Abstract: Disclosed are various embodiments for winding heavy gauge coils of electric machines having fractional concentrated windings including one of more of positioning the middle of a predetermined length of heavy gauge wire in contact with an inclined chamfer in a face of a center projection of a fixture tool, simultaneously bending both ends of the heavy gauge wire in a first direction using the center projection to compete the first turn of the coil, simultaneously bending both ends of the heavy gauge wire in a seconding direction using the center projection to complete a second turn of the coil; continuing to simultaneously bend the heavy gauge wire in the first direction and the seconding direction until the required number of even or odd turns are completed, removing one of the adjoining right-angle faces of the fixture tool; and sliding the coiled heavy gauge wire off of the center projection.
