Disk rotor motor, especially for adjustment devices in motor vehicles, has signal generator formed by conducting tracks on rotor or markings integrated into base body in one piece

摘要

The motor has a disc rotor (2) with an essentially disc-shaped base body (20), conducting tracks extending radially on the base body as windings and a device for detecting the rotation angle and/or revolution rate containing a signal generator with a number of markers for generating signals representing rotor rotation. The signal generator is formed by the arrangement of conducting tracks (21,22) on the rotor or by markings integrated into the base body in one piece. An Independent claim is also included for a method of manufacturing an essentially plate-shaped base body for a disc rotor.
