In case you are wondering about the difference between 3 stage vs single phase AC motors, remember this. Single phase AC motors usually operate on a single phase source of power while 3 phase AC motors operate on a three phase way to obtain power. The single stage 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 THE UNITED STATES. 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 motor is particularly common in large 3 Phase Ac Motor china businesses including in the manufacturing and industrial businesses.
Data centers today have grown to be power intensive, to ensure that they can end up being able to offer storage and computing capabilities. It has resulted in the growth in demand of power supply to meet the needs of these data centers. The one phase alternating current power motor can no longer meet up with the power needs of these data centers since it requires expensive rewiring. Three phase alternating current power motor is economical to supply power to data center because it requires less conductor material to supply electrical power. This explains why 3 stage alternating current motor is used in electric transmission, 
era and distribution generally in most countries worldwide. The single stage alternating current motor is much less reliable and more costly to be used in a national electricity grid compared to 3 phase alternating current motor.
Both 3 phase and solitary phase ac motors consist of two parts, namely the rotor and stator. The stator may be the part of the motor, which is stationary as the rotor is merely the rotating area of the motor.
