Abstract:
A lubricant supported electric motor includes a stator presenting a stator raceway, and a rotor movable relative to the stator about an axis. The rotor presents a rotor raceway disposed in radially spaced and opposing relationship with the stator raceway to define a gap therebetween. A lubricant is disposed in the gap for supporting the rotor relative to the stator. The stator raceway includes a bearing structure comprised of a plurality of hydrodynamic surfaces aligned in parallel relationship along the stator raceway and a plurality of hydrostatic pockets disposed in radially recessed relationship relative to the hydrodynamic surfaces.
