|TIME - SPATIAL MMF FOR SIX PHASE AC MOTORS|
In this paper, the analysis and modeling of magnetic field of a six-phase induction motor are presented. In particular, the effects of different, rectangular supply currents, mechanical and electrical asymmetry are studied. The results are clearly seeing on 3D figures where third dimension is time of one reverse machine field.
