Abstract: An electric motor includes an angle sensor, and the angle sensor includes a main body, a hood part, a holding part, a first circuit board, an intermediate flange, a second circuit board, a disk part, e.g., with a dimensional scale, and a hollow shaft. The rotor shaft of the angle sensor is connected to a rotor of the electric motor for conjoint rotation, and the disk part is slid onto the hollow shaft and bears against a shaft step and/or a flat surface region of the hollow shaft. The second circuit board has conducting tracks acting and/or formed as coil winding and is held clamped between the main body and the intermediate flange, and the intermediate flange is pressed towards the main body by the screw head of another screw screwed into a threaded bore of the main body. The first circuit board is held clamped between the intermediate flange and the holding part, and the screw head of a screw screwed into a threaded bore of the intermediate flange presses the holding part towards the intermediate flange.

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.

Abstract: In a method for providing a voltage for a load, e.g., for an inductor and/or coil of an electromagnetically actuable brake, e.g., of an electric motor, and device for carrying out the method, e.g., in a manner repeated over time, the positive half-wave of an, e.g., single-phase AC voltage is provided to the load in a pulse—with modulated manner starting from a first phase angle of the AC voltage, and in an unmodulated manner, e.g., and/or uncontrolled manner and/or directly, starting from a second phase angle.
