Abstract
Stator coils are retained by an inserting blade and a setting blade. The setting blade is rotated in this state. Then, after rotation, the stator coils are set on the inserting blade. At this time, the stator coils are arranged in the inserting blade in a state where the stator coils overlap one another to form a spiral shape. Thus, the stator coils are arranged uniformly.

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 method comprising:
- retaining a first section and a second section of each stator coil by a first member such that the stator coils are arranged about the axis at equal intervals to extend in a radial pattern;
- moving the second section of each stator coil from the first member to the second member so as to retain the stator coils by the first member and the second member;
- rotating the first member or the second member about the axis to generate a phase difference between the first section and the second section of each stator coil;
- and
- setting the stator coils on the inserting blade while maintaining the phase difference between the first section and the second section.
A method for manufacturing a rotating electrical machine, which includes a stator core on which a plurality of stator coils are mounted in a state where the stator coils overlap one another to form a spiral shape as a whole, the method comprising:
- retaining a first section and a second section of each stator coil by a first member such that the stator coils are arranged about the axis at equal intervals to extend in a radial pattern;
- moving the second section of each stator coil from the first member to the second member so as to retain the stator coils by the first member and the second member;
- rotating the first member or the second member about the axis to generate a phase difference between the first section and the second section of each stator coil;
- setting the stator coils on the inserting blade while maintaining the phase difference between the first section and the second section;
- and
- inserting the stator coils set on the inserting blade in slots formed in the stator.
