ABSTRACT:
A washing machine includes a laundry drum mounted through an at least approximately horizontally disposed shaft within a bearing sleeve of a rigid star carrier attached to a bottom wall of a tub. A drive device for the washing machine can be mounted on the rear side of the tub. The drive device includes a flat or pancake motor having a stator carrying part with exciting windings and a rotor with magnetizable poles, for driving the laundry drum directly. The stator carrying part and the rotor of the motor are releasably connected to one another, with the stator carrying part in a position relative to the rotor corresponding to an operating position, for a duration of transport of the motor until a final mounting on the bottom wall of the tub. Therefore, the motor can be delivered, ready-preassembled and tested, to the factory manufacturing washing machines. The motor can be installed there in washing machines in a simplified way, without the need for further action on the washing machine when the motor is being installed, which could put at risk adherence to tolerances necessary for the motor to operate properly.
