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.
