Abstract
A magnet assembly having means for reducing release of magnet material particles from the magnet element includes a body of permanently magnetizable material and a shell at least partially surrounding the body. The shell is disposed and located so as to reduce release of particles shed from the surface portion of the body which is surrounded by the shell, and is preferably attached to the body by an adhesive which bonds the adjacent surfaces of the shell and the body together. A plurality of such magnet assemblies may be fastened to a flux ring in order to provide a rotatable assembly for a dynamoelectric machine in which migration of magnet material particles into the stator-rotor air gap is reduced. In accordance with a preferred embodiment, the magnet assemblies of the present invention are employed in a molded rotor assembly for such a machine.
