The effect of losing one-phase or more of the excitation system on the space MMF harmonics has been investigated for two types of six-phase stator windings ; by means of Goerge's vector diagram. The scope of this work covers the various changes in the resultant MMF waveforms that occur due to one-phase, or two-phase, or three-phase being opened. Consequently, an insight into avoiding the modes of operation which provide an objectional harmonic contents is given. The results obtained recommend to use the six-phase winding with phase spread , ẟ , eaual to 60 , in order to improve the overall reliability with one phase being opened ; the most common failures occurred.
