Electromechanical drive systems for vehicles and modern variable speed mechanical systems entail complex multiphysics phenomena that span across the mechanical, electromagnetic, electrical, and control domains. Untangling this interplay of dynamical systems and unlocking high-performance solutions requires breakthroughs in the realms of modeling, design, and experimentation. On the analytical front, we are leveraging the universality of energy to formulate equivalent circuit models that reveal the operation of closed-loop drive systems in a lucid and visually intuitive manner. These approaches facilitate new design methodologies which are validated on custom-designed SiC-based drive circuits and high power density axial flux machines.
