High-speed flux-switching permanent magnet machine and comparison with other types of PM machines

Abstract

• FSPM machine has sinusoidal flux linkage, back-EMF, and rigid rotor structure that is suitable for a wide range of applications including high-speed operation • Conventional 12/10 FSPM machine requires an unfeasible value of fundamental frequency at high-speed condition. Hence, there are challenges in iron loss, magnet loss, and inverter switching losses for high-speed applications. • Dual-stator 6/4 FSPM machine has the lowest fundamental frequency requirement for three-phase operation. It achieves significantly harmonic distortion reduction in flux linkage and less torque ripple compared to conventional 6/4 FSPM machine. Therefore, dual-stator 6/4 FSPM machine has great potential for high-speed operations
