In Europe, a voluntary agreement coordinated by CEMEP (European association of motors and automation products manufacturers) and signed by motor manufacturers in 1998 established the EFF3, EFF2 and EFF1 classifications for motor efficiency (EFF3 being the lowest efficiency and EFF1 the highest).
However, despite implementation of this voluntary agreement there was no obligation whatsoever for users to buy EFF1 motors although in some countries, such as the UK, Capital Allowance Programmes were created to stimulate efficiency minded customers to purchase EFF1 motors.
But this will change starting June 11th 2011 with the 2005/32/EC Ecodesign Directive that established minimum efficiency requirements for electric motors. This Directive is based on the IEC 60034-30:2008 harmonized efficiency levels standards IE1 (Standard Efficiency), IE2 (High Efficiency) and IE3 (Premium Efficiency).
Also, the IEC 60034-30 standard defines that motors must be tested according to IEC 60034-2-1:2007, recognized as a lower uncertainty testing method standard. Additionally, the European Ecodesign is the first Directive that extends beyond the electric motor, including also the utilization of variable speed drives. WEG can support the shift towards these new high efficiency levels by offering a comprehensive range of products that exceed the IE2 and IE3 criteria.
Additionally, our variable speed drives are perfectly matched to our motors, affording you the most reliable package of motor / drive products in industry.
