A permanent magnet rotor for use in a dynamo electric machine comprising: a rotor hub defining an intended axis of rotation; a plurality of circumferentially spaced magnets on said hub; filler material disposed between adjacent ones of said magnets; axially spaced opposed side plates on said hub sandwiching said magnets and said filler material, each said side plate having a stepped periphery including an axially inner, generally cylindrical surface of substantially the same diameter as the hub with the magnets and filler material in place and an axially outer, generally cylindrical surface of a greater diameter than said same diameter to define a radially outward opening annular recess; and a generally cylindrical body of cured fibrous material in said recess and having an outer diameter equal to said greater diameter.
