Publication number: 20230344305Abstract: 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.Type: ApplicationFiled: September 2, 2021Publication date: October 26, 2023Applicant: SEW-EURODRIVE GMBH & CO.

Patent number: 11674557Abstract: A brake assembly for an electric motor includes: a magnetic body, a winding, a bolt, a housing part with a brake surface, an armature disk, a brake pad plate, a shaft, a spring part, and a first bushing. The housing part is connected to the magnetic body by the bolt, with a positive fit in at least the circumferential direction. The first bushing is accommodated in a second bushing. The spring part supported on the housing part presses the first bushing and/or the second bushing toward the magnetic body. The radial clearance range covered by the armature disk includes the radial clearance range covered by the second bushing, and the axial region covered by the armature disk includes the axial region covered by the second bushing.Type: GrantFiled: April 25, 2019Date of Patent: June 13, 2023Assignee: SEW-EURODRIVE GMBH & CO.
