    摘要: An apparatus for detecting the angular position of a first rotatable body (10, L) has a number n of uniform angle markings or teeth (11), with at least two rotatable gear wheels (12, 13, 14, 15), which respectively have n1, n2, n3, n4 uniform angle markings or teeth. The angle markings of the at least two rotatable gear wheels (12, 13, 14, 15) cooperate with the angle markings (11) of the first rotatable body (10) in such a way that by detecting the angular positions &thgr;, &psgr; of the at least two rotatable gear wheels (12, 13, 14, 15), the angular position a of the first rotatable body can be determined. When there are two of the at least two rotatable gear wheels (12, 13; 12, 14; 12, 15; 13, 14; 13, 15; 14, 15), ¦ni-nj¦>1 and (ni, nj)=1 or ni, nj are relatively prime and when there are more than two of the at least two rotatable gear wheels, (ni, nj)=1, where 1=i

    摘要: An electronically commutated motor contains a rotor position determination, which detects a surface at which the rotor and stator poles (10 through 15; 17 through 20) diametrically oppose one another. The total surface is taken into consideration in the position determination. The pole angles (&bgr;S, &bgr;R) of the stator and rotor poles (10 through 15; 17 through 20) are each set to values at which a rotor rotation results in a surface change.
