Abstract

Monitoring the degradation of induction motors is an essential concern for industries, especially when there are high costs related to maintenance and their stops. Nowadays, there are many non-invasive ways to monitor the health status of induction motors, including sensors to measure temperature, magnetic field, vibration, current, and power. However, installing these sensors may not be a simple task since intrusive procedures such as engine disassembling, wire separation, and engine interruption are commonly observed. Thus, we propose MUCLA (Multiphase Clamp and Tracking - patent pending) as a new device and methodology for monitoring motor degradation by analyzing its stator current. MUCLA introduces a non-invasive current sensors array on a proposed clamp in the hardware perspective, while a spectral tracking methodology refers to our novelty in the software viewpoint. For end-users, the main MUCLA contribution relies on the combination of the simplicity of installation and the possibility of using the proposed device even when considering Variable-Frequency Drive powered engines. The results obtained with both simulation and practical tests show encouraging results over different input workloads and emulated degradation. Compared to the current initiatives, we can classify MUCLA as a better solution for industrial plants in terms of installation time, installation complexity, and cost.

提出一种非侵入式监测电机退化的装置和方法
监测感应电机的退化是工业界关注的一个重要问题,尤其是在维护和停机成本高昂的情况下。如今,有许多非侵入性的方法来监测感应电机的健康状况,包括测量温度、磁场、振动、电流和功率的传感器。然而,安装这些传感器可能不是一项简单的任务,因为通常会观察到发动机拆卸、导线分离和发动机中断等侵入性程序。因此,我们提出了MUCLA(多相箝位和跟踪-正在申请专利),作为一种通过分析电机定子电流来监测电机退化的新设备和方法。从硬件角度来看,MUCLA在所提出的夹具上引入了一种非侵入式电流传感器阵列,而从软件角度来看,频谱跟踪方法是指我们的新颖性。对于最终用户来说,MUCLA的主要贡献取决于安装的简单性和使用所提出的设备的可能性的结合,即使在考虑变频驱动动力发动机时也是如此。模拟和实际测试的结果显示,在不同的输入工作负载和模拟退化情况下,结果令人鼓舞。与目前的举措相比,我们可以将MUCLA归类为工业工厂在安装时间、安装复杂性和成本方面更好的解决方案。
