PURPOSE:To perform an accurate long period running test by setting so that the rotating direction of the first gear becomes reverse to the direction of a rotary torque and the rotating direction of the second gear coincides with the direction of rotary torque. CONSTITUTION:It is set that the rotating direction D of the first gear 14 becomes reverse to the direction or a rotary torque T1 due to a spring 18 and the rotating direction E of the second gear 15 coincides with the direction of a rotary torque T2 due to the spring 18. In this construction, since the gears 14, 15 rotate at the same rotating speed, the elongation of the spring 18 is held constant, and constant returning force of the spring 18 is acted on the first gear 14. Accordingly, since constant rotary torque T1, i.e., a load torque is always applied to a motor 1 to be tested, various running tests of the motor can be accurately performed. |
