omparison between Single Phase and Three Phase Induction MotorsSingle phase induction motors are simple in construction, reliable and economical for small power rating as compared to three phase induction motors.The electrical power factor of single phase induction motors is as low as compared to three phase induction motors.For the same size, the single-phase induction motors develop about 50% of the output as that of three phase induction motors.The starting torque is also low for asynchronous motors/single phase induction motors.The efficiency of single phase induction motors is less compared to that of three phase induction motors.Single phase induction motors are simple, robust, reliable and cheaper for small ratings. They are available up to 1 KW rating
