Abstract
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.
