Summary:The research of the influence of gyro motor speed stability on the north-seeking result is studied in order to improve the gyro north-finding precision. The paper introduces a two-phase brushless DC gyro motor control system based on TMS320LF2407A. First it expounds the two-phase brushless DC motor's working principle. Then through the design of the hardware and software system, the two-phase brushless DC gyro motor control is realized. The experimental results show that: the system can drive the brushless DC gyro motor starting, braking and smoothly running. The precision of the steady speed is less than 10 -4 and the characteristics of the system satisfy the gyroscope demand.
