A Study on Magnetization Yoke Design for Post-Assembly Magnetization Performance Improvement of a Spoke-Type Permanent Magnet Synchronous Motor

open access: yesMachines, 2023
Permanent magnet synchronous motors (PMSMs) are highly affected by magnetization, which determines the magnetization level in the permanent magnet (PM). There are three main magnetization methods: single-unit, stator coil, and post-assembly magnetization.

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

open access: yesAIP Advances, 2020
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

Giant coercivity of dense nanostructured spark plasma sintered barium hexaferrite

open access: yes, 2011
Due to the limited rare-earth elements resources, ferrite magnets need to be improved drastically. Ideally, for a true hard magnet, the coercive field should be larger than the saturation magnetization, which is not yet realized for ferrites.
