If you are wondering about the difference between 3 phase vs single phase AC motors, just remember this. Single stage AC motors usually are powered by a single phase way to obtain power while 3 phase AC motors are powered by a three phase way to obtain power. The single stage 3 Phase Ac Motor china 
alternating current is the most common source of power utilized by the majority of households and non commercial businesses. It’s the power that is used to light homes and power TVs in North America. Today, most commercial structures in the US use the 3 phase alternating current motors due to its flexibility an power density. The 3 phase AC engine is particularly common in large businesses which includes in the production and industrial businesses.
Data centers today have become power intensive, to ensure that they can end up being able to offer storage and computing capabilities. It has led to the growth popular of power supply to meet up the needs of these data centers. The single phase alternating current power motor can’t meet the power needs of these data centers because it requires expensive rewiring. Three stage alternating current power electric motor is economical to provide capacity to data center because it requires less conductor material to provide electrical power. This explains why 3 stage alternating current motor can be used in electric transmission, era and distribution in most countries globally. The single phase alternating electric current motor is much less reliable and more costly to be utilized in a national electricity grid compared to 3 phase alternating 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 while the rotor is merely the rotating portion of the motor.
