In case you are wondering about the difference between 3 stage vs single phase AC motors, just remember this. Single phase AC motors usually are powered by a single phase way to obtain power while 3 phase 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 the majority of households and non commercial businesses. It’s the power that is utilized to light homes and power TVs in North America. Today, most commercial buildings in the US utilize the 3 phase alternating current motors because of its flexibility an power density. The 3 phase AC engine is specially common in large businesses which includes in the manufacturing and industrial businesses.
Data centers today have become power intensive, to ensure that they can become able to offer storage and computing capabilities. It has led to the growth in demand of power supply to meet up the needs of the data centers. The solitary phase alternating electric current power motor can no longer meet the power needs of the data centers since it requires expensive rewiring. Three 
stage alternating current power motor is economical to provide power to data center since it requires much less conductor material to supply electrical power. This explains why 3 phase alternating current motor can be used in electric transmission, era and distribution in most 3 Phase Ac Motor china countries globally. The single phase alternating electric 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 contain 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 part of the motor.
