Method of manufacturing coil assembly

A method of manufacturing a coil assembly of a rotary electric machine, comprising:

• a preparing step for preparing first and second woven coil wire segments;
• a locating step for locating the first and second woven coil wire segments in opposition to each other on the axis direction such that a first turn portion of the first woven coil wire segment and a first turn portion of the second woven coil wire segment intersect with each other;
• a first engaging step for conducting an engaging movement, composed of a forward transferring movement to transfer the second woven coil wire segment forward to the first woven coil wire segment, a rotating movement to rotate the second woven coil wire segment about the axis direction, and a translating movement to translate the second woven coil wire segment, for causing the first turn portion of either one of the first and second woven coil wire segments to engage a second turn portion of the other one of the first and second woven coil wire segments;
• and
• a second engaging step for conducting the engaging movement to allow the first turn portion of the either one of the first and second woven coil wire segments to engage a third turn portion of the other one of the first and second woven coil wire segments;
• whereby the first and second woven coil wire segments are woven to form the coil assembly.
