In case you are wondering about the difference between 3 phase vs single stage AC motors, just remember this. Single stage AC motors usually operate on a single phase source of power while 3 phase AC motors operate on a three phase way to obtain power. The single phase 3 Phase Ac Motor china alternating current is the most typical source of power used by the majority of households and non commercial 
businesses. It's the power that can be used to light homes and power TVs in North America. Today, most commercial buildings in the US utilize the 3 phase alternating electric current motors due to its flexibility an power density. The 3 phase AC electric motor is specially common in huge businesses including in the production and industrial businesses.
Data centers today have grown to be power intensive, so that they can end up being able to offer storage and computing capabilities. This has led to the growth in demand of power supply to meet the needs of these data centers. The single phase alternating current power motor can't meet the power needs of these data centers since it requires expensive rewiring. Three phase alternating current power motor is economical to provide power to data center because it requires much less conductor material to provide electricity. This explains why 3 stage alternating current motor is utilized in electric transmission, generation and distribution generally in most countries globally. The single phase alternating current motor is 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 single phase ac motors consist of two parts, namely the rotor and stator. The stator is the part of the motor, which is stationary as the rotor is simply the rotating section of the motor.
