Mandatory IE3 electric motors appearing in OEM machines
Plant Engineer, January 14, 2015
From this month (1 January 2015), premium-efficiency IE3 motors are compulsory for all new machines in the range 7.5—375kW under EC 640/2009, the EU MEPS (Minimum Energy Performance Standard) regulations.
IE2 motors are no longer permitted (beyond notified exceptions, such as ATEX motors) for sale within the EU unless used with a variable speed drive.
This changes the former requirement (the first phase of the scheme, implemented in June 2011), which prescribed high-efficiency IE2 for motors with a rated output from 0.75 to 375kW.
The new ruling will be extended in the next phase to include motors down to 0.75kW, from 1 January 2017 – again with the proviso that IE2 be permitted for VSD-based applications.
