Adjustment system for motor vehicle, has control device designed to control drive motor depending on drive current ripple, where windings of motor coil have winding pitch corresponding to half the number of slots of motor reduced by two
The system has a control device (100) including measuring resistor (120) and microcontroller (140) for measuring a ripple of a drive current flowing through a mechanically commutated drive motor (20), where the ripple is caused by mechanical commutation. The control device is designed to control the drive motor depending on the measured ripple. A number of windings of a coil of the drive motor include a winding pitch corresponding to half the number of slots of the drive motor reduced by two.
