ABSTRACT:
A method for manufacturing a stator of a motor having a coil wound on a ring-shaped core having a plurality of slots. The coil is first preformed into a chevron-shape before being mounted on the core so that the chevron-shaped coil comprises front coil end portions positioned within the inner diameter of the core, slot coil portions positioned at the diameter of the slots and having substantially the same configuration as the slots, rear coil end portions positioned between the slot coil portions, and transition coil portions positioned between the front coil end portion and the slot coil portions. This preformed coil is inserted into the core from its end face and the front coil end portions are bent toward the outside of the inner diameter of the core.
