If you are wondering about the difference between 3 stage vs 3 Phase Ac Motor china Single stage AC motors, remember this. Single stage 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 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 
can be 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 flexibility an power density. The 3 phase AC motor is specially common in huge businesses which includes in the production and industrial businesses.
Data centers today have become power intensive, so that they can be able to offer storage space and computing capabilities. It has resulted in the growth in demand of power supply to meet up the needs of the data centers. The one phase alternating electric current power motor can’t meet up with the power needs of these data centers since it requires costly rewiring. Three stage alternating current power motor is economical to provide power to data center because it requires less conductor material to provide electricity. This explains why 3 stage alternating current motor can be used in electric transmission, era and distribution generally in most countries globally. The single phase alternating electric current motor is much less reliable and more expensive to be used in a national electricity grid in comparison 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 electric motor, which is stationary as the rotor is simply the rotating part of the motor.
