A Research on the Torque Converter Performance Test-Bed Control System

According to the characteristics of test bed, using a motor driven program based on inverter with a speed sensor, and an eddy current dynamometer constant torsional loading scheme, it implements the stability of constant speed drive and torsional load for the torque converter test-bed, providing a good test environment for the performance test. This method is economical and practical, energy saving and environmental protective. The constant voltage-frequency ratio of frequency control method is applied in motor speed control, and a way of changing the excitation voltage to change the output torque of the eddy current dynamometer is used. The results show that the system achieve good control results.
