    • The invention relates to a drive and evaluation unit for displacing an object to be displaced, particularly for raising and lowering a side window in a motor vehicle. The drive includes a commutator motor with a stator having two diametrically opposed permanent magnets. The magnets have cross-sectional shapes of a respective peripheral contour segment, having a radial inner peripheral contour segment which encompasses an armature over a respective inner peripheral angle. The armature is provided with ten grooves spaced around its periphery for holding armature windings that are configured as lap windings. The evaluation unit includes a device for determining the rotational position of the armature by evaluating the ripple count of the armature current. According to the invention, the armature windings are configured as short pitch windings, and the inner peripheral angle of the radial inner peripheral contour segment of at least one of the magnets is between 101° and 111°.
    • 本发明涉及一种用于移动待移动物体的驱动和评估单元,特别是用于升高和降低机动车辆中的侧窗。 该驱动器包括具有定子的换向器马达,该定子具有两个直径相对的永磁体。 磁体具有相应的周边轮廓段的横截面形状,其具有在相应的内圆周角度上包围电枢的径向内周轮廓段。 电枢具有围绕其周边隔开的十个凹槽,用于保持配置为搭接绕组的电枢绕组。 评估单元包括通过评估电枢电流的纹波计数来确定电枢的旋转位置的装置。 根据本发明,电枢绕组被配置为短节距绕组,并且至少一个磁体的径向内周轮廓段的内圆周角在101°和111°之间。
