Method and Apparatus for Manufacturing Coreless Armature

Abstract

A method for manufacturing a coreless armature, which can prevent a short circuit of adjacent terminal layers when resistance-welding the terminal layers, is provided. In a method for manufacturing a coreless armature, terminals 5 of the conducting bands 3 provided to each coil base 1 are stacked to form a terminal layer 23, a welding rod 21 is pressed against a terminal positioned on an outermost periphery so as to interpose the terminal layer 23 between coil jigs 9a and 9b and the welding rod 21, and an electric current is applied thereto, thereby connecting each terminal 5 of the terminal layer 23 by way of resistance welding, in which an insulating material 25 is arranged between terminal layers 23 adjacent in a circumferential direction to resistance-weld the terminal layers 23.
