ABSTRACT:
A permanent magnet type rotor comprises an inner member2having an outer ring portion21; an approximately annular outer member1having soft magnetism and an inner circumference contacting with an outer circumference of the outer ring portion; and plural permanent magnets3disposed at equal intervals on the outer circumference of the outer member toward the circumferential direction. At least one of the inner member2and the outer member1is made from a sintered material, and the inner member2and the outer member1are mutually sintered and bonded. Thickness and weight of a dynamotor itself can be reduced and high output and high efficiency can be achieved.
