Abstract

PURPOSE: To increase tightening strength between armature-core dovetail grooves and their blocks, by providing a curved portion, which curves for the entire length in the radial direction of a thin plate before lamination and which is flatly rolled after the tightening by an endplate, in the segment thin plate of an armature.
CONSTITUTION: A curved portion 14 is provided in a thin plate 5a of a segment structure for the entire length of the radial direction at the central portion of said thin plate 5a, so that a convex portion is provided on one side of the plate and concave portion is formed on the opposite side. In laminating the plates to form an armature core 5, ends 11a and 11b of the neighbouring segment thin plates 5a which oppose each other on the same plane are contacted, and the gasp are made small as much as possible. If an end plate 7 is tightened under this condition, the curved portions are extended to the circumferential direction, so that the plates are lengthened by ΔL longer than the initial length of L in the circumferential direction at the beginning of the tightening. Since the armature core becomes endless and the diameter of the armature core is increased, the vertical-plane pressure acting on dovetail block contact surfaces 9a and 9b are increased.
