ROTOR, DYNAMO-ELECTRIC MACHINE HAVING THE ROTOR AND ROTOR MANUFACTURING METHOD

摘要

A cover is configured into a tubular form and is fitted to a radially outer surface of each of projections of a rotor core and a radially outer surface of each of permanent magnets. A circumferential center portion of the radially outer surface of each projection contacts a radially inner surface of the cover. Circumferential end portions of the radially outer surface of each projection are radially inwardly spaced from the radially inner surface of the cover.
