摘要:This paper presents the characteristic analysis of interior permanent-magnet synchronous motors (IPMSMs) considering magnetic saturation. In IPMSM with magnetic saturation, the individual flux from the permanent magnet (PM) and current exists, and the linear combination is not maintained. A nonlinear finite-element analysis, wherein the PMs and current are excited simultaneously, is performed. Then, the flux linkage data in each armature current and current angle are recorded, which are calculated by using the dynamic equation. Based on the analyzed results from electromagnetic field characteristic analysis, the equivalent circuit parameters are derived, and the modeling of both IPMSM and controller system is performed to predict its operating characteristics. Finally, the analysis results of the designed IPMSM are compared with measured results, and the validity of the analysis considering magnetic saturation of the IPMSM is confirmed.
