| Single Phase Motors | Three Phase Motors |
| Can be operated anywhere as Single phase supply is Widely Available | Can be used only when three phase supply is available. |
| Efficiency is lower as a single winding has to carry all the current. | Efficiency is Higher as Three windings carry the current |
| Torque is not uniform | Torque is uniform |
| Larger in Size for the same kW rating | Smaller in Size |
| Cost is cheaper at the fractional kW range due to high volume of production | Cost is higher at low kW range. |
| Cost is higher at high kW ratings | Cost is cheaper at lower kW range. |
