A rotating machine performance measurement device having variable load according to the present invention applies load to a rotary shaft of a rotating machine and collects one among the amount of a current applied to the rotating machine, a winding temperature change within the rotating machine, and the rotational torque and rotational speed of the rotating machine when the rotating machine operates. It is desired that an electric load applying device and a hydraulic load applying device are arranged on the rotary shaft. The electric load applying device comprises a rotating rod made of metal materials combined with the rotary shaft; an electromagnet housing passing through one side of the rotating rod; and a coil part arranged inside the electromagnet housing and applying magnetic force to the rotating rod. The rotating machine performance measurement device having variable load according to the present invention is effective in precisely changing load according to the capacity of the rotating machine to be tested by using hydraulic pressure and the magnetic force and more effectively testing the rotating machine by changing the load under test. |
