Flux Linkage, Torque, and Iron Loss Data for a 100 kW Externally Excited Synchronous Machine

This data publication provides finite element analysis (FEA) results for a salient-pole, \(100\) kW externally excited synchronous machine (EESM). The file "Parameters.mat" contains machine and operating parameters, including the pole pair number \(p\), DC-link voltage \(u_\mathrm{dc}\), maximum stator current \(i_{\mathrm{s,max}}\) (in \(A_\mathrm{rms}\)), maximum field current \(i_{\mathrm{f,max}}\), as well as the stator and field winding resistances \(R_\mathrm{s}\) and \(R_\mathrm{f}\), specified at the corresponding winding temperatures \(\vartheta_{R_\mathrm{s}}\) and \(\vartheta_{R_\mathrm{f}}\), respectively. The file "Tables.mat" includes multidimensional lookup tables for the flux linkages \(\psi_\mathrm{d}\), \(\psi_\mathrm{q}\), and \(\psi_\mathrm{f}\), as well as the electromagnetic torque \(T_\mathrm{em}\), each expressed as functions of the current components \(i_\mathrm{d}\), \(i_\mathrm{q}\), and \(i_\mathrm{f}\). \(\psi_\mathrm{d} = f(i_\mathrm{d}, i_\mathrm{q}, i_\mathrm{f})\)\(\psi_\mathrm{q} = f(i_\mathrm{d}, i_\mathrm{q}, i_\mathrm{f})\)\(\psi_\mathrm{f} = f(i_\mathrm{d}, i_\mathrm{q}, i_\mathrm{f})\)\(T_\mathrm{em} = f(i_\mathrm{d}, i_\mathrm{q}, i_\mathrm{f})\) In addition, iron loss data \(P_\mathrm{fe}\) are provided as a function of the current components and the mechanical speed \(n_\mathrm{mech}\). \(P_\mathrm{fe} = f(i_\mathrm{d}, i_\mathrm{q}, i_\mathrm{f}, n_\mathrm{mech})\) It should be noted that currents and flux linkages are given in the power-invariant reference frame. For visualization and inspection of the lookup tables, the MATLAB script "Plot_Tables.m" is included. The provided dataset is intended for the parameterization of EESM simulation models used in controller development and validation within model-in-the-loop (MIL) and hardware-in-the-loop (HIL) environments.
