The output of a 3-phase machine is always greater than a single-phase machine of the same size. The output will be approximately 1.5 times more than a single-phase machine.
For transmission of electrical power, a 3-phase supply requires less copper or less conducting material than that of a single-phase system for given volt-amperes and voltage ratings. Hence a 3-phase system is more economical compared to a single-phase system.
Single-phase machines are not self-starting machines. On the other hand, 3-phase machines are self-starting due to a rotating magnetic field.
The 3-phase system gives steady output and also ensures that a single-phase can be derived from it itself.
