<p>Methods and apparatus for performing electrical machine electromagnetic analysis in the frequency domain are described. The method and apparatus are applicable to both poly phase and single phase electrical machines whether balanced or unbalanced (source, windings, magnetics, harmonics). 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 source is a voltage source, stator currents are estimated (108). If the power source 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. <IMAGE> <IMAGE></p> |
