Abstract
In an electric motor having electromagnetically actuatable brake, the brake has a coil received in a magnet body. A brake lining carrier is connected, rotation-fast but axially displaceable, to a rotor shaft of the electric motor, and an armature disk is connected, rotation-fast but axially displaceable, to the magnet body. The armature disk is arranged axially between the brake lining carrier and the magnet body. Springs supported on the magnet body press on the armature disk. A second electromagnet is arranged on the magnet body. A lever is pivotably mounted relative to and/or on the magnet body. The lever is connected to the armature disk, such that in a first rotational position of the lever, the armature disk is pressed towards the brake lining carrier, and in a second rotational position of the lever, the armature disk is kept pulled towards the magnet body.
