Abstract
An electric motor having a housing, having an armature, having an armature shaft supported in two slide bearings, where one of the slide bearings axially displaceably receives the armature shaft and the other slide bearing limits an axial displaceability of the armature shaft by the disposition of a stop disk between a slide bearing bush of the slide bearing and the armature, by the disposition of an axial stop, in the form of a stop ring pressed over one end of the armature shaft. The armature shaft end protrudes out of the housing and is intended for carrying and driving a fan wheel that has a hub which is located adjacent the particular a slide bearing that receives only radial forces. The armature shaft end that carries the fan wheel is associated with the particular slide bearing that is designed as a bidirectionally acting axial bearing, and the hub of the fan wheel is brought so close to a face-end running face of the slide bearing bush that this hub on its face end forms an axial stop of the axial bearing. As a result, a special stop ring is unnecessary.
