How to Download IEC 60034-30-1 Standard on Efficiency Classes for AC Motors
If you are looking for a reliable and comprehensive source of information on the efficiency classes of line operated AC motors, you may want to download the IEC 60034-30-1 standard. This international standard was published by the International Electrotechnical Commission (IEC) in 2014 and is concerned with the global harmonization of energy efficiency classes for electric motors.

In this article, we will explain what the IEC 60034-30-1 standard covers, why it is important, and how you can download it in PDF format.
What is the IEC 60034-30-1 standard?
The IEC 60034-30-1 standard specifies efficiency classes for single-speed electric motors that are rated according to IEC 60034-1 or IEC 60079-0, for operation on a sinusoidal voltage supply. It establishes a set of limit efficiency values based on frequency, number of poles and motor power. It also defines four IE (International Efficiency) classes for electric motors: IE1 (standard efficiency), IE2 (high efficiency), IE3 (premium efficiency), and IE4 (super-premium efficiency).
The standard covers a wide range of products, including single and three phase motors, 2, 4, 6 or 8 poles motors, rated output from 0.12 kW to 1000 kW, rated voltage from 50 V to 1 kV, and motors designed for continuous operation at their rated power with a temperature rise within the specified insulation temperature class. It also applies to motors that are marked with any ambient temperature within the range of -20 ÂC to +60 ÂC and an altitude up to 4000 m above sea level.
The standard does not cover single-speed motors with 10 or more poles or multi-speed motors, motors completely integrated into a machine that cannot be tested separately from the machine, brake motors when the brake cannot be dismantled or separately fed, and motors designed for converter operation only.
Why is the IEC 60034-30-1 standard important?
The IEC 60034-30-1 standard is important because it provides a common framework for comparing the energy efficiency of different motor technologies and applications. It also helps manufacturers, suppliers, customers, regulators and policy makers to promote and adopt more energy-efficient solutions for electric motor systems. By using higher efficiency classes of electric motors, such as IE3 or IE4, significant energy savings and environmental benefits can be achieved.
According to the IEC, electric motor systems account for about 40% of global electricity consumption and are responsible for about 6 billion tonnes of CO2 emissions per year. Improving the energy efficiency of electric motor systems by just 10% could save about 500 TWh of electricity and reduce CO2 emissions by about 400 million tonnes per year.
