Single 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 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 motor.

The efficiency of single phase induction motors is less as compare it to the three-phase induction motors.
