Abstract: The invention relates to a drive device for a vehicle rearview mirror, the positioning of which is achieved by means of a worm gear mounted by means of a coupling part in a single bearing, which is provided with an annular collar that engages in an upper annular slot of the coupling part. The intention is to improve the retaining force of the bearing.

Abstract: A drive device for a motor vehicle rear-view mirror comprises a spur gear which may be driven by the shaft of an electric motor, and which is supported by a spherical bearing. The rear-view mirror is carried by a drive plate which is journaled for spherical movement about a spherical seat spaced laterally of the spur gear. A hollow pin extends from said drive plate, being non-rotatably connected for articulation therewith, the hollow pin having external threads. A guide mandrel extends from the spur gear into the hollow pin in sliding relationship, and elastically yieldable snap hooks extend from the spur gear outwardly of the guide mandrel and the hollow pin, and have hook parts for threadedly engaging the threads on the hollow pin.

Abstract: A method of manufacturing and winding stator core stacks intended for electric motors with internal rotors. Identical sectors are punched and stacked from a sheet metal strip and have spaced pole shoe elements extending radially from a flux return element or core with their free ends projecting inward. The pole shoe elements are given a winding. During the punching process, the pole shoe elements and the flux return element or core are separated from one another and stacked individually, the pole shoe elements being held by an inner ring also punched from the sheet metal strip. Thereafter, windings are applied and finally the wound pole shoes are assembled with the return element to form the stator.The process is especially suitable for manufacturing stators for low-power and miniature motors (less than 1 kW).
