I\Main functions
The loading system of this machine, controlled by computer, rotates load through alternating servo motor and cycloidal gear reducer. Torque and twist angle detection uses the high-precision torque sensor and a photoelectric encoder; Computer displays dynamically the curve of test torsion angle and torque, rate of loading, peak of power and so on.
