As 
the power requirements of single load systems are usually small, all our homes, offices are given a single-stage A.C. supply just. To get correct working circumstances using this single-phase supply, compatible motors have to be used. Besides being compatible, the motors need to be economical, reliable and simple to repair. One will discover most of these characteristics in one phase induction motor readily. Similar to three-stage motors but with some modifications, single-phase induction motors certainly are a great choice for household appliances. Their simple style and low cost have attracted many applications.
Single-phase induction motors will be the basic motors which are powered by single -phase A.C. and where Single Phase Ac Motor torque is produced because of induction of electricity due to the alternating magnetic fields
