摘要 从信号处理的观点出发 ,结合阻抗理论和谐波分析 ,提出了感应电机系统无传感器监测的谐波阻抗和谐波导纳法 ,给出了获取和计算谐波阻抗和谐波导纳的方法。在鼠笼式三相感应电机上用提出的方法进行了转子失衡的实验研究。实验结果证实了方法的可行性 。 Based on the impedance theory and harmonic analysis, this paper presents a harmonic impedance/admittance signal processing method for sensorless condition monitoring of induction motor systems. An algorithm to compute the harmonic impedance and admittance is developed by means of digital signal processing. A rotor unbalance experiment is carried out on a three phase squirrel cage induction motor. The result shows that the proposed method is effective and has advantage over the traditional method in ability against external disturbance.
