Modern aircrafts rely heavily on electrical systems. This huge electrical dependency is because from some years ago, aerospace systems are experiencing a conversion from using hydraulic, pneumatic and mechanical power systems towards optimized electrical systems.

For future aircrafts, the trend towards electrification is expected to persist, and electrical generators gain importance as primary source of the systems’ energy. Electric equipment and systems expand inside the aircraft, and hydraulic actuators will be backed up or replaced by electromechanical actuators. For systems design and systems integration testing, electric machines need to be simulated with different levels of abstraction, and resulting models must allow estimation and edition of constructive machine parameters. These parameters make that simulation models for electrical machines appear as one of the most interesting for current simulation platforms.

While the detailed machine design often makes use of FEM computations, system interaction is tested by simulators for physical modelling, which implies to use parametric models in machine models. Besides, FEM and subsequent interfacing and auxiliary tools are very time consuming. 
Modelica , an object-oriented multi-domain language for modeling of heterogeneous physical systems, was designed to avoid the excess of time consuming since it employs an equation based modeling, which results in a faster modeling process and a significantly increased reusability of the models.

Knowing that open libraries of detailed rotating electric machinery including common machines as permanent magnet and externally excited synchronous machine and induction machine already exist with special emphasis on the machines’ loss modeling.; we have to take into account that However, they consider fully symmetrical machines and distortions of magnetic flux are not included yet.
