This paper deals with d, q-axis inductance derivation and torque calculation of interior permanent magnet synchronous motor (IPMSM). Using 2-D finite element analysis (FEA), noload flux linkage and load flux linkage are investigated. With those results, the electrical angle difference between noload flux linkage and load flux linkage, L<SUB>d</SUB>(d-axis inductance) and L<SUB>q</SUB>(q-axis inductance) are calculated in each current value and current phase angle condition at rated speed. In addition, reluctance torque and magnetic torque are calculated and analyzed as well.

This paper deals with comparison and analysis for various losses of high-speed permanent magnet synchronous motor using phase current harmonic analysis. Through measured current wave, various losses are calculated and compared with losses according to current sine wave. Poynting vector, Steinmetz equation, finite element method and so on have been used to investigate the losses of high-speed permanent magnet machine.

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.
