“…The error between the analytically calculated, experimental, and FEM-modeled inductance values is about 17%. The analytical model does not take into account the excessive saturation of the teeth heads and the cross-saturation effects, which can be accurately taken into account only by the FEM [28], [29]. If semimagnetic slot wedges are used, the saturation at the stator teeth heads is decreased, which can be also accurately estimated only by the FEM.…”

Abstract-Analytical calculation methods for all the major components of the synchronous inductance of tooth-coil permanentmagnet synchronous machines are reevaluated in this paper. The inductance estimation is different in the tooth-coil machine compared with the one in the traditional rotating field winding machine. The accuracy of the analytical torque calculation highly depends on the estimated synchronous inductance. Despite powerful finite element method (FEM) tools, an accurate and fast analytical method is required at an early design stage to find an initial machine design structure with the desired performance. The results of the analytical inductance calculation are verified and assessed in terms of accuracy with the FEM simulation results and with the prototype measurement results.Index Terms-Fractional slot winding, inductance calculation, leakage inductance, permanent-magnet synchronous machine (PMSM), tooth coil.

-This Paper analyzes the characteristics of the WRSM in high-speed operation range. To verify the control characteristics of various WRSM models, the relative position of the central point of current limit circle and voltage limit ellipse is defined as M value and 3 models according to M max value are designed through inductance change. Through the designed models, the current control method of 3-variables control for maximum power especially in high-speed operation range is presented.

“…The machine electrical parameters must be identified in order to calculate the aforementioned LUTs. FEM analysis [26], [27] or experimental procedures [27], [28] are usually employed, from where electric machine d-and q-axis fluxes are obtained. Permanent magnet flux and d-and q-axis inductances can be calculated from these fluxes.…”

“…However, LUT approaches tune the control algorithm for an specific set of electrical parameters and may eventually loss control under parameter variations due to an incorrect FW regulation, i.e., exceeding the stator voltage limit and leading to an uncontrolled energy regeneration [32]. The high non-linearities caused by the magnetic saturation effect [27] together with electrical parameter variations due to machine ageing, manufacture tolerances and temperature dependency confirm the importance of relying on a robust control strategy that ensures the correct operation of the EV drive during its whole lifecycle.…”
