摘要： 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.

摘要： The stator includes a stator core having a plurality of slots; and a plurality of windings composed of coil units formed by winding coil strands a certain number of times and having a plurality of straight portions and coil end portions joining the ends of adjacent straight portions, the windings being incorporated into the stator core by inserting the plurality of straight portions into the slots in sequence at intervals of a certain number of slots and allowing the coil end portions to protrude axially outward from the ends of the stator core. Each coil strand has a coil shape composed such that after coming out of a slot, the strand extends in one direction around the circumference so as to be pointed axially outward and away from the end of the stator core, then doubles back towards the radially inner edge, extends in the one direction around the circumference so as to approach the end of the stator core, and enters a slot three slots away from the slot out of which the core strand came in the one direction around the circumference, and the strands are arranged so as to overlap around the circumference at the turn around portion of the coil shape and its vicinity.
