Abstract

PURPOSE: To obtain a rotor having their end rings firmly fastened by a method wherein an insulating bushing is fitted on a rotor shaft at sides of a rotor core and an end ring engaged with the insulating bushing is formed around an outer periphery of the insulating bushing.
CONSTITUTION: Retaining portions 21 consisting of male screws are provided on a rotor shaft 2 penetrating through a center of a rotor core 1 at protruding portions from both sides of the rotor core 1. Insulating bushings having specified spaces between copper series rod conductors 3, penetrating through slots 11 of the rotor core 1, and protruded or recessed portions 51 at their outer circumferences are screwed to the retaining portions 21. By pouring fused aluminum through pouring holes 61 of molds 6 provided outside the insulating bushings, the end rings 4 which connect electrically the copper series rod conductors 4 each other are formed, and the end rings 4 are engaged with the protruded or recessed portions 51 on the insulating bushings 5.
