A New Standard in Motor Efficiency
In this age of climate change and energy efficiency the EU have imposed strict new legislation governing the manufacture of industrial electric motors which will see an increase in the minimum permitted motor efficiency.
With as much as 70% of industry's energy consumption being directly attributed to electric motors, the UK Government estimate that these changes will provide savings in the region of £200 million per year to UK businesses, as well as saving at least 1 million tonnes of CO2.
What is the EU MEPS Scheme?
The EU MEPS (European Minimum Energy Performance Standard) scheme sets mandatory minimum efficiency levels for electric motors introduced into the European market.
The scheme covers 2, 4 and 6 pole single speed, three-phase induction motors from 0.75kW to 375 kW, rated up to 1000 Volts.
The mandatory EU MEPS Scheme is replacing the voluntary CEMEP scheme. The EU MEPS Scheme defines the following efficiency classes according to the new IEC 60034-30 standard:
|Old CEMEP Scheme||New EU MEPS Scheme|
|Super Premium Efficiency||IE4|
What's already changed?
- On 16 June 2011 the minimum efficiency requirement changed to IE2 covering 0.75 - 375kW motors
Changes coming in the near future
- 1 January 2015 - Minimum efficiency requirement at IE3 for 7.5 - 375kW motors alone, or IE2 level if fitted with a variable speed drive (inverter)
- 1 January 2017 - Minimum efficiency requirement at IE3 for 0.75 – 375kW motors alone, or IE2 level if fitted with a variable speed drive (inverter)
ERIKS Total Cost of Ownership
It has been found that 20% of the UK's total energy consumption comes from industrial applications and a massive 70% of the UK's industrial consumption is from electric motors.
Showing just how major this issue really is for the environment. Energy efficiency in motors is a significant way in which industrial companies can save huge amounts of money and energy, while helping to improve the environment.
The ERIKS Total Cost of Ownership Calculator helps people work out whether they should repair, replace or upgrade by displaying the total cost of their motor. for more information on the calculator and for a link to try it out yourself.
