In order to create a common system, IEC issued in October 2008 the norm IEC 60034-30. It’s a new classification sytem of efficiency that replaces the CEMEP one (to be clear, the one of “Eff.1, Eff.2, and Eff.3” motors).
It’s based on that and on the Regulation (EC) nr 640/2009 of 22 July 2009 that:
– From June 2011, the motors with efficiency lower than IE-2 will be forbidden
– From 2015, the minimum efficiency for motors from 7,5 to 375kW will be l’IE-3, and
– From 2017, the obligation of IE-3 will be extended to the motors from 0,75kW to 5,5kW
If not interest in CO2 emissions, surely, what mainly matters to the user is the BILL EFFECT: The purchase cost of a motor is about 2-3% of the total costs of its life. The balance is energy consumption costs. Comparing Eff.1 motors to Eff.2, the purchase price difference is recovered in about one year of energy saving.
We also remember the DURABILITY EFFECTS: Higher efficiency motors heat less, slowing
down the aging cycle of the insulating materials and living longer. Eff.1 motors can live
approx 40% longer than Eff.2 motors.
The problem is: can the client trust in the manufacturer’s declarations about the efficiency of the offered motors?
What does Motive do in this scenario?
– the data declared in catalogues is backed by the probative test-reports uploaded in motive web-site (each declared data, we remind it, is in fact supported, detailed and proven by such test reports)
– Eff.2 Motive motors are often offering an efficiency abundantly above the min allowed level, permits to several Eff.2 Motive motors to be already classifiable as IE-2 “high efficiency”. Before 2011, anyway, all those motors that do not yet reach IE-2 efficiency level will be improved.
– “Eff.1” motors are already available, and most of them are already IE3 “premium
efficiency”.
– The test reports end data truth of Eff1 Motive motors has been certified by IMQ,
the main Italian certification body for electrical appliances. The same, in fact,
in September 2008 has firstly inspected and qualified our internal laboratory
according to the norm IEC/ISO17025, and then supervised the internal tests on a
sampling list of Eff.1 motors, including some 6 and 8 poles in order to enclose further
values that, out of CEMEP classifications, were already established by some Countries
laws.
