This paper investigates the nonlinear inductance model of a salient Permanent Magnet Synchronous Machine. In particular, the computation of the phase inductances as function of the rotor position under different load conditions is performed through Finite Element Analysis so to enable the numerical simulation of sensorless rotor position detection algorithms. Also, a sensitivity analysis is carried out in order to evaluate the effects of geometric variation on the inductances and on the accuracy of the estimated position.

In particular, the computation of the phase inductances as function of the rotor position under different load conditions is performed through Finite Element Analysis so to enable the numerical simulation of sensorless rotor position detection algorithms. Also, a sensitivity analysis is carried out in order to evaluate the effects of geometric variation on the inductances and on the accuracy of the estimated position.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
