Basic Gyroscope Spin Motor Excitation Requirements For USD Gyroscopes
This applications note discusses basic gyroscope spin motor excitation requirements for many models of USD Rate Integrating Gyroscopes (RIG) and Rate Gyroscopes. Most USD gyroscopes utilize 2 phase synchronous (hysteresis) motors to drive the gyroscope inertia wheel. The aim of this note is to introduce system designers and engineers to the basics of 2 phase synchronous induction hysteresis motors used in gyroscopes along with the motor drive excitation requirements. In addition, basic circuitry for the excitation of the 2 phase synchronous spin motors will also be discussed. The reader can then expand on the information presented here as applicable to their specific application.
