Abstract

The high-flux permanent magnet and flux-barrier structure of permanent magnet synchronous machine (PMSM) has strong magnetic saturation and harmonics 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 of the magnetic-field-control/circuit simulation. Further, iron losses generated in PMSM can be estimated by the coupled analysis system. The iron losses at various driving conditions are calculated by the coupled analysis system and are compared with measured losses. The comparison results show that the coupled analysis system is suitable for accurately estimating the iron losses of PMSM.
