Structure of rotor for generators and method of manufacturing the same rotor

摘要

The present invention provides a structure of a rotor for a generator in which a rotor capable of being ground very easily with a high accuracy is incorporated. This structure of a rotor comprises a rotor mounted fixedly on a rotary shaft supported rotatably on housings. The rotor comprises cylindrically arranged members in which segmental members of permanent magnets are assembled together cylindrically, and an outer cylinder provided on an outer circumference of the cylindrically arranged members and comprising windings or woven cloths of fibers. A resin material capable of being ground is packed in clearances between the cylindrically arranged members and outer cylinder and in the clearances in the outer cylinder.
