Abstract

The invention relates to an electric motor comprising a rotor, a stator () and an electronic housing (), the installation space () of which accommodates electrical/electronic components (). At least part of these components () is seated on a printed circuit board (). A fan wheel () is located inside the installation space. It is arranged and designed in such a manner that it generates a cooling circuit stream in the installation space (), in which the air is drawn in centrally from the fan wheel () and is discharged approximately radially to the outside. As a result of this defined cooling air stream, the components () are evenly cooled in the installation space (). The fan wheel () consists at least of a base body which comprises blades () located between a cover disc () and a base disc (). In this way, the fan wheel () generates a directed cooling air stream for cooling the heat-generating components.
