Abstract
Methods and apparatus for enhancing the robustness and stability of an electric machine having a rotor, stator and housing. The rotor includes a radially mounted array of permanent magnets and the stator includes a plurality of electromagnets radially positioned around the rotor. The rotor is stabilized by providing a first thermally conductive dielectric encapsulant in contact with adjacent permanent magnets. The stator is stabilized by providing a second thermally conductive dielectric encapsulant in contact with adjacent electromagnets.
