Electro-Magnetic Design and Analysis for a High Performance, Aerospace Electrical Machine

The ever-increasing need for more sustainable modes of transport is escalating the demand for higher performance electrical machines. For these machines to be of practical use in real-world applications, their respective power and torque density must increase. Permanent Magnet Synchronous Motors (PMSM) are renowned for their capacity to be both power and torque dense, however the industrial requirements are still very challenging to achieve. In fact, novel design processes and methodologies were required for the electrical machine to achieve the performance standards required for aerospace applications. Thus, this paper’s objective is to design, simulate and model a 30kW motor for a two-seater aircraft. A multi-disciplinary approach consisting of both electro-magnetic and thermal models is proposed and validated. Using Finite Element Methods, geometric models of the stator, rotor, and magnets have been constructed and optimized.
