Abstract

Analytical investigation shows that, the MMF space harmonic orders of the six-phase winding with ẟ equal to 30 electrical degrees, being h = 12k± 1 compared with h 6k ± 1 for the conventional three-phase winding. On the other hand, the six-phase winding with 8 equal to 60 electrical degrees shows the same MMF space harmonic contents of the conventional three-phase winding. 
 
Goerge's vector diagram has been used as a graphical method for plotting the MMF produced by the six-phase windings. From which, the instantaneous values of the MMF over the different teeth could be found. Accordingly, a computer program is implemented to give the fundamental and higher space harmonics for each case discussed above. 
 In order to verify the computer program results, previously published space harmonic analysis for a three-phase winding with q = 2 , confirms the accuracy of the computer program used for the analysis presented
   in this paper.
