FIELD: instrumentation.SUBSTANCE: gyro comprises a spherical rotor in the housing with three pairs of orthogonally arranged support elements, the electronic control unit of the suspension of the rotor and the unit of determining position of the vector of the angular momentum of the rotor. Each supporting element is made in the form of a two-phase rotation stator with the main and the control windings on the tooth magnetic circuit. The magnetic circuits are isolated from the housing and applied as a measuring and (or) supporting capacitor electrodes, and the magnetic circuits with the main windings are used as the supporting and (or) measuring electromagnets. Dynamically unbalanced rotor is made with a prolate ellipsoid of inertia. The outlets of the unit of determining the position of the vector of the angular momentum of the rotor (according to the beat signals of the unbalanced rotor) are connected through intensive-converting devices with the control windings of the stators of rotation, which enables to give the proposed gyro the properties of free gyro with limited run-time of the rotor, caused, for example, by the rotor friction on the gas residues in the evacuated casing. The proposed universal gyro can also be used in the mode of the angular velocity sensor (AVS), and as three-axial accelerometer.EFFECT: gyro is characterised with the simple design, it is intended to implement small-sized, with the rotor diameter of less than 10 mm, for use for example in underground navigation, the small size of the rotor causes a high overload capability of the gyro, necessary when working in bottomhole inclinometer.6 cl, 9 dwg |
