Abstract

Official abstract text for this publication.

An electric drive for a domestic appliance includes a rotor and a shaft. An axial bearing retains the rotor on the shaft. The axial bearing has an axle hole, a multi-sided outer contour and an end face having a recess running centrally through the axle hole. The rotor includes a bearing seat that has a multi-sided inner contour corresponding to the multi-sided outer contour. The bearing seat has lateral notches. The recess ends at opposite ones of the lateral notches on opposite sides of the end face.

First claim

Opening claim text (preview).

The invention claimed is: 1. An electric drive for a domestic appliance, comprising: a rotor; a shaft; an axial bearing for retaining the rotor on the shaft, the axial bearing having an axle hole, a multi-sided outer contour and an end face having a recess running centrally through the axle hole; the rotor including a bearing seat having a multi-sided inner contour corresponding to the multi-sided outer contour, the bearing seat having lateral notches; said recess ending at opposite ones of said lateral notches on opposite sides of said end face. 2. The electric drive as claimed in claim 1 , wherein the bearing seat has an outer contour in the shape of a circle. 3. The electric drive as claimed in claim 1 , wherein the bearing seat is embodied in the form of individual segments, which are arranged annularly with a distance between two adjacent segments in each instance. 4. The electric drive as claimed in claim 1 , wherein a base surface of the bearing seat has a curved segment. 5. The electric drive as claimed in claim 1 , wherein the axial bearing is arranged with play in the bearing seat.
