Phase-locked Constant-speed System of a High-accuracy Brushless DC Gyro Motor

A phase-locked steady-speed system of two-phase sensorless brushless DC gyro motor is designed. It can combine with single-chip microcomputer and programmable logic controller to realize the processing of digital signals using simple electronics. In phase-locked state, the phase pulse of motor tracks the basis pulse and the motor runs at steady-speed. Experiment shows that the system is practical, reliable and high accuracy.
