Impact of Machine Parameters on The Design of High Specific Power Permanent Magnet Machines for Aerospace Applications

Abstract

Aerospace applications demand high Specific Power (SP) electrical machines to enable hybrid/electric propulsion. The targets for SP are 2-3X the state-of-the art. Therefore, the adoption of novel technologies including advanced and lightweight materials, additively manufactured coils, as well as innovative and tight integration of Thermal Management System (TMS) to the machine and its Power Electronic Unit (PEU) are effective design methods to boost the electric drivetrain SP. This paper aims to use the foregoing techniques and perform a study to examine the impact of key design parameters on the machine SP.
