Method for manufacturing stator, apparatus for manufacturing stator, and stator

摘要

A method for manufacturing a stator includes preparing a stator core having a plurality of teeth, a plurality of coils having a plurality of lead lines, a substrate having a plurality of connecting portions, and a plurality of positioning jigs having restraining portions. The method includes positioning the substrate and the lead lines so that distal portions of the lead lines are separated from the connecting portions in at least one of a radial direction and a circumferential direction. The method further includes inserting the lead lines in the restraining portions, aligning the distal portions of the lead lines with the corresponding connecting portions using the positioning jigs, inserting the lead lines into the corresponding connecting portions, and electrically connecting the lead lines inserted in the connecting portions to the corresponding connecting portions.

1. A method for manufacturing a stator, the method comprising:
preparing an annular stator core having a circumferential direction, a radial direction, and an axial direction and including a plurality of teeth arranged in the circumferential direction; preparing a plurality of coils respectively wound around the teeth, wherein the coils include a plurality of lead lines drawn in a drawing direction toward outside from one axial end of the stator core; preparing a substrate that is arranged to face the one axial end of the stator core, wherein the substrate includes a plurality of connecting portions extending through the substrate in a thickness direction of the substrate and electrically connected to the lead lines, respectively; positioning the substrate and the lead lines so that distal portions of the lead lines are separated in a separation direction from the corresponding connecting portions, wherein the separation direction is at least one of the radial direction and the circumferential direction; preparing a plurality of positioning jigs, each including a recessed restraining portion that receives one of the lead lines, wherein the restraining portion includes an opening directed in a direction opposite to the separation direction of the corresponding lead line, and the restraining portion, when receiving the lead line, allows movement of the lead line along the drawing direction and restricts movement of the lead line in a direction orthogonal to the separation direction that differs from the drawing direction; inserting the lead lines into the restraining portions by moving the positioning jigs in the direction opposite to the separation direction; aligning the distal portions of the lead lines with the corresponding connecting portions in the radial direction and the circumferential direction using the positioning jigs; inserting the lead lines into the corresponding connecting portions; and electrically connecting the lead lines, which are inserted into the connecting portions, to the connecting portions.
