Method of assembling a stator for an electric motor |
摘要 |
In assembling a stator being divided into a pole portion and a yoke portion and provided with a winding on the insulated pole portion, the yoke portion is forcibly enlarged outwardly, whereafter the tip ends of the projections of the pole portion are fitted in the recesses of the yoke portion. The two opposing surfaces of each recess are made parallel to each other and the bottom surface of the recess is made parallel to the outer peripheral surface of the yoke portion. The thickness of a portion existing between the bottom surface and the outer peripheral surface is not exceeding 3% of the diameter of the yoke portion and is not less than the thickness of an iron plate of the laminated iron core, whereby the press-fitting load applied when the pole portion is fitted into the yoke portion enlarged is reduced. Thus, even a large-sized stator iron core can readily be assembled and an electric motor of improved properties and enhanced output obtained.
