A lubricant supported electric motor includes an outer stator and an inner stator, each of the outer stator and the inner stator extending in a radially spaced relationship from each other about an axis. A rotor is rotatably disposed between the inner stator and the outer stator 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 the inner gap and the outer gap for radially supporting the rotor between the inner stator and the outer stator. The lubricant-supported electric motor with a dual-sided radial flux configuration results in improved rotor-stator system stiffness to allow the lubricant-supported electric motor to be used in high impact and high vibration environments while providing high torque in a small and light design package.
一种润滑剂支承的电动机,包括外定子和内定子,每个所述外定子和所述内定子围绕轴线以径向地彼此间隔的关系延伸。转子可旋转地设置在所述内定子和所述外定子之间,以限定在所述转子和所述内定子之间径向地延伸的内间隙以及在所述转子和所述外定子之间径向地延伸的外间隙。润滑剂设置在所述内间隙和所述外间隙中,以用于将所述转子径向地支承在所述内定子和所述外定子之间。具有双侧径向磁通构造的所述润滑剂支承的电动机带来了改进的转子‑定子系统刚度,以允许所述润滑剂支承的电动机用于高冲击和高振动环境,同时在小而轻的设计封装中提供高扭矩。
