发明名称 Levitated micromotor
摘要 An electrostatically levitated micromotor is described that includes a generally planar rotor that exhibits an axis of symmetry and includes electrically conductive portions. A balanced stator arrangement is positioned adjacent the rotor and is connected to multi-phase circuitry for enabling the rotation of the rotor about its symmetry. A plurality of levitating electrodes are positioned about the rotor and circuitry is connected thereto for forming resonant circuits that include the conductive portion of the rotor and exhibit a natural resonant frequency. A power source energizes the resonant circuits at a frequency greater than the natural frequency and thereby enables stable levitation of the rotor.
