ROTATOR FOR DYNAMOELECTRIC MACHINE AND ITS MANUFACTURING METHOD

摘要

An object of the present invention is to provide a dynamoelectric machine that can be manufactured merely by adding simple work without the necessity of increasing the number of parts and that is characteristic of a minimized electromagnetic sound. Included are a pair of field cores (12) having a plurality of claw-like magnetic poles (12a) on the outer circumference thereof and being arranged so that the claw-like magnetic poles (12a) can alternately mesh with one another, a coil frame (14) caught in the pair of field cores (12), a field coil (13) wound about the coil frame (14), and varnish layers (18) interposed between the field cores (12) and coil frame.
