Abstract
A method includes wrapping a magnet wire around a first side and a second side of each of a plurality of posts of a rotor body to form a plurality of coils on each of the plurality of posts. The method also includes inserting a first wedge liner into a slot landing between adjacent posts of the plurality of posts and inserting a second wedge liner into the slot landing between adjacent posts of the plurality of posts. The method further includes coupling the first wedge liner and the second wedge liner to form a wedge liner opening and inserting a wedge piece into the wedge liner opening.
