A Study on the Calculation of Flux Linkage of IPMSM through a Nonlinear Magnetic Equivalent Circuit Analysis

초록

This study describes a method for obtaining the flux linkage, which is the most important parameter in IPMSM. In order to take into account the magnetic flux saturation in the core, the nonlinear analysis approach and the MNA method, which is easily implemented using a computer algorithm, were utilized. In addition, a method for avoiding oscillating solutions when employing the MNA approach was described. In order to determine the flux linkage for each rotor position, the moving winding approach was used to determine the flux linkage for six distinct rotor locations from a single magnetic equivalent circuit. By comparing the MNA-obtained flux linkage to the findings of finite element analysis, the flux linkage's validity was confirmed.
