Abstract
A steering drive for a motor vehicle comprising a steering wheel, a steering column, on which the steering wheel is disposed, a connecting rod, which interacts with the steering column to deflect the wheels of the motor vehicle, an electric motor, which is provided for boosting the steering thrust, as well as a belt drive, the electric motor interacting with the connecting rod via the belt drive. Said electric motor comprises a stator having twelve stator teeth as well as a rotor having ten rotor poles, the rotor poles being spaced apart from each other by an air gap and embodied as sinus poles.

A steering drive (1) for a motor vehicle comprising:
- a steering wheel (2),
- a steering column (3), on which the steering wheel (2) is disposed,
- a connecting rod (4), which interacts with the steering column (3) to deflect the wheels (7) of the motor vehicle,
- an electric motor (5), which is provided for boosting the steering thrust, and
- a belt drive,
- wherein the electric motor (5) interacts with the connecting rod (4) via the belt drive (6), said electric motor (5) comprising a stator (10) including a yoke (57) having grooves (58) into which twelve stator teeth (51) are inserted, as well as a rotor (11) having ten rotor poles (52), said rotor poles (52) are spaced apart from each other by an air gap (53) and are embodied as sinus poles (SIN).
