Patent ID: 8587176

Claim:
A salient pole concentrated winding stator for an electric motor, comprising: an annular stator core including a plurality of teeth arranged at predetermined intervals in a circumferential direction and projecting radially; and a plurality of coils wound around the teeth such as to have different phases on the teeth adjacent in the circumferential direction, wherein each of the coils includes a first winding end located on a radial outer side at one axial end of the stator and a second winding end located on a radial inner side at the one axial end of the stator, and at least one of the first winding end and the second winding end extends across the coil of a different phase in the circumferential direction, the plurality of coils being configured such that the conductive wires are covered with insulation coatings, wherein an end portion of the first winding end of one of the coils of the same phase that are adjacent in the circumferential direction is directly joined to an end portion of the second winding end of the other coil to form a joint portion without using an electric-power collection/distribution member, wherein the insulation coatings are respectively removed from the end portion of the first winding end and the end portion of the second winding end, and wherein the joint portion is covered with an insulating material, and an end surface of the first winding end and an end surface of the second winding end are arranged inside of the insulating material.
