CORELESS ARMATURE
Document Type and Number:
Japanese Patent JPS61128742
Kind Code:
A
Abstract:
PURPOSE:To enable wires to be jointed without forming a bridge with auxiliary substance or the like, by a method wherein jumper wires connecting a commutator to an armature are jointed to wires getting out of phase together by one piece. CONSTITUTION:The both end sections of the first cylinder 10 and the second cylinder 20 organized to be arranged side by side are directed to the axis, and at the intermediate sections, one of the cylinders is twisted at the angle of 180 deg. and the other cylinder is twisted in the opposite direction at the angle of 180 deg. + or - one piece wire thickness. At the one end of the both cylinders, the wires of the both cylinders are heaped up together block by block in the radial direction of the cylinders, and at the other end of the cylinders, the wires are arranged getting out of phase together by one piece. The boundary faces between wires in phase are jointed together by laser. Wires 11, 21 getting out of phase are protruded from other wire end faces, and the protruded sections are placed between jumper wires 41, 42, and pins 60 are pressed in confronted insulation substance 52. In this manner, the wires 11, 21 getting out of phase are exactly jointed together.
