State advantages of short pitch winding over full pitch winding in alternators. 
by

1 Answer

Answer :

Advantages of Short Pitch Winding over Full Pitch Winding in Alternators: 1) Short pitching reduces the amount of copper needed for end connection when compared with full pitched coil. 2) They improve the waveform of generated EMF i.e. generated EMF can be made approximately to sine wave more easily and the distorting harmonics can be reduced. 3) Due to the elimination of high frequency harmonics, eddy current and hysteresis losses are reduced, thereby increasing the efficiency. 4) The power quality of generated emf is improved.
