| Popis: | The classical dq-axes model of permanent magnet synchronous machines (PMSM) uses linear approximation. This was not an issue in earlier versions of PMSM drivesbecause they mostly used surface magnet motors. With the arrival of interior permanent magnet (IPM) machines, which use reluctance torque along with magnettorque, the accuracy of linear models are found to be insufficient. In this work, the effect of air gap flux harmonics is included in the classical model of PMSM using dand q-axes harmonic inductances. Further, a method has been presented to assess the effect of saturation and cross-saturation on constant torque curves of PMSM. Twointerior permanent magnet motor with two different rotor topologies and different specifications are designed to evaluate the effect of saturation on synchronous andharmonic inductances, and operating points of the machines. |
