Abstract
A method and a system for inserting all hairpins of a k-th crown of a stator winding into the same region of space are provided. Progressively inserted hairpins are movable along a path of geometry so that the last hairpin of the crown is always insertable as if the last hairpin were the first hairpin, without hindrance. After inserting the last hairpin the crown centers itself by removing the apparatus that allowed insertion of the hairpins into the same region of space. Inner and/or outer containments allow the hairpins to follow the required profile. Rotation of the hairpins is obtainable by cylindrical or conical pins between the legs of the hairpins. After assembling one crown, outermost crowns are progressively assembled on the system to have the winding without handling the crowns. Once assembled, the innermost crown is vertically lowered along a winding axis to leave sufficient space to assemble an adjacent crown.
