    • A drive unit for generating an oscillatory motion for small electric appliance, for example a toothbrush or razor. The drive unit includes a stator having at least one coil and a first and a second magnet arrangement each having at least one permanent magnet. The drive unit further includes a rotor which is not symmetrical about the axis and has a first and a second radial projection, each extending only over a partial area of the circumference of the rotor and made of a magnetizable material. By positioning the magnet arrangements relative to the radial projections of the rotor, relative assignments between the magnet arrangements and the radial projections are formed in pairs, such that the magnetic interaction between the magnet arrangement and the radial projection of one pair is invariably greater than the magnetic interaction between the magnet arrangement and the radial projection of two different pairs.
    • 用于产生小型电器的振荡运动的驱动单元,例如牙刷或剃刀。 驱动单元包括具有至少一个线圈的定子和分别具有至少一个永磁体的第一和第二磁体布置。 驱动单元还包括转子,该转子不是关于轴线对称的,并且具有第一和第二径向突起,每个突起仅在转子的圆周的部分区域上延伸并由可磁化材料制成。 通过相对于转子的径向突起定位磁体布置,磁体布置和径向突起之间的相对分配成对地形成,使得磁体布置和一对的径向突起之间的磁性相互作用总是大于 磁体布置与两个不同对的径向投影之间的磁相互作用。
