In case you are wondering about the difference between 3 stage vs single phase AC motors, remember this. Single stage AC motors usually are powered by a single phase source of power while 3 
stage AC motors are powered by a three phase way to obtain power. The single phase alternating electric current is the most common source of power utilized by many households and non 3 Phase Ac Motor industrial businesses. It’s the power that is utilized to light homes and power TVs in THE UNITED STATES. Today, most commercial buildings in the US utilize the 3 phase alternating electric current motors due to its flexibility an power density. The 3 phase AC electric motor is particularly common in huge businesses including in the manufacturing and industrial businesses.
Data centers today have become power intensive, to ensure that they can become able to offer storage space and computing capabilities. This has led to the growth popular of power supply to meet up the needs of the data centers. The single phase alternating current power motor can’t meet the power needs of the data centers since it requires expensive rewiring. Three stage alternating current power motor is economical to supply power to data center since it requires much less conductor material to provide electrical power. This explains why 3 phase alternating current motor can be used in electric transmission, era and distribution generally in most countries worldwide. The single phase alternating electric current motor is less reliable and more costly to be utilized in a national electricity grid in comparison to 3 phase alternating electric current motor.
Both 3 phase and solitary phase ac motors contain two parts, namely the rotor and stator. The stator is the part of the motor, which is stationary while the rotor is merely the rotating part of the motor.
