Whats difference between a single phase & a three phase
motor?

Answer Posted / p. naik

The starting circuit of of a3-phase motor has a contactor
wherein all the 3 phases of the supply are connected to it.
Whereas in 1-phase motors only 2 phases are required & the
third input of the contactor is looped from it's own
output.The main diffrence can be spoted in the power
diagram itself.
