Motor

An armature includes a core having a plurality of teeth, which are radially formed with a rotation axis as the center, a plurality of coils where each coil is wound around each set of teeth containing at least two teeth. The plurality of coils have a plurality of inside coils placed on a rotation axis side of the teeth and a plurality of outside coils placed outside the inside coils. The plurality of inside coils are circularly arranged so that inside coils adjacent to each other are not wound around the same tooth. The plurality of outside coils are circularly arranged so that outside coils adjacent to each other are not wound around the same tooth. The outside coils are wound around a second set of combinations of teeth, which are different from a first set of combinations of teeth around which the inside coils are wound.
