Abstract:
    An electric rotary machine, an armature for use in the electric machine, a method of forming an electric rotary machine and a forming machine for an armature of an electric rotary machine are disclosed wherein insulator-coated coils are wound in slots of an armature core from which lower and upper layer coil extensions extend and are connected to a commutator. The upper layer coil extension has a contour deformation part at an intersecting region where the lower and upper layer coil extensions intersect with each other to have an insulating distance between the lower and upper layer coil extensions. The forming machine includes a work holder holding the armature, and a forming jig forming a curvature portion on the upper layer coil extension.
