Core loss estimation methods show significant variability in accuracy compared to finite element analysis results.
The study calculates core losses using empirical approximations based on the Bertotti equation and compares them against FEA outcomes.
Finite element analysis of an interior PMSM was employed to calibrate coefficients for accurate loss approximation throughout operation.
Findings provide insights for developing better algorithms and control strategies for PMSM performance optimization.
