Digital Twin of an Electrical Motor Based on Empirical Performance Model

The concept of Digital Twin is creating and maintaining a digital representation of the real physical entity and supporting its performance utilizing simulation and optimization tools, which are fed with real data. Development and implementation of Digital Twin technology is a hot topic in many industry-oriented research projects. However, more detailed studies are needed on design methods for Digital Twins, which allows full synchronization and connectivity between virtual and real environments. This paper presents a development case study of Digital Twin for an electric motor based on an empirical performance model. The paper discusses the way how the data required for the Digital Twin were obtained and present a detailed structural description of the virtual entity. Unity3D is used for physics simulations and visualization of the Digital Twin, because of simple accessible and meticulously detailed documentation highly useful for rapid prototyping in early stages.
