Introduction
General information regarding efficiency in accordance with International Efficiency
Efficiency classes and efficiencies according to IEC 60034-30-1
■
Overview
(continued)
Background information
Comprehensive laws have been introduced in the European
Union with the objective of reducing energy consumption and
therefore CO
2
emissions. EU Directive 640/2009 concerns the
energy consumption or efficiency of induction motors in the
industrial environment. This Directive is now in force in every
country of the European economic area.

legal requirements, visit:

Exceptions to the EU Directive
7
Motors that are designed to be operated totally submerged in
a liquid;
7
Motors fully integrated into a product (e.g. a gear unit, pump,
fan or compressor) whose energy efficiency cannot be
measured independently of the product;
7
Motors that are specially designed for operation under the
following conditions:
- At altitudes greater than 4000 meters above sea level;
- At ambient temperatures above 60 °C;
- At maximum operating temperatures above 400 °C;
- At ambient temperatures below -30 °C
(any motor);
- With cooling liquid temperatures at the product intake of
below 0 °C, below -15 °C for water-cooled motors or above
32 °C;
- In hazardous areas in the context of Directive 2014/34/EU
of the European Parliament and Council;
7
Brake motors
The following motors are not involved:
•
8-pole motors
•
Pole-changing motors
•
Synchronous motors
•
Single-phase motors
•
Motors specially developed for converter operation in
accordance with IEC 60034-25
The following changes will come into effect on the dates
below:
Since January 1, 2015:
Compliance with the legally required minimum efficiency class
IE3 for power ratings from 7.5 to 375 kW or, as an alternative,
IE2 motor plus frequency converter
Changes in accordance with EU Motor Regulation 640/2009
All converter compatible low-voltage motors with a power rating
of between 7.5 and 375 kW and efficiency IE2 must be labeled
as follows with effect from January 1, 2015:
This obligation applies only within the European Economic Area.
Correct application is the sole responsibility of the customer.
Beginning January 1, 2017:
Compliance with the legally required minimum efficiency class
IE3 for power ratings from 0.75 to 375 kW or, as an alternative,
IE2 motor plus frequency converter
Note:
Different minimum efficiency class requirements apply in China,
Korea and Australia. Other countries will be available soon.
