What is IE3 ? How is it different from IE2 and IE1?

In today's world, policies on reducing energy consumption have been discussed many times because in addition to reducing operating costs, it also helps to conserve the environment. Because reducing energy consumption is equal to reducing the amount of carbon emissions, which are an important greenhouse gas, into the system. And especially in the industrial sector that requires a very high amount of electricity to operate, it is important to pay attention to this matter.

“Motors - The most important machines that consume electricity in the world.” According to information from Motor Summit 2012, motors use 46% of the world’s electricity. That is, if we can reduce the energy consumption of motors, it will have a direct effect on reducing our overall energy consumption. One way to reduce the energy consumption of motors is to use higher efficiency motors to reduce losses in operation. Engineers must first distinguish which motors have high enough standards to save more energy. This time, we will talk about an important standard that engineers must know, which is the IE3 standard.

High Efficiency Motor (IE3) What is it?
How is it different from other motors?

IE3 motors are motors used in machinery and industry systems, but they differ in their energy efficiency standards set by the International Electrotechnical Commission (IEC). They differ from IE2 and IE1 motors in that IE3 motors have a higher energy efficiency than IE2 motors by about 10-15% and IE1 by about 20-30%.

Why IE3 motors are more efficient

• Energy loss is reduced from the steel in the stator core by using higher grades of steel produced.
• Less energy loss in the coil due to new coil design.
• Electromagnetic wave transmission is improved due to the new frame design.
• Load loss is reduced due to new rotor design.
• Mechanical losses are reduced while maintaining good cooling efficiency due to improvements to reduce the size of the cooling fan.

Now, let's see if your factory is using IE3 motors. Let's take a look and if you need more information, feel free to ask.
