Abstract:
     This invention relates to an asynchronous sensing micro-mechanical gyroscope for the active suspended permanent magnetic ring rotor including: an upper stator, a ring rotor and a lower stator, in which, lateral capacitor boards are set on the lower stator connected with the upper stator by the boards to form a circular cavity, the ring rotor is set in the cavity and has large moment of inertia under the same rotating speed and is stabilized by DC, so it is controlled simply, the asynchronous sensing motor can realize rotating at high speed of the ring rotors and design of the capacitor is convenient for picking up peg-top signals.
