This paper presents a method to calculate motor parameters considering magnetic nonlinearity in interior permanent magnet synchronous motors (IPMSM). To analyze motor characteristics by using equivalent circuits, inductance and iron loss resistance, which are affected critically magnetic saturation, are obtained by using static finite-element analysis. For a fabricated IPMSM, input current and motor characteristics such as torque and efficiency are calculated, and the proposed method is verified by the comparison of calculated and experimental results
