How to calculate back pitch, front pitch, commentator pitch?, Electrical Engineering

Assignment Help:

Q. A 6 - pole, DC armature with 36 slots and 2 coil - slides/slot is to be wave wound (double layer). Calculate the back pitch, front - pitch and commentator pitch. How many dummy coils, if any are required? 

Ans. 

Given

                           C = 36

 

                           P = 6

 

                           C = P/2Yc ± 1

 

                           36 = 6/2 Yc ± 1

 

                           36 = 3Yc ± 1

 

   Let                    Y = 12 then

 

                            C = 3 ×12-1

 

                                = 35

 

SO we choose C = 35 which actually 36 coils be accommodate

 

                           Yes = S/P = 36/6 = 6

 

                           YB = 2YCS + 1

 

                          YB = 2 × 6 + 1

 

                          YB = 13

 

                         YF = 2Y - YB = 2 ×12 - 13 = 11
