An electronically commutated motor contains a rotor position determination, which detects a surface at which the rotor and stator poles ( through through ) diametrically oppose one another. The total surface is taken into consideration in the position determination. The pole angles (&bgr; , &bgr; ) of the stator and rotor poles ( through through ) are each set to values at which a rotor rotation results in a surface change.

Electronically-commutated motor

An apparatus for detecting the angular position of a first rotatable body ( , L) has a number n of uniform angle markings or teeth ( ), with at least two rotatable gear wheels ( ), which respectively have n , n , n , n uniform angle markings or teeth. The angle markings of the at least two rotatable gear wheels ( ) cooperate with the angle markings ( ) of the first rotatable body ( ) in such a way that by detecting the angular positions &thgr;, &psgr; of the at least two rotatable gear wheels ( ), the angular position a of the first rotatable body can be determined. When there are two of the at least two rotatable gear wheels ( ), &brvbar;n -n &brvbar;>1 and (n , n )&equals;1 or n , n are relatively prime and when there are more than two of the at least two rotatable gear wheels, (n , n )&equals;1, where 1&equals;i<N, with N being the total number of the at least two rotatable gear wheels ( ).

Device and method for detecting the relative position of a rotatable body

A steer-by-wire steering system comprised of an electronically regulated steering positioner mounted to the steering gear of the front axle or to both front wheels of a vehicle together with an electronic steering regulator and a feedback actuator. A sensor senses the driver's selected direction from the steering wheel. Road feedback can be relayed to the driver through a feedback actuator via the steering wheel. The loss of road feel caused by the absence of the steering column, which normally strongly influences the driver's directional wish, is recreated by the feedback actuator.
