Look-Up Table Based Reduced Order Model of Synchronous Motors for Digital Twin Applications

Electric motors can be represented as non-linear (NL), multiple input multiple output (MIMO), highly interconnected systems. Finite Element (FE) simulations are powerful tools to represent electric motors. However, the process can be time consuming. A Reduced Order Model (ROM) approach emerged as a possible alternative to describe the physical behavior of an electric motor. This paper presents a reduced order model for a Synchronous Reluctance motor, built from a general method for synchronous machines. Currents from simulations and measurement have been compared in time and frequency domains, to explore the possible application of such generated model in Digital Twin applications.
