The Hardware Design of Test-Bench for Motor Energy Efficiency Based on Torque-Meter Method

According to the demand of accuracy detection of the motor energy efficiency, the hardware of testing bench for motor based on torque-meter method was designed. A design emphasis on loading equipment and torque sensor was introduced in accordance with the requirements of torque meter method, realized the rapid response of the load, the low speed stability of the work and electrical energy reutilization. The proposed error modification method ensured the accuracy and reliability of test results.
