加载效率是衡量舵机性能好坏的重要指标,因此需要进行舵机加载效率的测量。以磁粉制动器为负载,利用转矩转速传感器获取电动舵机的输出功率,电压探头和电流探头获取电动舵机的输入功率,由四通道示波器进行输入/输出同步测量,即可根据效率计算的基本原理计算得到舵机加载效率。实际测试结果表明,该系统能够准确测量舵机在不同加载转矩下的效率,具有较高的测量精度和测量重复性,能够满足舵机研制和测试过程中对电动舵机加载效率测试的需求。
Loading efficiency is a measure of the performance of the servo is an important indicator of quality, so the need for servo loading efficiency measurement. Take the magnetic brake as the load, use the torque sensor to obtain the output power of the electric servo. The voltage probe and the current probe obtain the input power of the electric servo. The input / output of the four-channel oscilloscope can be measured synchronously. The principle calculates the servo loading efficiency. The actual test results show that the system can accurately measure the servo steering efficiency under different loading torque, with high measurement accuracy and repeatability of measurement, to meet the servo steering wheel manufacturing and testing process requirements for the loading efficiency test of electric servo .
