Three-Phase Systems in Power Applications - Engineering

Q1:

The most common type of ac motor is the

A single-phase induction motor

B two-phase induction motor

C three-phase induction motor

D two-phase squirrel-cage motor

ANS:C - three-phase induction motor

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.
