Patent ID: 7569964

Claim:
A variable reluctance type angle detector comprising: a stator having a plurality of tooth members disposed in a circle, each of the tooth members having an excitation wire and an output wire wound thereon; a rotor which rotates with respect to the stator and has such a shape that a gap permeance varies in a sine wave fashion with respect to an angle θ; an end insulator provided on the stator for insulating and covering the tooth members; the end insulator has a partition that insulates and separates the excitation wire from the output wire wound around each of the tooth members in a radial direction of the stator; and an excitation wire retaining part retaining a crossover of the excitation wire and an output wire retaining part retaining a crossover of the output wire are formed at a position corresponding to each of the tooth members on the end insulator in a stair-like shape so that the crossover of the excitation wire does not contact the crossover of the output wire.
