Abstract
A plurality of slots are provided at a stator core. A coil component is produced by winding conductor wires around a forming tool several times. The coil component is cut off at a predetermined part and inserted into a slot so as to cross over the plurality of slots. Then, a coil is formed by connecting the corresponding conductor wires at cut surfaces of the coil component.
Claims4
A motor comprising:
- an armature iron core provided with a plurality of slots each having a cross section of a quadrilateral with exactly one pair of parallel sides;
- and
- a pre-fabricated coil component installed in the plurality of slots of said armature iron core where the cross section of said pre-fabricated coil component is a quadrilateral with exactly one pair of parallel sides, which is substantially the same as the cross section of each of the plurality of slots,
- wherein said pre-fabricated coil component comprises a plurality of conductor wires, each having a rectangular cross section, electrically insulated from each other and includes at least two or more connecting portions where the plurality of conductor wires are cut and connected subsequently in such a way that the plurality of conductor wires are serially connected,
- wherein the at least two or more connecting portions of said pre-fabricated coil component are located outside of the plurality of slots of said armature iron core and are arranged successively adjacent to each other, and
- wherein the cross section of said pre-fabricated coil component includes two or more rows of conductor wires and each of the rows comprises at least two conductor wires so as to form a shape of a quadrilateral with exactly one pair of parallel sides.
