A drive motor, in particular for a fan wheel of a radiator of a motor vehicle, is provided. The drive motor comprising a stator, and a rotor rotating about an axis of rotation relative to the stator, which is driven in cooperation with the stator. Means for generating an air flow for cooling at least one component of the drive motor are arranged on the rotor.

Drive motor having integrated cooling

A brush system for an electric drive unit has a base to which brush system elements are fastened. Strip conductors via which required electrical connections are established are also provided on the base. Furthermore, a flat resistor that is disposed in a resistor housing is inserted into the brush system . The resistor housing is made of a thermally conductive material while being provided with air passage holes.

A liquid pump includes a rotor, a rotor shaft, and a split cage for accommodating the rotor. A stator assembly is situated outside the split cage, and a pump casing has a pump-casing bottom and top part, a flange part, and a plug-in holder. The pump casing accomodates a pump impeller on the shaft, and the pump-casing top part has a plug-in holder. A method for assembling the liquid pump includes axially pressing a bearing into a bearing holder. O-rings are mounted on the split cage. The rotor is axially inserted into the split cage, which is axially pressed into the plug-in holder of the pump casing. The rotor shaft is simultaneously pressed into the pump impeller. The bearing holder has another supporting part and is axially pressed into the split cage. A cap together with the stator assembly are axially mounted onto the plug-in holder. The pump-casing bottom part is connected to the pump-casing top part, preferably with a pump-casing seal in between.
