Rotor armature for electric motor for adjusting drive for adjusting element in motor vehicle, has set of armature grooves extending in axial direction and arranged at distance in peripheral direction for armature windings

摘要

The armature (1) has a set of armature grooves (7) extending in an axial direction and arranged at a distance in a peripheral direction for armature windings. An opening (8) is utilized to store the armature on a fixed axis of a rotatably supported armature shaft. A bearing (13) consists of sintered sintering material with soft-magnetic characteristics, and a torque transmission unit (4) exhibits an eccentric cam section (6), where the armature is formed as a single piece. The torque transmission unit and a hub section (3) are interspersed in axial direction by a passage opening (5). An independent claim is also included for an electrical machine formed as a part of an adjusting drive.
