PROBLEM TO BE SOLVED: To provide a motor evaluation device for improving the upper limits of both of measurable torque and rotation speed and evaluating both a testing motor generating a large torque power and a testing motor rotatable in high speed. SOLUTION: To a loading motor 6 for providing a testing motor with a load, a first rotor 20 and a second rotor 22 are provided and these are made capable of jointing and separating with a connection mechanism 24. In jointing state, the power shaft 12 where the first rotor 20 is attached and a shaft 34 where the second rotor 22 is attached are connected in series and maximum power torque increases with the two rotors. On the other hand, by separating them, parts relating to the second rotor 22 is removed from the inertia moment of the rotor of the loading motor 6 connected with the testing motor. By the reduction of the inertia moment, a twist resonance point becomes high and evaluation in high speed region becomes possible. COPYRIGHT: (C)2004,JPO
