Patent ID: 7882619

Claim:
A method for setting a plurality of stator coils on an inserting blade before mounting the stator coils on a stator core using the inserting blade such that the stator coils overlap one another to form a spiral shape, the stator coils including a starting stator coil and an ending stator coil, the method comprising: setting the stator coils on a coil holder in a predetermined coil setting direction, from the starting stator coil so as to overlap one another, the coil holder being the inserting blade or a setting jig from which stator coils are shifted to the inserting blade, the coil holder including a plurality of coil holding portions to define a plurality of slits arranged at equal pitches in an annular shape, each of the stator coils having a first section and a second section, there being a phase difference between the position of the first section and the second section of the same stator coil on the coil holder, the stator coils being inclined with respect to the axial direction of the coil holder such that the first section of one stator coil overlaps the second section of the next stator coil in the axial direction, and the second section of the next stator coil is inserted inward of the first section of the one stator coil in the axial direction; before setting the ending stator coil on the coil holder, lifting the first section of the starting stator coil from the coil holder to avoid interference between the first section of the starting stator coil and the second section of the ending stator coil, with the second section of the starting stator coil remaining inserted in the coil holder; setting the ending stator coil on the coil holder; and after setting the ending stator coil on the coil holder, setting the first section of the starting stator coil on the coil holder.
