Why AC induction motor is most widely used motor in the industry?

The self-starting, reliable and cost-effective nature of three-phase squirrel-cage induction motors make them the first choice for industrial drives.

Electric motors are critical components in a wide range of industrial applications, from manufacturing to transportation. In fact, electric motors account for more than 40 percent of global industrial electricity consumption. One type of motor that is particularly popular in industry is the AC induction motor, accounting for more than 90 percent of all motors used in industrial applications. So, what makes AC induction motors so widely used in the industry?


First, AC induction motors are reliable and have a long life. Their simple design has no brushes, commutators or slip rings, which means they have fewer moving and wearing parts. This results in less maintenance and lower operating costs. Additionally, their rugged design enables them to withstand extreme conditions, making them ideal for use in demanding industrial environments.

Another key advantage of AC induction motors is their efficiency. They are very efficient at converting electrical energy into mechanical energy, which means they use less power and generate less heat than other types of motors. Not only does this reduce energy costs, it also increases their lifespan since they experience less thermal stress.

A key feature that sets AC induction motors apart is their ability to operate at variable speeds. By varying the frequency of the AC power supplied to the motor, the speed of the motor can be adjusted to meet the requirements of the application. This makes them ideal for a wide variety of industrial applications, from fans and pumps to conveyor belts and machinery.


Additionally, AC induction motors are cost-effective. They cost less to manufacture than other types of motors, making them a popular choice for applications requiring more than one motor. Additionally, their reliability, efficiency and low operating costs make them a cost-effective choice throughout their lifetime.

Considering all these advantages, it is no surprise that AC induction motors are widely adopted in a range of industrial applications. They are preferred by many industries including oil and gas, mining, automotive and manufacturing.

All in all, AC induction motors are reliable, efficient, adaptable and cost-effective, making them the motor of choice for many industrial applications. Its simple design, robust construction and ability to operate at variable speeds make it an integral part of many industries. As technology develops, it is likely that AC induction motors will continue to be widely used in various industrial applications for many years to come.
