Abstract
The invention relates to an electric motor/gear mechanism unit including a housing, an iron-free rotor winding rotatably arranged in the interior of the housing, a collector connected to the rotor winding, a rotor shaft extending through the collector, and a gear mechanism which is connected to the rotor shaft and which has an output shaft. The present invention is so conceived that the gear mechanism is produced from a non-magnetic material and arranged in the interior of the rotor winding.
