摘要： A resolver rotor for a variable reluctance resolver includes a plurality of axially stacked rotor pieces. The rotor pieces are jointly fitted into one body. In the fitting of the rotor pieces, deformed portions are provided between a center of the radial thickness of the resolver rotor and a side surface thereof which is opposite to a stator-side surface thereof. The number of deformed portions is the same as that of projecting poles of the resolver rotor. The deformed portions are arranged at circumferential positions of peaks of the respective projecting poles. At those positions, concave portions are provided on the side surface to receive deformations caused by fitting the rotor pieces together. Thus, the stator-side surface of the resolver rotor is less affected by fitting of the rotor pieces together, preventing a reduction in the detection accuracy of the resolver.

摘要： In a resolver of a motor, a plurality of wires forming a plurality of coils arranged at a resolver stator portion are arranged at a wiring surface which is arranged at a terminal block of a connector portion and extends between an annular shape surface arranged substantially perpendicularly to a central axis at a core back of an insulator and a plurality of terminal pins, and are connected to a control unit via the terminal pins. Each of the wires of the resolver includes a slackened portion formed at a portion thereof between corresponding terminal pins and corresponding coils. The slackened portion is accommodated in a groove portion arranged at the wiring surface of the connector portion in order to minimize the possibility of damaging the wire improving reliability of the connection between the terminal pin and the coil.

摘要： A second bracket part for holding a resolver stator of a resolver as position detecting means is inserted in an opening hole in a first bracket part. An expanded part formed in the second bracket part and the opening hole in the first bracket hole are connected to each other with a fixing member. A through hole in which the fixing member for the expanded part is inserted has a circular arc shape. By reducing the fixing strength of the fixing member, the second bracket part can be made movable in the circumferential direction.
