Electrial and Magnetic Materials in Hybrid Aerospace
AIR7219
An overview of the degradation mechanisms in permanent and soft magnetic materials and the implications for hybrid & more-electric aerospace applications
Rationale: There is an increased use of electrical machines (motors, generators and actuators) in aerospace applications, these machines are subject to temperature, stress, pressure, electrical and magnetic cycling all of which alter their performance over time. This SAE Aerospace Information Report is intended to provide reference and background information pertaining to the degradation mechanism in permanent and soft magnetic materials.
