Picture
 1.a the winding diagram in single phase, the coil are divided into 4 
group, each group that have two coil, all the coil group are connected 
in parallel, every coil group in each phase shown by letter R for first 
phase, S for second and  T for last(see picture 1.b). First phase(blue 
color) letter range are from R1 to R8, which are R1 the beginning  and 
R2 are the end of the coil.
