Problems solved by technology

Suspension support utilizes the action of electromagnetic field, and there is electromagnetic damping. Even if the vacuum degree of the gyroscope is increased, the rotational speed of the gyroscope is also limited. At present, the actual measurement level of the rotational speed of the magnetic levitation developed at home and abroad is several thousand revolutions per minute.
At the same time, the gyro does not have a special lateral stabilization device, and the lateral stiffness is low

Abstract

Disclosed is a static electricity supported suspending electromagnetic induction rotary micro gyroscope which comprises a upper stator, a rotor and a lower stator. Wherein the upper and lower stators are individually installed with an adding moment detecting electrode, a public electrode and a rotary driving coin, and the stators are connected together via side electrode and form a circle type cavity in which located a circle type rotor to form a gyroscope system. The invention employs the circle type rotor to perform detection and adding moment control via the side electrode which can add lateral rigidity of the system. A barrier cylinder is used to prevent the rotor contacting the upper and lower stators and to increase stability of the system.
