Evaluation of surface mounted PM machine's parameters on load conditions using frozen permeability method. Part. II

Abstract

This work deals with the influence of magnetic saturation on machine parameters of a surface mounted permanent magnet synchronous machine driven by an ideal six-step three-phase inverter. In this second part, a special attention is given to back-EMF calculation since the linkage flux of each phase has an abrupt change every sixty electrical degree due to the phase commutation.
