A permanent magnet type rotor comprises an inner member 2 having an outer
ring portion 21; an approximately annular outer member 1 having soft
magnetism and an inner circumference contacting with an outer
circumference of the outer ring portion; and plural permanent magnets 3
disposed at equal intervals on the outer circumference of the outer
member toward the circumferential direction. At least one of the inner
member 2 and the outer member 1 is made from a sintered material, and the
inner member 2 and the outer member 1 are mutually sintered and bonded.
Thickness and weight of a dynamotor itself can be reduced and high output
and high efficiency can be achieved.
