Dynamic Characteristic Analysis of Interior Permanent Magnet Synchronous Motor Considering Varied Parameters by Outer Disturbance Based on Electromagnetic Field Analysis

This paper analyzes the dynamic characteristics of interior permanent magnet synchronous motor (IPMSM), taking in to account the outer disturbance to a motor system. 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 also performed to predict its operating characteristics. In particular, in our simulation, the dynamic characteristics according to inductance variation by an outer disturbance are specifically analyzed, and all the simulation results are experimentally validated showing well corresponded results.
