Answer Posted / m. b. shirsat
all the previous answers added together gives correct
answer. in three phase motor phases are already split and
produce resultant torque to rotate or start motor. Single
phase produce zero resultant torque and needs to split the
phase which is done by introducing capacitor in starting
winding.
