Abstract
A rectangular wire is wound on a stator core having a plurality of teeth and a plurality of slots. A plurality of rectangular wire elements is provided by cutting a rectangular wire into a predetermined length and bending into a substantial U-shape. A plurality of rectangular wire pieces configured to form a coil by connecting predetermined end portions of the rectangular wire elements is molded as a sub-assembly. Each of the plurality of the rectangular wire elements is inserted into a predetermined pair of the slots from a first end face of the stator core such that the respective end portions of the rectangular wire elements project from a second end face of the stator core. The rectangular wire pieces of the sub-assembly are fixed to the end portions of the rectangular wire elements, thereby manufacturing a stator coil having compact coil ends easily.
