Claim 0:
1. A lubricant supported electric motor comprising:
a stator presenting a stator raceway;
a rotor movable relative to said stator about an axis and presenting a rotor raceway disposed in radially spaced and opposing relationship with said stator raceway to define a gap therebetween;
said stator raceway including a bearing structure comprised of a plurality of hydrodynamic surfaces aligned in parallel relationship along said stator raceway and a plurality of hydrostatic pockets disposed in radially recessed relationship relative to said plurality of hydrodynamic surfaces;
a plurality of lubricant supply tubes disposed in fluid communication with said plurality of hydrostatic pockets to deliver a lubricant to said plurality of hydrodynamic pockets and then consecutively to said plurality of hydrodynamic surfaces and said gap for establishing support of said rotor relative to said stator; and
said stator including a drain gutter arranged central to said stator raceway and disposed in radially recessed relationship relative to said plurality of hydrodynamic surfaces and extending circumferentially along said stator raceway in axially spaced relationship with said plurality of hydrostatic pockets.
