摘要： 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°.
