Hysteresis Loss in NdFeB Permanent Magnets in a Permanent Magnet Synchronous Machine

open access: yesIEEE Transactions on Industrial Electronics, 2022
Most permanent magnet (PM) loss studies consider only eddy current loss and neglect hysteresis. In this article, the hysteresis behavior of two NdFeB PM grades with different magnetic properties is assessed when applied in a PMSM. Data from vibrating sample magnetometer measurements and hysteresis modeling are used as a base.
