ABSTRACT:
The present invention refers to a dc motor, in particular a micro dc motor, comprising a shaft and a collector element arranged on said shaft and consisting of a collector plate and a collector which projects from said collector plate beyond the shaft end, the collector element being extended beyond the collector so as to form a shaft section on the side facing away from the collector plate, said shaft section being adapted to have attached thereto an additional component part. In accordance with a preferred embodiment, the dc motor is provided with an incremental angle-position encoder comprising an encoder element, the encoder element being fixedly attached to the collector element, which is extended so as to form a shaft section, and constituting the additional component part.
