Abstract

The selection of an electric machine type and design is highly dependent on its application. Unlike automotive applications where the cost, efficiency, and manufacturing complexity are major concerns, aerospace applications demand high power density combined with high levels of safety and reliability. This study is focused on identifying the requirements and challenges associated with designing high-performance machines for aircraft applications with increasing levels of electrification. Different types of synchronous machines are analyzed and their performance metrics are compared against the requirements.
