If you are wondering about the difference between 3 phase vs single stage AC motors, remember this. Single phase AC motors usually operate on a single phase way to obtain power while 3 phase AC motors operate on a three phase source of power. The single phase alternating electric current is the most typical source of power utilized by many households and non industrial businesses. It’s the power that is utilized to light homes and power TVs in THE UNITED STATES. Today, most commercial buildings in the US utilize the 3 phase alternating electric current motors due to its versatility an power density. The 3 phase AC motor is specially common in large businesses which includes in the manufacturing and industrial businesses.
Data centers today have become power intensive, to ensure that they can end up being able to offer storage and computing capabilities. It has resulted in the growth in demand of power supply to meet the needs of the data centers. The single phase alternating electric current power motor can’t meet the power needs of these data centers since it requires costly rewiring. Three stage alternating current power electric motor is economical to provide capacity to data center since it requires much 
less conductor material to provide electrical power. This explains why 3 phase alternating current motor is used in electric transmission, era and distribution in most countries globally. The single phase alternating current motor is much less reliable and more costly to be used in a national electrical power grid compared to 3 phase alternating current motor.
Both 3 phase and one phase ac motors contain two parts, namely the rotor and stator. The stator is the part of the engine, which is stationary while the rotor is simply the rotating area of the motor.
