This paper deals with d, q-axis inductance derivation and torque calculation of interior permanent magnet synchronous motor (IPMSM). Applying equivalent magnet circuit, magnetic flux linkage and d, q-axis inductance are obtained. With those results, magnetic torque and reluctance torque are calculated. In addition, this results are compared and analyzed with 2-d finite element analysis (FEA) to validate this paper.
