If you are wondering about the difference between 3 stage vs 3 Phase Ac Motor china single phase AC motors, remember this. Single stage AC motors usually operate on a single phase way to obtain power while 3 stage AC motors operate on a three phase source of power. The single stage alternating current is the most common source of power utilized by most households and non industrial businesses. It’s the power that is 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 specially common in huge businesses including in the production and industrial businesses.
Data centers today have become power intensive, so that they can end up being able to offer storage and computing capabilities. This has resulted in the growth in demand of power supply to meet up the needs of these data centers. The solitary phase alternating current power motor can no longer meet the power needs of the data centers since it requires expensive rewiring. Three phase alternating current power motor is economical to provide capacity to data center because it requires much less conductor material to supply electricity. This explains why 3 stage alternating current motor can be used in electric transmission, generation and distribution generally in most countries globally. The single stage alternating electric current motor is much 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 one phase ac motors contain two parts, 
namely the rotor and stator. The stator is the part of the electric motor, which is stationary as the rotor is simply the rotating part of the motor.
