摘　　要：对异步电动机起动过程中阻抗变化曲线进行了深入分析 ,根据转差率与机端测量阻抗的变化特性 ,给出了起动过程中堵转的判定方法。利用 MATLAB软件中的动态仿真工具 SIMULINK建立了异步电动机起动过程的仿真模型 ,仿真结果验证了判据的正确性。This paper deeply analyzes the impedance curve of the asynchronous motor starting process,and according to the characteristic that the measurement impedance of a asynchronous motor changes with the slip ratio,presents a criterion to judge locked rotor during the starting process of the asynchronous motor.In this paper SIMULINK,a dynamic simulation tool in MATLAB software, is used to establish the simulation model of the asynchronous motor starting process,and simulation results verify the correctness of the judgement criterion.
