    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°.

    摘要: Disclosed are a method for operating a piezoelectric drive system (10) used for adjusting movable parts (12, 14), especially in a motor vehicle (13), as well as a piezoelectric drive unit (10) comprising at least one piezo motor (12) that is fitted with at least one piezo actuator (18). At least one frictional element (30) of the piezo motor (12) makes it possible to generate a relative movement in relation to a frictional surface (14) located across from the frictional element (30). The at least one piezo actuator (18) is triggered with an excitation signal (93) by means of an electronic unit (42). A response signal (130) of the drive system (10) is detected using the at least one piezo actuator (18), a change in the load of the drive system (10) being recognized as a result of a change in the response signal (130).
