Eddy Current Losses in Solid Pole Shoes of Synchronous Machines at No-Load and on Load

Abstract

An improved method of calculation is described which the eddy current reaction and the variable permeability of the solid pole are taken into account. At no-load, the saturation of the stator teeth is fully considered and shows that tooth-ripple harmonics are increased by it. On load, the stator MMF harmonics of integral-slot windings are determined and added with due regard of their phase shift.
