Eddy-current loss in the rotor magnets of permanent-magnet brushless machines having a fractional number of slots per pole
TL;DR: In this article, the authors developed an analytical model for predicting the eddy-current loss in the rotor magnet of permanent magnet brushless motors, which can account for space-harmonic magnetomotive forces resulting from the winding distribution and timeharmonic MMFs due to nonsinusoidal phase currents, as well as the effect of curvature and circumferential segmentation of the magnets.
