摘要：

In this paper, the classical linear model of a permanent-magnet synchronous motor (PMSM) is modified by adding d-and q-axis harmonic inductances so that the modified model can consider nonlinearities present in an interior permanent magnet (IPM) motor. Furthermore, a method has been presented to assess the effect of saturation and cross-saturation on constant torque curves of a PMSM. Two IPM motors with two different rotor topologies and different specifications are designed to evaluate the effect of saturation on synchronous and harmonic inductances and on the operating points of the machines.
