Abstract:
In this paper, the analysis and modeling of magnetic field in 3D, of a multiphase induction motor are presented. In particular, the effects of high phases growing to infinity are studied, too. This paper describes analysis and computer experimental results of MMF in multiphase AC machines supplying by sinusoidal and nonsinusoidal currents and voltages.
   
Key Words: MMF, magnetomotive force, variable speed drives, multiphase induction motors, inverter excitation, time harmonics, spatial harmonics.
