Abstract: Large-torque torque motors are key basic components of the high-grade numerically-controlled machine tools. The testing technology for the performance of the torque motor servo system was researched in the paper. A servo control system was introduced fistly, and then put forward the general scheme of the system for testing. Finally the filter of the servo system was tested and the test results were analysised.
Key Words: Torque motor; Servo system; Performance testing
