Abstract:
1. A manufacturing method of a resolver including a stator portion having a plurality of teeth arranged in a circumferential direction centered about a central axis, a core back supporting the teeth from radially outside of the teeth, an insulator covering a surface of each tooth, and a connector portion formed integrally with the insulator having a terminal block protruding outwardly from the stator portion in a radial direction and a plurality of terminal pins protruding from the terminal block, the method comprising the steps of: a) forming the stator portion and the connector portion at which a wiring surface arranged above the terminal block, extending from an annular shape surface substantially perpendicular to the central axis and arranged at the core back of the insulator to the terminal pins, includes a groove portion; b) winding one end of a wire, whose other end is wound around either one of the terminal pin and the tooth, around either one of the corresponding terminal pin and the corresponding tooth detouring around a jig arranged at a shortest distance between the either one of the terminal pin and the tooth and the either one of the corresponding terminal pin and the corresponding tooth; c) forming a slackened portion in the wire by removing the jig from its original position; and d) accommodating the slackened portion at the groove portion of the connector portion.
