Description

この発明に係る積層固定子の製造方法は、本発明に係る積層固定子鉄心の対向する２つの積層ヨーク部間を広げることにより、同時に各積層ティース部の対となる積層ティース先端突出部の間隔を縮めた状態で、予め巻回したコイルを各積層ティース部の外周面に装着し、その後、対向する２つの積層ヨーク部間を縮めることにより積層ティース先端突出部の間隔を広げて、コイルを積層ティース先端突出部と積層ヨーク部が形成するスロット内に密着させるものである。 The manufacturing method of the laminated stator according to the present invention is such that the space between the two laminated yoke portions facing each other of the laminated stator core according to the present invention is increased so that the intervals between the laminated tooth tip protrusions simultaneously serving as a pair of laminated tooth portions are as follows. in a compressed state, and fitted with a coil wound in advance around the outer peripheral surface of each of the laminated teeth, then, by increasing spacing laminated tooth end projecting portion by shortening between two stacked yoke portions facing the coil This is closely attached in a slot formed by the protruding portion of the stacked teeth and the stacked yoke portion.
