Abstract: The invention relates to a stator for an electric motor comprising several poles (P) that are directed inwards towards the motor axis (2) and that surround a rotor (1), 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 (20) 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?, W-W?) and one connection (U?, V?, W?) of each of these connection pairs is connected to a star point (Y) on the end face of the stator (20).

Abstract: 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.

Abstract: 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° of the circumference divided by the number of markings on the circumference defines a clock angle (?). The bit pattern is determined by a phase-shifted disposition of markings with respect to the fixed division of the clock angle (?).

Abstract: An electric motor has an internal ferromagnetic rotor ring and an external stator. Circumferentially distributed cutouts in the rotor receive rectangular permanent magnets each having a width b and height h and the rotor ring is divided into rotor poles. The height h forms the longer side of each magnet and is radial to the motor axis. The magnets are magnetized in the width b direction with like poles oriented toward one another. A magnetic clearance is located between adjacent magnets for each inner portion of a rotor pole. The clearance does not contain magnetic material and in a center region of the rotor poles one support web connects an inner support ring with the particular rotor pole to provide mechanical support.

Abstract: A power-assisted steering system is disclosed. A motor is coupled by a motor shaft and a clutch to a worm shaft, which in turn engages a worm wheel. The worm shaft and the worm wheel are mounted in the gearbox housing. The distal end of the worm shaft is mounted in a bearing, and a proximal end of the worm shaft is mounted to the clutch. This construction permits inclusion of a partial housing coupled to the gearbox and enclosing the motor. Both ends of the motor shaft may be mounted in the partial housing motor bearings, and the partial housing may be displaceable with respect to the gearbox housing. Further, the motor may be locationally adjustable with the partial housing in a radial direction defined by an axis of rotation of the motor shaft.
