Patent ID: 7650682

Claim:
A method for manufacturing a stator including a plurality of divisional cores, wherein each divisional core has a tooth, the plurality of divisional cores including a first divisional core and a second divisional core, the manufacturing method comprising: first, arranging a first divisional core and a second divisional core adjacent to each other; second, winding a first coil around a tooth of the first divisional core in a concentrated winding; third, winding a second coil around a tooth of the second divisional core in a concentrated winding, wherein the first coil is connected to the second coil by a connection wire; fourth, arranging the plurality of divisional cores annularly in a state in which the coils are wound around the divisional cores and the plurality of teeth extend radially, the first divisional core and the second divisional core being positioned to face in a radial direction from each when the plurality of divisional cores are arranged annularly, wherein the connection wires are each shaped to be arcuate and bulged in a radially outward direction, and wherein the connection wires project from axial end surfaces of the divisional cores; fifth, forming a plurality of divisional units, with the divisional units each including the first divisional core and the second divisional core; and sixth, forming a stator core by assembling the plurality of divisional units together, wherein the connection wires are moved radially outward and arranged on an axial end surface of the stator.
