Abstract: A motor includes a stator having a stator core. The stator includes a coil connection body of one phase having a plurality of coils connected with each other; at least one of the coils has an electrical resistance set to be different from an electrical resistance of another of the coils. The stator also includes a coil connection body of another phase having a plurality of coils connected with each other; at least one of the coils has an electrical resistance set to be different from an electrical resistance of another of the coils. Moreover, the coil connection body of the another phase has a combined resistance set to be equal to a combined resistance of the coil connection body of the one phase.

Abstract: A stator includes an armature core having an annular shape, coils, and an insulator. The coils are arranged along the armature core. Each of the coils is a wound conductive winding. Each of the coils includes a pair of facing portions disposed to be aligned in a circumferential direction with a predetermined interval therebetween. The first and second facing portions of each of the coils constitute intermediate portions of the corresponding one of the coils. Each of the coils includes a pair of first and second coil end portions that link the facing portions to each other. The insulator is arranged between the stator core and the coils. The insulator includes a base comprised of an insulating material, and one or more soft-magnetic members each being comprised of a soft-magnetic material, the one or more soft-magnetic members being contained in the base.
