Defining the Magnetization State of LCF Magnets: From Material Properties to Motor-Level Metrics
Taha El Hajji, Aleksandr Nadkin, Stefan Skoog +3
Variable flux memory motors, which employ Low Coercive Force (LCF) magnets, achieve extended high-efficiency operation through controllable magnetization states. To address the nee…
