PROBLEM TO BE SOLVED: To reduce a windage loss applied to a rotor during high-speed rotation.;SOLUTION: A stator structure of one embodiment includes a stator core, an insulator, and a plurality of coils. The stator core has a plurality of teeth extended from an annular body portion in a radial direction. The insulator covers both sides of the stator core in an axial direction. The plurality of coils are wound around the plurality of teeth, respectively, via the insulator. A gap is formed in a circumferential direction between distal end portions of adjacent teeth. The insulator has a cover portion closing the gap.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
