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.

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:
After a winding machine connects a winding wire to a terminal pin, a slackening member is moved in a substantially horizontal direction substantially orthogonal to a direction of a terminal block being extended so as to be located on an orbit of the winding wire. Then, a led part of the winding wire radially between the terminal pin and teeth is extended to the teeth while in contact with a curved surface of a tip of the slackening member. That is, the led part is extended while bent in the substantially horizontal direction. After the winding wire is wound around the respective teeth, the slackening member is moved out of the orbit.
摘要:
In an armature for a brushless motor, a gap is provided between an inner circumferential surface of a cylinder portion of a cover and an outer circumferential surface in a radial direction of the armature. A plurality of non-magnetic spacers having a predetermined distance therebetween are provided in a circumferential direction so as to make contact with the inner circumferential surface of the cylinder portion and the outer circumferential surface of the armature.

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.

A resolver includes a terminal block having a plurality of terminals integrally formed therein. Each of the terminals has a conductive wire connecting portion arranged to allow a conductive wire of a resolver stator to be fixed thereto and a lead wire connecting portion which allows a lead wire to be connected thereto. Ultrasonic welding is carried out to join the lead wire connecting portion and a connecting end of the lead wire.
