摘　　要：本文分析了一种以可调的电阻和直流电压源作为可变的电子负载,在全速范围内实现异步电动机的最大输出转矩的方法,讨沦和计算了电机高速和低速两种情况下的电阻值和补偿电压值,并提出了实验时电阻和电压源选取的原则,通过实验验证了此方案的可行性。The paper introduces a method to acquire the maximal outputting-torque of asynchronous electromotor in the full velocity range. By applying alterable resistance and direct-current electrical source as electronic load, discusses and calculates the value of resistance and electrical source in the case of low and high velocity, and proposes the principle to choice resistance and voltage source in experiment. Finally, we verify the project＇s feasibility by experiment.
