Manufacturing method for stator coil

A manufacturing method for a stator coil in which end portions of one-side conductor segments that are inserted into slots from a side of one end in an axial direction of a stator core having a plurality of the slots, and end portions of other-side conductor segments that are inserted into the slots from a side of the other end in the axial direction of the stator core, are connected to each other through coupling members inside the slots, the coupling members being mounted either to the end portions of the one-side conductor segments or to the end portions of the other-side conductor segments and inserted into the slots along with the end portions of the one-side conductor segments or the end portions of the other-side conductor segments,

• the manufacturing method comprising:
• partially inserting the one-side conductor segments or the other-side conductor segments into the slots;
• after the inserting, pressing in the one-side conductor segment or the other-side conductor segment in an insertion direction in a state where the end portion of the one-side conductor segment or the end portion of the other-side conductor segment, or an end portion of the coupling member has been moved toward an inner circumferential side of the stator core;
• after the pressing in, connecting the end portion of the one-side conductor segment and the end portion of the other-side conductor segment to each other through the coupling member;
• and
• executing the pressing in and the connecting sequentially from an outer circumferential side of the stator core.
