Experimental and comparative study of mechanical and electromagnetic aspects of a high-speed permanent magnetic motor with two different magnetic materials

This paper compares permanent magnet synchronous motors with rare earth permanent magnets (PM) and those with ferrite PM, and it suggests that ferrite PM can replace rare earth PM. Therefore, the two models with the same output were compared and analyzed by comparing the mechanical and electromagnetic characteristics. Finally, the study is validated experimentally.This paper compares permanent magnet synchronous motors with rare earth permanent magnets (PM) and those with ferrite PM, and it suggests that ferrite PM can replace rare earth PM.
