METHODS OF CALCULATION 



But a winding with six coils may also be realized symmetrically 

 following the plan of Fig. 16, from which two new curves i6a and i6b 

 are obtained. The table also indicates the value of the coefficients 

 thereby deduced. 



TABLE V 



EMPIRICAL COEFFICIENTS 

 Three-phase winding with three separate coils per pair of poles. 



TABLE VI 



EMPIRICAL COEFFICIENTS 

 Three-phase distributed winding, 3 or 6 long coils per pair of poles. 



Here again it is seen that the direct reactions increase while the 

 transverse reactions diminish when the breadth of the flux (larger 

 than the pole) diminishes. It is moreover determined that the reac-
