【Abstract】 At the present time, it usually uses the torque-measuring instrument to measure the output torque in High Efficiency Motors efficiency test. But exchanging the sensors for various measurements should result in increasing the cost. This paper calculated the air - gap torque through testing the input current and voltage, and then accomplishes the efficiency test of High Efficiency Motors. The experiment results show that this method is easy-using and cost less, accords with the High Efficiency Motors testing criterion and it is valuable for application.更多还原
