An electrical machine library; developed within the framework of the European project Actuation 2015; is presented in this paper. The library has been developed adopting a multi-level approach; in order to minimize the models complexity and reduce the computational time. Multi-level approach consists in creating several models of the same electrical machine topology; with different levels of complexity. Indeed; model complexity increases at higher model levels and each model takes into account specific physical effects. In addition to the fundamental behavior; the presented models address physical effects such as losses; magnetic saturation; torque ripple and fault conditions. The interchangeability among model levels is ensured by using common interfaces. An overview of the library structure is given; however; particular attention is paid on the permanent magnet synchronous machine (PMSM) models; since they are becoming increasingly widespread in aerospace applications. The PMSM models description and simulation results are provided; in order to highlight the implemented physical effects and confirm the models effectiveness.
