    • The invention relates to a laundry treatment apparatus like washing machines, laundry dryers or a washer-dryers with a rotatably mounted drum (6) with an at least approximately horizontal axle and with a drive motor (10) structured as a synchronous motor (10) energized by permanent magnets arranged on the drum (6) shaft, the stator (16) of the motor (10) being provided with a winding (18) 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 (18) as a single pole winding, whereby the number of stator poles (27) and of the magnet poles (23) is different, and to utilize a frequency converter (104) as the converter the output voltage of which being set such the continuous currents are generated in all winding strands.
    • 本发明涉及一种衣物处理设备,如洗衣机,衣物烘干机或具有可旋转地安装的滚筒(6)的洗衣机干衣机,其具有至少近似水平的轴并且具有被构造为同步电机(10)的驱动马达(10) 通过布置在滚筒(6)轴上的永久磁铁激励,马达(10)的定子(16)设置有由转换器激励的绕组(18)。 为了在能量消耗,噪声发展和成本方面优化这种机器中的电机,建议将绕组(18)设计为单极绕组,由此定子极(27)和磁极(数量) 23)是不同的,并且利用变频器(104)作为转换器,其输出电压被设置为在所有绕组中产生连续电流。
