Digital Twin Service Unit for AC Motor Stator Inter-Turn Short Circuit Fault Detection

Abstract

A modern trend for industry digitalization brings new demands for the development and application of the modeling and simulation approach. It is already not enough to have only a virtual representation of the object and run it independently from the physical object. The Digital Twin (DT) aspect indicates a connection between the physical object and the corresponding virtual twin established by generating real-time data using sensors. The DT represents physical object operation throughout its life cycle, making it an essential tool for improving that object's reliability. In this paper, an application of the DT service unit for AC motor stator inter-turn short circuit fault detection is presented. According to real-time measurements, Linux Robot Operation System (ROS) simulates AC electrical machine-specific behavior in case of unbalanced stator currents and notify about possible fault appearance and propagation. Fault, such as discussed in the paper (AC machine stator inter-turn) is considered one of the most prevalent possible electrical motor failure.
