device for an electric motor with a stator (14, 16, 18) and a rotor (10), in particular for a direct current series-wound motor, with a braking element (20) that can be moved between an operating position and a braking position depending on a magnetic flux in the stator (14, 16, 18), wherein there is an air gap (32) between the braking element (20) and the stator (14, 16, 18), and with a short-circuit ring (38) for suppressing mechanical vibrations. The invention proposes that the short-circuit ring (38) be inclined in relation to the air gap (32) between the stator (14, 16, 18) and the braking element (20).
