High Speed Permanent Magnet Generator for Aerospace Applications
AIR7152
This document aims to capture technology particularities and intrinsic failure modes specific to permanent magnet (PM) machines, in relation to traditional wound field machines, both from the design performances stand points. It will identify specific failure modes and propose ways of mitigations to consider for their safe design and usages.
Rationale: Hybrid-electric platforms are currently under development by multiple aircraft manufacturers. In addition, more-electric engine platforms for future aircraft programs are demanding more electrical power. This has led to the development of permanent-magnet (PM) electrical generators for Aerospace applications primary driven by their potential higher power to weight ratio compares to traditional wound field synchronous generators.
The intent of this Aerospace Information Report (AIR) is to gather information and define characteristics in relation to the usage of PM generators for Aerospace applications.
