又は直流電流を制御する。The control system of the drive-side electric motor 2 compares the set value of the speed setting device 4 and the detected value of the speed detector 5, outputs it to the speed control amplifier 6 as a current command, and combines this current command with the current detected value of the motor 2. By comparison, a current control output is obtained to the current control amplifier 7, and the alternating current or direct current supplied from the power converter 8 to the electric motor 2 is controlled.

かがハンプ現象発生を判定する。Here, a changeover switch 14 for switching from the output of the speed control amplifier 11 to the output of the speed control amplifier 6 is provided at the current command input of the current control amplifier 12. This changeover switch 14 is switched to the speed control amplifier 6 side when the hump phenomenon detection relay 15 detects the hump phenomenon of the viscous joint 1. For example, the detection of this hump phenomenon is carried out by relay 15.
monitors the temperature of the viscous joint 1, and determines that a hang phenomenon has occurred (including immediately before the hump phenomenon occurs) when this temperature exceeds a set level. Further, based on the relationship between the temperature and the rotational speed difference ΔN shown in FIG. 3, occurrence of the hump phenomenon is determined based on whether the temperature exceeds the temperature determined for each speed difference ΔN.

ことができる。With the above configuration, when a hump phenomenon occurs in the viscous joint 1 during a test with a rotational speed difference ΔN, the changeover switch 14 is switched to the speed control amplifier 6 side by the relay 15, and the input shaft of the viscous joint 1 and Even when the output shaft is locked and the rotation speed is the same (△N-〇), motors 2 and 3 are given the same current command or proportional current command and are controlled to the same speed, causing overcurrent in both types of motors 2 and 3. The test can be continued without overvoltage generation. When the locked state is released due to a decrease in the temperature of the viscous joint 1, the switch 14 is reset to return the two types of movators 2.3 to the original test using the speed difference ΔN.
