A rotational electric machine stator has a rectangular wire that includes a lead wire covered with an insulation coating, terminals that is connected to the rectangular wire by thermal fusing, and convex portions provided on the terminals so as to protrude from the terminals toward the rectangular wire, wherein the insulation coating is removed. The method and system further includes a computer system that is configured to receive the collected data points from the catheter and to compute the alpha shape of collected data points to thereby generate a surface model of the anatomic structure. The conductor tracks are electrically coupled to the chip via wire jumpers, which extend through a bond channel which is filled with a mold compound.
