Abstract

The high-flux permanent magnet and flux-barrier structure of permanent magnet synchronous machines (PMSMs) has strong magnetic saturation and harmonic components. When control algorithms for such machines are examined by performing control simulation, the use of the conventional motor model based on the voltage equation can cause problems. To avoid these problems, we introduce the technique of coupled analysis by magnetic field control and circuit simulation. Further, iron losses generated in the PMSMs can be estimated by the coupled analysis system. The iron losses under various driving conditions are calculated by the coupled analysis system and are compared with measured losses. The comparison shows that the coupled analysis system is suitable for accurately estimating the iron losses of a PMSM. © 2013 Wiley Periodicals, Inc.
