Abstract
Provided is a manufacturing method for a stator coil in which end portions of one-side conductor segments inserted into slots from the side of one end in an axial direction of a stator core and end portions of other-side conductor segments are connected to each other through coupling members inside the slots. The method includes: 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 the inner circumferential side of the stator core; connecting the end portion of the one-side conductor segment and the end portion of the other-side conductor segment to each other; and executing the pressing in and the connecting sequentially from the outer circumferential side of the stator core.
