In case you are wondering about the difference between 3 stage vs single stage AC motors, remember this. Single phase AC motors usually are 3 Phase Ac Motor china powered by a single phase source of power while 3 stage AC motors are powered by a three phase source of power. The single stage alternating electric current is the most common source of power utilized by many households and non industrial businesses. It is the power that can be used to light homes and power TVs in North America. Today, most commercial structures in the US utilize the 3 phase alternating current motors because of its flexibility an power density. The 3 phase AC motor is particularly common in huge businesses including in the production and industrial businesses.
Data centers today have become power intensive, to ensure that they can be able to offer storage space and computing capabilities. This has resulted in the growth in demand of power supply to meet the needs of these data centers. The solitary phase alternating current power motor can’t meet up with the power needs of these data centers since it requires expensive rewiring. Three phase alternating current power electric motor is economical to provide power to data center since it requires less conductor material to supply electrical power. 
This explains why 3 stage alternating current motor is utilized in electric transmission, generation and distribution in most countries worldwide. The single phase alternating current motor is much less reliable and more costly to be used in a national electricity grid in comparison to 3 phase alternating electric current motor.
Both 3 phase and single phase ac motors consist of two parts, namely the rotor and stator. The stator is the part of the electric motor, which is stationary while the rotor is merely the rotating area of the motor.
