Abstract
A rotary position detector includes first and second members, the first member generating a magnetic field which spatially varies around the axis of rotation in a cyclic manner and the second member sensing the generated magnetic field. In response to the generated magnetic field, first and second signals are generated by first and second sensors respectively, which signals vary with the relative angular position of the first and second members and the relative angular position of the first and second members is determined from the first and second signals.
