IEC 60034-30

global standard for the definition of energy classes

At present there are various standards of efficiency for asynchronous motors in the various regions and countries throughout the world. There are also great differences, whether these are standards, i.e. a recommendation, or a statutory regulation. In addition to the various standards and laws for efficiency classes there is a wide range of different test methods for the determination of efficiency. Therefore, an international comparison of individual efficiency classes is not only difficult; the certification of motors for individual markets is also very expensive.

Because of this, the IEC has developed a new standard which is intended to harmonize efficiency classes throughout the world. The new standard IEC 60034-30-1:2014 is to replace the different national systems. At the same time, with the IEC 60034-2-1:2007 standard, a new procedure for the measurement of efficiency has been introduced which also contributes to international harmonization.

Because of these legal requirements, not only are users compelled to use energy-efficient drive units, but manufacturers are also obliged to produce optimum efficiency drive units, which results in enormous costs and a logistical challenge.
