ELECTROMECHANICAL STEERING BOOSTER AND STEERING BOOSTER ELECTRIC MOTOR Russian patent published in 2006 - IPC B62D5/04 H02K21/16 

FIELD: automotive industry; steering systems of automobiles.

SUBSTANCE: invention is designed for reducing effort on steering wheel. Stator of electric motor is provided with magnetic circuit with n salient poles and rotor, with n-2 poles in form of permanent magnets. Three-phase winding of stator contains coils arranged in six equally alternating phase zones, one coil for pole, several coils belonging to one phase in each phase zone. Winding coils in phase zones belonging to one phase are connected In parallel aiding. Inlet and outlet shafts arranged in booster housing are interconnected by torsion bar being sensitive element of torque sensor and coupled with steering wheel and steering mechanism by other ends. Rotor of electric motor is installed on outlet shaft. Stator winding controllable supply, rotor position pickup and control unit are provided. Inputs of the latter are connected with outputs of torque sensor and rotor position pickup, and output is connected to control input of said supply source. Group if inventions makes it possible to improve manufacturability of electric motor and steering booster as a whole.

EFFECT: improved operating characteristics, safety and comfortability of steering.
