Abstract

Eddy current losses calculations in permanent magnets (PM), using 3D analytical and numerical methods are presented. Axial and circumferential segmentation effects on the reduction of eddy currents are investigated. The eddy currents are induced by the stator magnetic field space harmonics, caused by the winding distribution and the slot opening at sinusoidal current supply. Computations are done for two different three phase PM synchronous machines with surface mounted magnets and concentrated stator windings.
