A gyroscope comprises a rotor driven by a motor shaft through the intermediary of an intermediate ring connected to the motor and to the rotor by torsion bars at 90 DEG with respect to each other and precession motors for applying to the rotor, precession torques in planes containing the axis of rotation of the drive shaft. Precession motors are fixed electromagnets exerting a force of attraction on the rotor. A system for supplying current to the electromagnets is provided, reacting to a control by an electrical control signal, this system having a response such that the attraction torque exerted by a pair of diametrically opposed electromagnets is a linear function of a parameter of the signal for controlling the current applied to the electromagnets. The gyroscope may have an elastic suspension and be intended to rotate at high speed. |
