ABSTRACT:
A rotor assembly for a rotating machine includes a substantially cylindrical main rotor body having an outer surface. A plurality of longitudinal ribs project from the outer surface of the main rotor body. A plurality of primary recesses are defined by adjacent ribs and a secondary recess is defined in the outer surface within at least one primary recess. A magnet is positioned within at least one primary recess, and a layer of adhesive between the magnet and the outer surface of the main rotor body fills the secondary recess. Magnet retaining elements in the form of either an encapsulation layer, star-shaped retainer or elongated retaining members may also be used. The magnet retaining elements may be used alone or in combination with the adhesive layer between the magnets and the main rotor body.
