摘要: Interior permanent-magnet (IPM) machines exhibit relatively large spatial harmonics in phase voltages and high nonlinearity torque production due to both the presence of reluctance magnetic saturation stator rotor cores. To simulate real electromagnetic behavior IPM machines, this paper proposes a high-fidelity computationally efficient machine model considering saturation, harmonics, iron loss effect based on inverse solution flux linkages extracted via finite-element analysis (FEA). Neither FEA nor derivative computation is involved time-stepping simulation; thereby, proposed numerically robust. The fidelity validated by experimental results.
