ABSTRACT:
A permanent magnet rotor includes a rotor core having an axis of rotation and longitudinally extending radially projecting ribs. A plurality of arcuate magnetic elements are retained against an outer surface of the rotor by a cylindrical shell such that each magnet is disposed between a pair of the ribs. A hardenable adhesive is interposed between the outer surface of the core and the magnets and cooperates with the ribs and magnets to prevent rotational slippage of the magnets relative to the core during rotation of the rotor. Various embodiments utilize different techniques for retaining the components in assembled relation.
