A lubricant supported electric motor includes a stator extending along an axis, and a rotor rotatably disposed around the stator in radially surrounding and spaced relationship to define at least one support chamber. A lubricant is disposed in the support chamber for supporting the rotor around the stator. A wheel rim is fixedly attached to the rotor and is disposed in surrounding relationship with the rotor and the stator. Thus, in a first aspect, rotation of the rotor is directly transferred to the wheel rim such that the wheel rim rotates in accordance with the rotation of the rotor. In accordance with another aspect, the rotor is rotatably disposed within the stator, and a planetary gear reduction mechanism is operably interconnected to the rotor, the stator, and the wheel rim and configured to rotate the wheel rim in response to rotation of the rotor within the stator.

An electric motor comprises a stator presenting a first surface. A rotor is rotatable relative to the stator. The rotor presents a rotor raceway disposed in spaced relationship with the first surface of the stator. The first surface of the stator defines a plurality of slots in spaced relationship with one another to define a plurality of spaced teeth between the slots. At least one electrical conductor is disposed in each of the slots and configured to selectively create a moving magnetic field for acting upon the rotor for providing rotational movement of the rotor. A portion of the at least one electrical conductor extends substantially into radial alignment with, or past the first surface of the stator to at least partially define a stator raceway of the stator for engaging the rotor raceway of the rotor during relative radial movement between the rotor and the stator.

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.

A lubricant supported electric motor includes a stator and a rotor and a drive hub. The rotor is moveable relative to the stator and a gap is defined between the rotor and the stator. A lubricant is disposed within the gap to support the rotor relative to the stator and provide a bearing mechanism. The drive hub is coupled to the rotor such that rotation of the rotor causes rotation of the drive hub. The drive hub may be connected to the rotor via a coupler member that is torsionally stiff and axially and radially compliant. The stator may be fixed relative to a connection structure that extends radially within the stator. The connection member may support the drive hub for rotation. Lubricant is supplied via a passageway extending through the connection member into a chamber that includes the gap.

A lubricant supported electric motor including a stator presenting a stator raceway, and a rotor extending along an axis and rotatable relative to the stator. The rotor presents a rotor raceway disposed in spaced relationship with the stator raceway to define a gap there between. A lubricant is disposed in the gap for supporting the rotor relative to the stator. The rotor includes a plurality of rotor poles arranged adjacent the rotor raceway in circumferentially spaced relationship with one another, and the stator includes a plurality of stator poles extending radially towards the rotor in circumferentially spaced relationship with one another along the stator raceway. A plurality of stator coil windings are wrapped around the plurality of stator poles and individually controllable for generating a magnetic force to center the rotor within the stator with carefully-timed adjustments to magnetic fields generated by the stator.

A lubricant supported electric motor includes an outer stator and an inner stator each extending around an axis in radially spaced relationship with one another. A rotor is rotatably disposed between the inner and outer stators to define an inner gap extending radially between the rotor and the inner stator and an outer gap extending radially between the rotor and the outer stator. A lubricant is disposed in both of the inner and outer gaps for supporting the rotor radially between the inner and outer stators. The lubricant supported motor with a two-sided radial flux configuration results in improved rotor-to-stator system stiffness to allow the lubricant supported electric motor to be used in high shock and high vibration environments, while also providing high torque in a small and lightweight design package.

A lubricant supported electric motor includes a stator presenting an outer raceway and a rotor extending along an axis and rotatably disposed within the stator. The rotor presents an inner raceway disposed in spaced relationship with said outer raceway to define at least one hydrostatic support chamber disposed therebetween. A lubricant is disposed in the hydrostatic support chamber for supporting the rotor within the stator. A monitoring port is disposed in fluid communication with the at least one hydrostatic support chamber, and a sensor is coupled with the monitoring port for monitoring an operating characteristic of the lubricant disposed in said at least one hydrostatic support chamber. This monitored operating characteristic is then used to determine a real-time operating condition of the lubricant supported electric motor.
