A motor housing () has a shaft section to receive a motor shaft () and a motor section to receive motor electronics () and motor windings (). The shaft section and the motor section are separated from each other in a sealed manner by a separating pot () arranged in the motor housing (). A metal ball bearing pot () with a ball bearing () is arranged in the separating pot. The ball bearing pot () lies indirectly against a motor housing section that is connected to the outer surroundings, via the separating pot (). Thus, the motor housing functions as a cooling body. Accordingly, heat generated by the ball bearing () during operation is dissipated onto the motor housing and the outer surroundings, via the ball bearing pot () and the separating pot ().

A stator device with a plurality of windings, on a winding carrier, that electromotive interaction with a rotor. The windings are parallel to one another and to the center axis. The windings can be individually electrically contacted with winding terminals of a winding wire. The windings are assigned to at least two disk-shaped and/or ring-shaped electrically conductive interconnection rings so that they are electrically insulated from one another. The winding terminals are connected using the interconnection ring assigned to this terminal polarity (U; V; W) for external permanent common contact by welding hooks formed on the radial inner side on the interconnection ring. A ring-shaped deflection disk, with deflection pins, is provided in the axial direction on the interconnection end disk.
