In this paper, a nonlinear dq model is proposed for transient simulations of a salient-pole wound-rotor synchronous machine. Despite the nonlinearity between the flux linkage and the current, it is shown, thanks to a validation based on finite element simulations, that the new model is efficient for saturated transient state of the machine. This method allows obtaining more accurate results than classical...
The paper analyses the influence of induction machine (IM) design on rotor slotting harmonics used for sensorless control strategies. These harmonics have a direct impact on flux and rotor position estimation accuracy. Therefore prediction of their magnitude helps in selecting suitable machine designs with regard to stator/rotor slotting and winding configuration. The paper at hand focuses on the...
