Abstract
An angle detector includes a magnetic rotor and a plurality of magnetic stator portions. The magnetic stator portions are arranged separately in an annular stator frame and each magnetic stator portion includes a pair of magnetic stator strips. The periphery of the magnetic rotor is disposed between the magnetic stator strips of each magnetic stator portion. By such a configuration, accurate angle detection can be carried out irrespective of the decentering of a rotary shaft.
