A system of measurement and analysis is developed to improve the accuracy and efficiency of measurement and to control the dynamic performance of gyro motor.

Motor rotor and spindle, crankshaft, turbine rotor, gyro rotor and escapement rotating parts in the manufacturing process, need to go through in order to smooth the normal operation of balance.

The software phase-locked loop (SPLL) technology in the steady speed control of permanent magnet brushless DC motor (BLDCM) in gyro was discussed.
