DEVICE AND METHOD FOR DETECTING THE RELATIVE POSITION OF A ROTATABLE BODY

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 lea...

Zusammenfassung:	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 theta, psi 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
