Abstract
A method and apparatus are provided for modeling an electric motor. The method includes the steps of interpolating a flux density for each angular position within an air gap of the electric motor from a predetermined air gap and tooth magnetization magnetomotive force versus air gap flux density curve, decomposing the interpolated flux density into a set of harmonic components using a fast Fourier transform and determining a flux density error function from the decomposed set of harmonic components.
