The invention relates to a laundry treatment apparatus like washing machines, laundry dryers or a washer-dryers with a rotatably mounted drum ( ) with an at least approximately horizontal axle and with a drive motor ( ) structured as a synchronous motor ( ) energized by permanent magnets arranged on the drum ( ) shaft, the stator ( ) of the motor ( ) being provided with a winding ( ) which is energized by a converter. In order to optimize the motor in such machines in respect of energy consumption, noise development and costs it is proposed to design the winding ( ) as a single pole winding, whereby the number of stator poles ( ) and of the magnet poles ( ) is different, and to utilize a frequency converter ( ) as the converter the output voltage of which being set such the continuous currents are generated in all winding strands.
