Hardware-Based Formulation and Validation of Synchronous Machine Models for Aerospace Electric Power Systems

Robust and efficient electric power systems (EPS) are fundamental for the advancement of airborne electric and hybrid electrical propulsion. In particular, electric machines fulfill a central role in the electromechanical architecture that demands a specific power density, efficiency, and performance that must be maintained throughout their lifetime. In this paper, a population of fielded aerospace electric machines at various stages in their life cycles was experimentally tested and parameterized. These results are leveraged to tune and develop representative models to be used in simulation and emulated case studies. Then, the behavior of the model is compared to the responses of the population of tested machines.
