Abstract:
A lubricant supported electric motor includes a stator presenting an stator raceway, and a rotor movable relative to the stator and presenting a rotor raceway disposed in spaced 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 defines at least one hydrostatic support chamber disposed in radially recessed relationship relative to the stator raceway and in fluid communication with the gap. The stator also defines a passageway disposed in fluid communication with the at least one hydrostatic support chamber for providing lubricant to the at least one hydrostatic support chamber and the gap. A flow restriction mechanism is disposed in fluid communication with the passageway for controlling and balancing a supply and pressure of the lubricant in the hydrostatic support chamber.
