More common is 3 phase due to small, lighter, cheaper and with same amount of power. Better efficiency, less copper to transmit power, can be used in industrial and domestic, and can take more load than single phase.

In our daily life, Ac single-phase motor is also used. Like a ceiling fan, the capacitor starts the motor in house pump, exhaust fan, blower for kitchen etc. So, the single phase induction motor mostly used.

The most common type of I.M is 2 phase motor since we can't get 3 phase supply in domestic uses. So 2 phase motor is most common motor we find.

Moreover, 3 phase IM are having self-starting torque, unlike synchronous motors. Single phase IM need auxiliaries for rotating.

Because of variable speed 3-phase induction motors are mostly used.

Both single and 3 phase are commonly used motors.

Because 3phase IM is self-starting.
