[0138] Now, refer to Figure 9-15 An armature of a starter according to a second embodiment of the present invention will be described. The armature of the second embodiment differs from the first embodiment in that the contour deformed portion of the upper layer coil extension includes a bent portion formed at an intersection area where the upper layer coil extension and the lower upper layer coil extension intersect each other. Also, the second embodiment is directed to a forming machine for forming a bent portion on an upper layer coil extension drawn from an armature core forming portion of an armature.

[0139] Figure 9 is a perspective view showing an armature forming a part of the starter of the second embodiment. Figure 10-15 is a view showing a forming machine for an armature according to a second embodiment of the present invention.

[0140] With the starter of the present invention, the armature 14B is rotatably supported in the yoke 9 of the starter 1, as fig...

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 acontour 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.

Description

technical field [0001] The present invention relates to an electric rotating machine with an armature coil made of flat wire, and in particular to an electric rotating machine, an armature for an electric rotating machine, a method of manufacturing an electric rotating machine and an armature for an electric rotating machine forming machines. Background technique [0002] In recent years, electric rotating machines (particularly, starters) for mounting on vehicles need to try to downsize the structure by reducing the weight, aiming at reducing the installation space, and improving fuel consumption. For this reason, attempts have been made to provide models of armature coils employing flat wires in order to provide improved lamination ratios, increase output torque, and thereby achieve miniaturization of armatures through light weight. [0003] However, it is known that the flat wire has a narrower creeping discharge path between the upper coil and the lower coil at the inte...
