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

Impact of machine magnetization state on permanent magnet losses in permanent magnet synchronous machines [PDF]
Permanent magnet synchronous machines (PMSMs) operation above based speed is typically achieved by injecting negative d-axis current to produce flux weakening. However, this increases permanent magnet (PM) losses, reducing therefore the machine efficiency.
