In early papers about Permanent Magnet Synchronous Machines (PMSMs) it was often stated that there are no rotor losses in PMSMs. Later, eddy current analyses for sintered permanent magnets (PMs) have been dominating the rotor loss analyses. However, in some designs also hysteresis losses can be possible in PMs. This paper uses 2D Finite Element Method (FEM) program and 2D slotless analytical model to show the main factors affecting the hysteresis loss emergence and the applicability limitations of the existing analytical approaches in evaluating the hysteresis loss. A Tooth Coil Winding PMSM prototype with external rotor topology is used in the analysis as a reference.
