Acceleration of contactless gyroscope in resistant medium
Abstract
An analysis is made of the motion of a symmetric rigid body about its center of mass in a resistant medium, with an active torque sustaining a constant angular speed of rotation. The moment of resistance is assumed to be a linear function of the angular speed of the body, and the active moment is generated due to the effect of a rotating magnetic field applied to a conductor. The rotating magnetic field is produced by the drive system of the gyroscope rotor, as in the case of the stator of an asynchronous motor. Stability conditions for the stationary rotation of the gyroscope are obtained both in the nonresonance case and in the resonance case, where the nutation frequency of the rotor is equal to the angular speed of the field.
