Most suited for industries like

Cement | Steel | Construction | Machine Tools | Textile | Material Handling | Fertilizers | Poultry | Air-conditioning | Power

Advantages of three phase motors

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