The invention employs a first sensing means for generating a first sinusoidal position signal and a second sensing means for generating a second sinusoidal position signal. Also, the invention employs the generation of a direct current error signal which in conjunction with the first sinusoidal position signal produces a first motor control signal. Similarly, the direct current error signal in conjunction with the second sinusoidal position signal produces a second motor control signal. The resulting motor control signals drive two pair of motor coils of a gyro motor with speed and rotational direction control for the gyro motor being provided by the direct current error signal.
