Construction Method and Application Prospect of Electrical Machine Digital Twin

The digital twin (DT) technique, defined as a dynamic mapping for the physical system to virtual replica, has attracted worldwide attention, which can realize the near real-time interaction among human, machine and environment. This paper aims to present an overview on the research status and technologies of the DT technique and propose an overall DT modeling framework for electrical machines. Among them, property modeling for advanced electrical machine design and analysis is one of the most important research topics which will then be fully investigated. Finally, the key problems that need to be broken through are summarized and the application prospect is also discussed. All the above-mentioned works may trigger in-depth thinking and bring research directions for the application of the DT technique in the field of electrical machines adhering to Industry 4.0 ‘informatization, digitalization and interaction’ concepts.
