Electromagnetic analytical modelling of permanent magnets machine in view of their optimal design

This article present a modelling method well adapted to the study of brushless permanent magnet machines used in high speed drives. The issue of the proposed technique lies on the possibility of taking into account the induced currents flowing in the conductive parts of the machine. This modelling integrates different type of rotor and stator current density. So the basic principles and the validation of this method were given in this paper.
