Patent ID: 8051943

Claim:
A steering wheel electromechanical booster, comprising: a body, wherein there are positioned input and output shafts, which are interconnected with the aid of a torsion bar, which is embodied in the form of a torque sensor sensing element, and are linked with the steering wheel and a steering mechanism by the other end thereof, an electric motor, comprising a stator with a magnet core, having n pronounced poles, and with a three-phase winding, which is accomplished with coils, that are placed in six equal alternating phase areas in such a manner that one area is assigned to one pole, and with several coils, belonging to one phase in each phase area, and a rotor with n−2 poles, which are embodied in the form of permanent magnets, therewith, the rotor is mounted on the output shaft, a controllable source for supplying the stator three-phase winding of the electric motor, a rotor position sensor of the electric motor and a control unit, inputs of which are connected to the outputs of the torque sensor and the electric motor rotor position sensor, but the output of which is connected to the control input of said supplying source, wherein the coils of the electric motor stator three-phase winding in the phase areas, belonging to one phase, are connected in a parallel aiding configuration.
