The problem is complicated because the presence of periodic component leads to problems of nonlinear. This procedure allows the direct determination of the Fourier spectra of the most important volumes describing the synchronous machine. Sample calculations were performed for a synchronous motor operating in the state of synchronism and fixed mechanical load torque varying periodicaly at a specifed course.
