Abstract: The invention relates to an electric motor (1) with a rotor (2) and a housing (3) that has at one end a brake-mounting end shield (4) to support a shaft (5) of the rotor (2) that passes through the brake-mounting end shield (4). The electric motor (1) further comprises an electromagnetically actuated brake (10), which comprises a magnet body (17) with a brake coil (11). An armature plate (13), which can be pulled by the magnet body (17) against a braking pressure force exerted by springs (12), is substantially nonrotatably mounted in a guide mechanism (15) but can be axially displaced in the direction of the shaft (5). A brake rotor (20), against which the armature plate (13) is apposed with the braking pressure when no current is flowing through the brake coil (11), is fixed to the shaft (5), preferably by way of a drive element (28).

Abstract: An electromagnetically actuated brake is provided comprising a magnetic body, which can energized electromagnetically to produce a magnetic force, and a brake rotor which is mounted on a shaft, in particular the drive shaft of an electric motor, in a rotationally stable manner, so that the shaft can be braked. A spring-loaded armature plate is mounted on the shaft and is movable axially parallel to the long axis of the shaft by the magnetic force produced in the magnetic body against the force of its spring loading whereby in a braked state the armature plate is apposed to the braking surface of the brake rotor. Disposed between the armature plate and the magnetic body or between the armature plate and the brake rotor are first and second dampers to attenuate oscillations of the brake. The first and second damper are located adjacent one another in the axial direction of the shaft and each comprises a material different from that of the other.
