If you are wondering about the difference between 3 stage vs 3 Phase Ac Motor china single stage AC motors, just remember this. Single phase AC motors usually are powered by a single phase way to obtain power while 3 stage AC motors operate on a three phase source of power. The single phase alternating current is the most common source of power used by most 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 current motors because of its versatility an power density. The 3 phase AC motor is specially common in huge businesses including in the manufacturing and industrial businesses.
Data centers today have grown to be power intensive, so that they can be 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 solitary phase alternating electric current power motor can no longer meet up with the power needs of the data centers because it requires expensive rewiring. Three phase alternating current power engine is economical to supply power to data center since it requires much less conductor material to provide electrical power. This explains why 3 stage alternating current motor can be used in electric transmission, era and distribution generally in most countries worldwide. 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 electric 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 motor, which is stationary while the rotor is simply the rotating area of the motor.
