Abstract

Induction motor drivetrains are commonly utilized as the power unit of various industrial equipment. By taking the induction motor itself as a built-in sensor and analyzing the stator current, noncontact health condition monitoring of the rotary machinery in the drivetrain can be realized. Reported works on this topic have qualitatively validated the effectiveness of such technique, yet its applicable boundary has not been quantitatively elaborated. This article analytically models the strength of the rotary machinery fault signatures in stator current based on electromechanical coupling. The correctness of the proposed quantitative model and its nonlinear characteristics are numerically validated via finite-element simulations. Experiments under impulsive load torque oscillation and gear wear degradation further quantitatively evaluate the applicable boundary of the stator-current-based fault detection in real-world applications. The proposed analytical model and the revealed quantitative characteristics can help optimize the utilization of induction motor stator current analysis in the predictive maintenance of induction motor drivetrain.

感应电机定子电流中旋转机械故障特征的定量特征：建模与评估

感应电机传动系统通常用作各种工业设备的动力单元。将感应电机本身作为内置传感器，通过分析定子电流，实现对传动系统中旋转机械的非接触式健康状态监测。关于这一主题的报告工作定性地验证了这种技术的有效性，但其适用范围尚未定量地阐述。本文建立了基于机电耦合的旋转机械定子电流故障特征强度的解析模型。通过有限元仿真验证了该定量模型的正确性及其非线性特性。脉冲负载转矩振荡和齿轮磨损退化实验进一步定量评价了基于定子电流的故障检测在实际应用中的适用范围。所建立的分析模型及其揭示的定量特征有助于优化异步电机定子电流分析在异步电机传动系统预测维护中的应用。

期刊介绍： The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
