Three-phase IEC metric AC motors is most common form of motor which is used in everyday life from pumping water up the overhead tank to power plant boiler feed pumps. These motors are very flexible to use and matches the load demand almost for everything. The most widely used Induction Motors are very important for many industries due to their load bearing capacity and flexibility. These motors,unlike synchronous motors, slip when compared to the stator current field. They are generally used for various types of pumps, compressors and acts as prime movers for many machineries.
