Abstract
A drive device for a front-loading washing machine having a washing liquid-container with a rear wall, an at least substantially horizontal shaft having an outer end, and a laundry drum supported overhung on the shaft, includes a flat motor mounted at the rear wall of the washing liquid container for directly driving the shaft. The flat motor has a stator connected to the rear wall of the washing liquid container or to a stiff carrier part mounted at the rear wall of the washing liquid container. The stator has a central bearing sleeve for the shaft. The flat motor has a rotor with a peripheral portion, a bell-like flange at the peripheral portion facing the washing liquid container, a hub centrally fastened to and encompassing the outer end of the shaft, a plurality of openings between the hub and the peripheral portion, magnetizable poles distributed at the inner periphery of the bell-shaped flange, lamination stacks distributed at the stator and disposed opposite to and spaced apart from the rotor defining a minimum air gap, and exciter windings received by the lamination stacks.
