The Energy using Products (EuP) directive for electric motors (EC640/2009) sets strict new requirements for energy efficiency in industrial applications. The directive is relevant for nearly all electric motors in the power range of 0.75 kW to 375 kW, and introduces a new mandatory scale for their efficiency. This scale starts with IE1 as the lowest and current efficiency standard and has IE3 as the highest.

The directive came into effect in mid-2011 and will gradually increase efficiency requirements in a 3-stage process.

All motors must meet the IE2 high efficiency standard and all motors below this will be prohibited.

All 7.5 kW to 375 kW motors must meet the IE3 standard or meet the IE2 standard and be equipped with a variable frequency drive (VFD).

In the last stage of the directive all 0.75 kW to 375 kW norm motors must meet the IE3 standard  - or meet the IE2 standard and be equipped with a variable frequency drive (VFD).

It is estimated that by 2020, €9 billion and 5% of Europe's total electricity consumption will have been saved because of the directive.

A better financial and environmental choice
On average 85% of a normal pump system's Life Cycle Cost (LCC) is energy costs. Switching to high-efficiency motor technology can mean a LCC reduction of up to 50% - not to mention a serious reduction in environmental impact. And while high-efficiency motor technology can initially cost a little more, the payback period for this difference is usually within 2 years. After that it's just energy and cost saving all the way!
