The importance of extensive optimizations duringthe design of electric machines entails a need for fast and accuratesimulation tools. For that reason, Fourier-based analytical modelshave gained a lot of popularity. The problem, however, is thatthese models typically require a current density as input. Thisis in contrast with the fact that the great majority of moderndrive trains are powered with the help of a pulse-width modulatedvoltage-source inverter. To overcome that mismatch, this paperpresents a coupling of classical Fourier-based models with theequation for the terminal voltage of an electric machine, atechnique that is well known in finite-element modeling but hasnot yet been translated to Fourier-based analytical models. Botha very general discussion of the technique and a specific exampleare discussed. The presented work is validated with the help ofa finite-element model. A very good accuracy is obtained.
