    • A washing machine includes a tub having a bottom wall and a laundry drum having an at least approximately horizontally disposed shaft. A drive device for the washing machine includes a flat motor for directly driving the laundry drum shaft. The motor includes a rotor having a rotor shaft and a stator connected to the bottom wall of the tub instead of to a rigid carrying part with a bearing sleeve for the laundry drum shaft. The stator has a central bearing sleeve with one or two spaced-apart rolling bearings for the rotor shaft. The rotor shaft has an end facing the laundry drum with a concentric bore for receiving the laundry drum shaft. The bore reaches approximately into a plane of the drum-side rolling bearing. The rotor has a bell fastened to an outer end of the rotor shaft with an edge pointing toward the tub. Magnetizable poles are distributed on the inner periphery of the edge and across airgaps oppose a number of exciting windings distributed circularly on the stator. The drive for the horizontally mounted laundry drum has a cost-effective construction, the motor may be fully preassembled at the factory where it is manufactured and the stator may replace an otherwise conventional star carrier for the tub.
