As the energy requirements of single load systems are often small, all our homes, offices are given a single-stage A.C. supply only. To get appropriate working conditions using this single-phase supply, compatible Single Phase Ac Motor motors need to be utilized. Besides getting compatible, the motors need to be economical, dependable and simple to repair. One can find most of these characteristics within a phase induction motor readily. 
Similar to three-phase motors but with some modifications, single-phase induction motors are a great choice for domestic appliances. Their simple style and low cost possess attracted many applications.
Single-phase induction motors will be the simple motors which are powered by single -stage A.C. and where torque is produced because of induction of electricity due to the alternating magnetic fields
