Failure analysis on Nd-Fe-B under the multi-physical field coupling of permanent-magnet synchronous machines

In this paper, the Tesla meter and magnetic force microscope were used to study the open-circuit remanence and magnetic domain structure of Nd-Fe-B permanent magnets (PMs) in high-power density permanent magnet synchronous motors (PMSMs). An experimental platform was built to simulate the internal d...
