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 for the particular influence of iron core losses on the machine operations. Both no-load and loaded conditions are analyzed and experimentally tested in order to describe the influence of the armature current on the rotor flux distribution. Experimental tests on a 2 HP buried permanent magnet machine are presented to validate the proposed approach
