Industrial electric motors are used to power a wide range of applications on a global scale. The International Energy Agency (IEA) estimates that the global energy consumption by the automotive industry is up to 70% of all industrial energy, 35% of energy used in the commercial and service sectors, and 45% of all electricity generated. Electric motors are crucial to many industrial activities since each hour of downtime brought on by a motor failure costs thousands of dollars.

They are the main cause of power plants’ emissions of greenhouse gases and their damaging effects on the environment. Also, they are mostly to blame for the substantial rise in electricity consumption in emerging countries. Industrial motor energy efficiency improvements have the economic potential to increase by 20% to 30% globally, with the majority of payback times falling under three years. Around 15%, or 4.3 billion tons, of the world’s annual CO2 emissions, which total 26 billion tons, are caused by electric motors. One of the most affordable and low-risk ways to minimize greenhouse gas emissions and stop the rise in energy use is to boost energy efficiency.

Employ a powerful motor for the following reasons:

Decreased running costs.
A quieter and cooler process
Greater reliability and longer motor life
Decreased greenhouse gas emissions

Starting a Motor Analysis:

Electric motors do not typically convert all their electricity into mechanical energy. Some energy is lost due to windage, losses in the stator, rotor, and magnetic core, and friction. The motor’s performance is diminishing because of these losses.

It is obvious why and how important it is to examine energy efficiency and create minimal energy performance requirements when you consider how much energy is spent and how electric motors are used in industry.

The testing technique used affects how accurately efficiency and motor loss are evaluated. There is not a single testing method used by all global enterprises. Although the idea is straightforward, it could be challenging to measure and certify a motor’s energy efficiency using various standards.

Accepted Methods for Assessing Effectiveness Throughout the World:

The following testing techniques are widely addressed in industrial contexts:

A common technique for testing multiphase motors and generators is IEEE 112-2004. International Electrotechnical Commission (IEC) Publication 60034-2-1, Tests, “Methods for Calculating the Efficiency and Losses of Rotating Electrical Machinery,” 2014.

The JEC 37 standard for induction devices was produced by the Japanese Electrotechnical Committee. ANSI/IEEE 112-2004, IEEE Standard 112-2004

This technique includes ten different energy efficiency test methodologies. Using the most important:

simple input and output test.
test for loss-separated input and output.
Back-to-back linked machine test for loss separation.

calculation of load losses utilizing smoothed residual losses.
The Eh-star strategy

The IEC standard test falls into one of three categories:

measuring a single machine’s input-output power.
measuring the combined input and output power of two linked machines.

Losses on one machine were counted.

The extra load losses have no impact on the test processes according to Japanese JEC standard 37. By lowering the energy use of their equipment and appliances, businesses may both save money and help the environment. One of the several important economic and environmental advantages is this.
