In an exemplary embodiment of the method, magnetic analysis includes selecting and loading (104) electrical machine manufacturing data, such as a stator and rotor geometry and winding design, for example. If the power supply is a voltage source, stator currents are estimated (108). If the power supply is a current source, stator currents are computed. Using the stator current, estimated or computed, a magnetomotive force spectrum is computed (110). From the spectrum, a permeability distribution is computed and tested for magnetic convergence. When there is both magnetic and voltage convergence, the analysis is complete, otherwise the process is repeated.
