Multiphysics Thermal Digital Twin of a High Power Density Motor for Automotive Applications

A multiphysic Digital-Twin of a high power density electric motor for automotive applications is presented in this work, with the objective of real-time monitoring of critical temperatures of interest. The model includes electromagnetic, fluid-dynamic, and thermal effects. The models developed are described and, aiming to achieve reduced computational cost, the Model Order Reduction strategy is presented. This allows compatibility with an on-chip implementation, thus unlocking advanced and informed control strategies. Experimental validations demonstrate the accuracy and the feasibility of the multiphysics Digital-Twin.
