Electrical machines for aerospace applications are characterized by their high-power-density and fault tolerance capability.

Abstract
Electrical machines for aerospace applications are characterized by their high-power-density and fault tolerance capability. Therefore, PM machines with high current densities are the widely used option for such application. This paper presents a study of the influence of the manufacturing and drive effects on a PM machine designed for high-speed, high- power-density aerospace flooded pump application. Three models have been created, the original model (ORI), a model with the properties of the characterized stator core material (CHM), and the final model with the characterized material and the high-speed measured current waveform, i.e. drive effect, (CHMDE). A global genetic algorithm multi-physics optimization consisting of electromagnetic, mechanical and thermal models has been used to optimize machines. Finally, a comparison between the three optimized models and the original machine is given.File | Dimensione del file | Formato | |
