Manufacturing method of rotary electric machine and rotary electric machine

A manufacturing method of a rotary electric machine including a stator provided with a stator iron core, which is cylindrical and in which a plurality of slots are formed in a circumferential direction on an inner circumferential surface, and coils of a plurality of phases that are each inserted into the plurality of slots, and a movable element provided with a movable element iron core that is supported in a rotatable manner relative to the stator and at least a pair of movable element magnetic poles that is provided in the movable element iron core,

• the method comprising:
• a split flux coil formation step of, for each phase, forming split flux coils in which the coils of the plurality of phases are divided into a plurality of the split flux coils from a conducting wire;
• a coil setting step of performing insertion in a lamellar form between blades of a coil insertion machine by overlapping the plurality of split flux coils of each phase in a formation direction of the blades, the coil insertion machine being provided with a plurality of the blades, which are rod-shaped and disposed spatially separated from one another around a circumference, and a pusher, which is disposed on the inner side of each blade so as to face an inner side portion of each blade, and which moves in the formation direction of the blades;
• a stator iron core setting step of setting the stator iron core in the coil insertion machine so that a position of each of the slots conforms with a position of a gap formed between the blades;
• and
• a split flux coil collective insertion step of performing insertion in a lamellar form by pressing, with a plurality of split flux coils that are respectively inserted between the blades and that are on the pusher side, split flux coils that are closer to the stator iron core side than the plurality of split flux coils that are on the split flux coils that are on the pusher side as a result of moving the pusher to the stator iron core side, and sequentially overlapping the plurality of split flux coils of each phase in each slot in a simultaneous manner.
