Abstract :
A detailed representation of buried permanent magnet synchronous motors at steady state is presented. An equivalent circuit is proposed that accounts for the saliency of the machine and the particular influence of iron core losses on the machine operations. No-load as well as loaded conditions were analyzed and experimentally tested in order to describe the influence of the armature current on the rotor flux distribution. It is shown that several performances of permanent magnet motors can be predicted by the circuit.<>
