Analytical Estimation of Rotor Loss Due to Stator Slotting of Synchronous PM Machines

Abstract : In this paper, we analyze the rotor eddy currents losses provoqued by the stator slot harmonics developed in the permanent magnets or pole pieces of synchronous machines. An analytical approach is presented to evaluate the effect of slot ripples on rotor field and losses calculation. This analysis is then tested by 2D/3D finite element (FE) calculation on a mock model. The results show a good agreement on loss calculations when skin effect is negligible and the magnet is considered.
