Novel Modeling Approach for Iron Loss of <i>dq</i>-axis Equivalent Circuit Model of Interior Permanent Magnet Synchronous Motor

Analytical models of interior permanent magnet synchronous motors (IPMSMs) use dq-axis equivalent circuits. Accurate prediction of IPMSM performance requires a) mathematical modeling of the circuits used to implement different electromagnetic phenomena inside the motor and b) accurate estimation of the equivalent circuit parameters. Therefore, accurately calculating the magnitude of the dq-axis flux linkages from experimental data is essential; however, the influence of iron loss on flux linkage calculation has not been reported yet.
