Abstract
A fusing apparatus and method is described for forming a fuse joint between an armature wire having electrical insulation thereon and a terminal extending from a commutator bar. The apparatus includes a U-shaped fusing electrode including a central portion having an effective electrical resistance higher than the remaining portions of the electrode. By applying current through the electrode, the central portion is heated to a temperature higher than the remaining portions of the electrode sufficient to remove the electrical insulation from the armature wire and to fuse the armature wire to the terminal.
