<p>PROBLEM TO BE SOLVED: To provide a motor in which thickness of an insulator is reduced.SOLUTION: An armature comprises: an insulator which covers a stator core; a coil in which a conducting wire is wound around a magnetic pole teeth through the insulator; and a crossover which is arranged between adjacent teeth in a circumferential direction to electrically connect one coil with the other. A core back insulation part 262 comprises: a plurality of crossover guide walls 2624 which is protruded from a surface covering the core back between a casing and the crossover; a plurality of crossover holding parts 2626 which supports the crossover at the inside in a radial direction of the crossover guide wall by an external surface in the radial direction, and is protruded from the surface covering the core back; and a plurality of coil guide walls 2623 which faces an outer end of the coil and the radial direction at the outside in the radial direction of the teeth, and is protruded from the surface covering the core back. A top edge of the crossover guide wall 2624 at the central part is arranged at a position lower than a top edge of the crossover holding part in an axial direction.</p> |
