Electromotive auxiliary drive for vehicles, for example a windscreen wiper drive or wiper motor, with a shaft driven circularly in a direction of rotation when the drive is switched on and with a sensor arrangement for recognition of the rotational position of the shaft, wherein the sensor arrangement presents at least one permanent magnet and at least two sensor elements which with a rotating shaft (1) and a thereby induced relative movement between the at least one permanent magnet and the sensor elements, deliver phase-displaced or time-displaced output signals through interaction with the magnetic field of the permanent magnet.
