The invention relates to a stator for an electric motor comprising several poles (P) that are directed inwards towards the motor axis () and that surround a rotor (), each pole (P) being provided with one winding (L) and the coils of the windings (L) being wound around the poles (P) one after the other without interruption. The stator () contains at least three pole groups (n), having at least three poles (P) and each group having the same number of poles (P). The windings (L) run out from the end face at least at the respective beginning and end of a pole group and are contacted there in such a way that the windings (L) associated with each pole group contain their own connection pair (U-U', V-V&#x2032;, W-W&#x2032;) and one connection (U&#x2032;, V&#x2032;, W&#x2032;) of each of these connection pairs is connected to a star point (Y) on the end face of the stator (). The windings (L) are wound around the poles (P) one after the other with an alternating winding direction (WR), a single pole (P) having a winding (L) with the same winding direction as the preceding winding (L) of the preceding pole group (n) at an individual transition point between two pole groups (n).

Stator winding for an electric motor

A rotational speed superimposing device for a vehicle steering system has an input shaft with an output shaft, which is oriented toward the input shaft in the axial direction thereof, and has a supporting arrangement, which positions the input shaft and the output shaft so that they are at least, in part, rotationally mounted. An auxiliary drive provided with a rotor, which is connected in a rotationally fixed manner to a wave generator, such as an oval disk on whose periphery an external toothed flexible ring is directly or indirectly mounted, this external toothing engaging in an internal gear at least at two opposite peripheral points. The supporting arrangement is fixed to the vehicle body. The output shaft is connected in a rotationally fixed manner to the internal gear, and the input shaft is connected in a rotationally fixed manner to the external toothed flexible ring. The input shaft and the output shaft are mounted so they freely rotate independently of one another.

Device for superimposing rotational speeds for a steering system

An electric servo steering arrangement and method for motor vehicles with a rotational angle sensor configuration for acquisition of the position of the steering movement has a support plate rotating relative or corresponding to the steering movement, with at least one code track and at least one stationary sensor acting on the code track. The code track is disposed about the rotational axis of the support plate and has markings for generating a sequentially changing bit pattern and the 360&#xb0; of the circumference divided by the number of markings on the circumference defines a clock angle (&#x3b2;). The bit pattern is determined by a phase-shifted disposition of markings with respect to the fixed division of the clock angle (&#x3b2;).
