VEHICLE STEERING ELECTROMECHANICAL BOOSTER Russian patent published in 2010 - IPC B62D5/04 

FIELD: automotive industry.

SUBSTANCE: proposed electromechanical booster comprises housing accommodating two aligned input and output shafts, three-phase motor, stator magnetic core built in booster housing, rotor magnetic core and pickup of moment. Stator magnetic core features salient poles with coils, one coil per one pole. Said coils are arranged in six alternating phase zones. Rotor multi-pole magnetic core features (n-2) poles with excitation from tangentially arranged permanent magnets with their like poles adjoining rotor poles. Moment pickup represents a torsion and torsion angle metre. The former is arranged inside chamber formed by aforesaid input and output shafts. Additional magnetic core is fitted on motor rotor opposite the air gap, via non-magnetic gap comparable with said air gap.

EFFECT: higher efficiency and reliability, improved ergonomic properties.
