In case you are wondering about the difference between 3 stage vs single stage AC motors, just remember this. Single stage AC motors usually are powered by a single phase way to obtain power while 3 phase AC motors operate on a three phase way to obtain power. The single phase alternating electric current is the most typical source of power used by many households and non commercial businesses. It is the power that can be used to light homes and power TVs in THE UNITED STATES. Today, most commercial buildings in the US use the 3 phase alternating electric current motors because of its versatility an power density. The 3 phase AC engine is particularly common in huge businesses which includes in the manufacturing and industrial businesses.
Data centers today have grown to be power intensive, so that they can end up being able to offer storage space and computing capabilities. This has resulted in the growth in demand of power supply to meet up the needs of these data centers. The single phase alternating electric current power motor can no longer meet up with the power needs of these data centers since it requires costly rewiring. Three stage alternating current power motor is economical to provide power to data center because it requires less conductor material to provide electricity. This explains why 3 stage alternating current motor is used in electric transmission, era and distribution generally in most countries globally. The single stage 
alternating current motor is less reliable and more expensive to be used in a national electricity grid in comparison to 3 phase alternating current motor.
Both 3 phase and single phase ac motors contain two parts, namely the rotor and stator. The stator may be the part of the electric motor, which is 3 Phase Ac Motor china stationary while the rotor is simply the rotating section of the motor.
