Abstract:
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.
