If you are wondering about the difference 3 Phase Ac Motor china between 3 phase vs single stage AC motors, just remember this. Single phase AC motors usually operate on a single phase source of power while 3 stage AC motors are powered by a three phase source of power. The single phase alternating electric current is the most common source of power used by the majority of households and non industrial businesses. It’s the power that is used to light homes and power TVs in 
North America. Today, most commercial buildings in the US use the 3 phase alternating electric current motors due to its versatility an power density. The 3 phase AC engine is specially common in huge businesses including in the manufacturing and industrial businesses.
Data centers today have become power intensive, so that they can become able to offer storage space and computing capabilities. It 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 no longer meet the power needs of the data centers since it requires costly rewiring. Three stage alternating current power motor is economical to supply capacity to data center since it requires much less conductor material to supply electrical power. This explains why 3 stage alternating current motor is utilized in electric transmission, era and distribution in most countries worldwide. The single phase alternating current motor is much less reliable and more expensive to be used in a national electrical power grid compared 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 engine, which is stationary as the rotor is simply the rotating part of the motor.
