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

An electromotor has an external stator, and a ventilator vessel which is used to produce a cooling air flow for self-ventilation of the electromotor. In order to improve the cooling of an electromotors, it is proposed to use a ventilator vessel to help direct an air flow along the outer surface of the motor housing, through the inside of the housing of the electromotor and through an air gap formed between the motor housing wall and ventilator vessel.

Electromotor

The invention relates to a cooling fan for use in a motor vehicle. To achieve improved cooling of an electric motor it is proposed that the motor housing enclosing the electric motor be used as a heat sink for emitting waste heat into a cooling air flow. The cooling air flow for cooling the electric motor is routed here through the interior of the motor housing and subsequently along the outside of the motor housing over cooling elements in the areas of the air inlet openings and in the area or an air exit gap between fan wheel hub and front part of the motor housing. The cooling air flow is created in this case by the fan wheel hub of the fan wheel driven by the electric motor.
