換運転装置。[Claims for Utility Model Registration] A main thyristor is phase-controlled by the summed output signal of the output signal of the speed control amplifier and the output signal of the torque control amplifier, and the DC dynamometer and the electric dynamometer are controlled separately by the control output signal. In a dynamometer operating device in tandem operation to be controlled, the speed control amplifier of the DC dynamometer is configured so that the DC dynamometer and the editorial dynamometer share the same speed control gain, and the speed control gain is switchable. and a response switching signal generating circuit which calculates the outputs of both the load cell and the pulse pickup and switches the gain of the speed control amplifier when the rated torque and rated capacity are greater than, equal to, or less than the rated torque and the rated capacity. Automatic switching operation device for dynamometer.
