Abstract:
    The variable reluctance type angle detector has a stator and a rotor. The rotor is provided rotatably with respect to the stator. The stator has a plurality of tooth members disposed in a circle. An excitation wire and an output wire are wound around the tooth members. The rotor has such a shape that a gap permeance with respect to the stator varies in a sine wave fashion with respect to an angle theta. The stator is provided with an end insulator for insulating and covering the tooth members. The end insulator is provided with partitions each insulating and separating the excitation wire from the output wire wound around each of the tooth members in a radial direction of the stator.
