Abstract

A motor, comprising an electronics housing, a stator having a stator bushing, and a rotor. The motor can be fastened to a fastening wall by means of the stator bushing. The motor according to the invention has an air conducting element and an air conveying element. The air conveying element is connected to the rotor in a rotationally fixed manner. The air conducting element surrounds the stator bushing and forms a flow space between the air conducting element and an outer circumference of the stator bushing. The flow space is open on the side of the electronics housing in the direction of the fastening wall through at least one flow gap. The air conducting element opens with an intake opening via a sealing gap in a rotor-side throughflow opening of the air conducting element.
