More Information
Summary:A motor, comprising an electronics housing having integrated motor electronics, a stator, and a rotor. The stator comprises a stator bushing and a laminated stator core having motor windings. The stator bushing is arranged axially between the electronics housing and the rotor. The motor according to the invention has an air-conveying element connected to the rotor in a rotationally fixed manner and at least one axially extending passage opening arranged in the stator bushing. The air-conveying element is arranged axially between the stator bushing and the rotor and has a circumferential axial intake opening on the side of the stator bushing. During motor operation, the air-conveying element sucks in an axial volumetric air flow at an external wall of the electronics housing through the intake opening and the passage opening.
