Abstract
A stator structure includes a stator core, insulators, a coil, and shield plates. The stator core includes a plurality of teeth extending from a body part of the stator core in a radial direction thereof. The body part is formed in an annular shape. The insulators cover the teeth from both sides in an axial direction of the stator core. The coil is wound around each of the teeth with the insulators interposed therebetween. The coil covers cover the coil from both sides in the axial direction. Each of the coil covers is formed in an annular shape. The shield plates are attached to the stator core from both sides in the axial direction of the stator core with the respective coil covers interposed therebetween.
Claims6
A stator structure comprising:
- a stator core that includes a plurality of teeth extending from a body part of the stator core in a radial direction thereof, the body part being formed in an annular shape;
- insulators that cover the teeth from both sides in an axial direction of the stator core;
- a coil that is wound around each of the teeth with the insulators interposed therebetween;
- coil covers that cover the coil from both sides in the axial direction, each of the coil covers being formed in an annular shape;
- and
- shield plates that are attached to the stator core from both sides in the axial direction of the stator core with the respective coil covers interposed therebetween, wherein
- first through holes are formed in the coil covers, the first through holes being along the axial direction of the stator core,
- second through holes are formed in the shield plates, the second through holes being along the axial direction of the stator core, and
- the insulators are provided with pins, the pins being formed along the axial direction of the stator core in an erected manner and having respective distal end parts protruding from the second through holes in a state where the pins are inserted into the first and second through holes, and the protruded distal end parts being fixed to the shield plates.
A resolver comprising:
- a rotor;
- and
- a stator structure, wherein the stator structure includes:
- a stator core that includes a plurality of teeth extending from a body part of the stator core in a radial direction thereof, the body part being formed in an annular shape;
- insulators that cover the teeth from both sides in an axial direction of the stator core;
- a coil that is wound around each of the teeth with the insulators interposed therebetween;
- coil covers that cover the coil from both sides in the axial direction, each of the coil covers being formed in an annular shape;
- and shield plates that are attached to the stator core from both sides in the axial direction of the stator core with the respective coil covers interposed therebetween, wherein
- first through holes are formed in the coil covers, the first through holes being along the axial direction of the stator core,
- second through holes are formed in the shield plates, the second through holes being along the axial direction of the stator core, and
- the insulators are provided with pins, the pins being formed along the axial direction of the stator core in an erected manner and having respective distal end parts protruding from the second through holes in a state where the pins are inserted into the first and second through holes, and the protruded distal end parts being fixed to the shield plates.
