<p>PROBLEM TO BE SOLVED: To suppress torque reduction, further, to improve torque ripple and to reduce a coil eddy loss.SOLUTION: A motor includes a stator core, a first insulator, a coil and a second insulator. The first insulator is fitted to teeth and fixed on a side face of the teeth in a circumferential direction and includes: a flange part extending around an outer circumference of roots of the teeth; and a main body part extending from the roots of the teeth to distal ends and covering the outer circumference of the teeth. The coil is wound around the outer circumference of the teeth via the first insulator. The second insulator is fitted to the teeth and fixed to the first insulator and includes: an insulator part extending around an outer circumference of the distal ends of the teeth while holding the coil between the insulator part and the flange part of the first insulator in a radial direction of the stator core; and a magnetic substance part extending in a circumferential direction of the stator core from side faces of the distal ends of the teeth in the circumferential direction in contact with side faces of the distal ends of the teeth in the circumferential direction.</p> |
