The IEC has developed standardised regulations that propose to unify electric motor efficiency classes worldwide.

At present there are a multitude of standards of efficiency for synchronous motors that differ according to region and country worldwide. In addition to the varying standards and regulations for motor efficiency classes there are also a diverse range of testing methods to determine efficiency. As a result, a global comparison of individual efficiency classes can be extremely challenging and the cost of certification of electric motors for individual markets significant.

The IEC’s new standard IEC 60034-30:2008 replaces the different international classifications. In conjunction with this a new procedure for the measurement of efficiency has been introduced which also encourages international synchronisation.

Legal requirements now command that operators use energy-efficient drive units and manufacturers are obligated to provide optimum efficiency drive units. This can result in significant costs and can be logistically problematic.

The current standard international requirements can be found on the NORD Drivesystems website.
