    Abstract: In free-rotor flexure suspended gyroscopes it is common to mount the inertia wheel-gimbal at one end of the drive shaft and to mount the motor drive assembly at the other end of the shaft. This arrangement usually produces an offset between the mass center of the inertia wheel-gimbal assembly and the rotation axis of the shaft. The offset, in turn, creates a dynamic torque unbalance which causes a ''''wobbling'''' or vibration about the gyroscope mounting plane. In order to cancel this dynamic unbalance torque, a pair of dissimilar masses are positioned within the gyro''s motor hub assembly. The masses, which are diametrically opposed within the plane of unbalance, are also axially displaced relative to one another. The resulting arrangement balances the forces and torques acting on the rotating portion of the gyroscope thereby cancelling the vibrations in the mounting plane.
