1. ENERGY  EFFICIENCY  REQUIREMENTS  FOR  MOTORS  
Energy e fficiency requirements for motors shall apply according to the following timetable:  
(a) from 15 January  2021: 
the energy efficiency of three -phase motors with a rated output equal to or above 
0,75 kW and equal to or below 1  000 kW, with 2, 4 or 6 poles, which are not brake 
motors , increased safety motors, or other explosion -protected motors , shall 
correspond to at least the IE3 efficiency level set out in Table  2 ; 
(b) from 1  July 2022:  
(i) the energy efficiency of three -phase motors with a rated output equal to or  
above 0,12  kW and below 0,75  kW, single -phase motors with a rated output 
equal to or above 0,12  kW and increased safety motors with a rated output 
equal to or above 0,12  kW and equal to or below 1  000 kW shall correspond to 
at least the IE2 efficiency lev el set out in Table  1;  
(ii) the energy efficiency of three -phase motors with a rated output equal to or 
above 0,75  kW and equal to or below 1  000 kW with 2, 4, 6 or 8 poles, that are 
not increased safety motors, shall correspond to at least the IE3 effici ency 
level.  
Energy efficiency for motors, expressed in  International Energy e fficiency classes  (IE), is set 
out in Tables  1, 2 and  3, for different values of the motor rated output power PN. IE classes are  
determined at rated output power (P N), rated volta ge (U N), based on the 50  Hz operation and 
25 °C ambient reference temperature.

MEASUREMENT METHODS  
For the purposes of compliance and verification of compliance with the requirements  of this 
Regulation , measurements and calculations shall be made using harmonised standards the 
reference numbers of which have been published for this purpose in the Official Journal of the 
European Union  or other reliable accurate and reproducible method s which take into account 
the generally recognised state -of-the-art and in line with the following provisions:  
1. FOR MOTORS  
For the purpose of the requirements se t in annex I (1) and (2) for 60  Hz motors, equivalent 
values of the rated output power (P N) and rated voltage (U N) for the 50  Hz operation shall be 
calculated based on  the values applicable at 60  Hz. 
The difference between the output mechanical power and the input electrical power is due to 
losses occurring in the motor. Total losses shall be determi ned using the following methods:  
– Single phase motors: Direct measurement : Input -Output;  
– Three -phase motors: Summa tion of losses: Residual losses.  
2. FOR VARIABLE SPEED DR IVES 
For the determination of the IE class, t he power losses of VSDs shall be determined at 100  % 
rated torque producing current and 90  % rated motor stator frequency according to one of the 
following methods:  
– the input -output method; or  
– the calorimetric method.  
The test  switching frequency shall be 4  kHz until 90  kW (111  kVA) and 2  kHz above.

VERIFICATION PROCEDURE FOR MARKET SURVEILLANCE PURPOSES  
The verification tolerances defined in this Annex relate only to the verification of the 
measured parameters by Member State authorities and shall not be used by the  manufacturer 
or importer as an allowed tolerance to establish the values in the technical documentation or 
in interpreting these values with a view to achieving compliance or to communicate better 
performance by any means.  
When verifying that a product mo del complies with the requirements laid down in this 
Regulation pursuant to Article  3(2) of Directive 2009/125/EC for the requirements referred to 
in this Annex the authorities of the Member States shall apply the following procedure.  
(1) The Member State auth orities shall verify one single unit of the model.  
(2) The model shall be considered to comply with the applicable requirements if:  
(a) the values given in the technical documentati on pursuant to point  2 of 
Annex  IV to Directive 2009/125/EC (declared values) and w here applicable the 
values used to calculate these values are not more favourable for the 
manufacturer or importer than the results of the corresponding measurements 
carried out pursuant to point (g) thereof; and  
(b) the declared values meet any requirements laid down in this Regulation and 
any required  product information published by the manufacturer or importer 
does not contain values that are more favourable for the manufacturer or 
importer than the declared values; and  
(c) when the Member State authorities t est the unit of the model the determined 
values (the values of the relevant parameters as measured in testing and the 
values calculated from these measurements) including the total losses (1 -η) as 
the decisive criterion for the efficiency comply with the r espective verification 
tolerances as set out in Table  7. 
(3) If the results referred to in points  (2)(a) or (2)(b) are not achieved the model and all 
equivalent models shall be considered not to comply with this Regulation.  
(4) If the result referred to in point  (2)(c) is not achieved;  
(a) for models that are produced in quantities of less than five per year the model 
shall be considered not to comply with this Regulation;  
(b) for models that are produced in quantities of five or more per year the Member 
State authorities  shall select three additional units of the same model for 
testing. As an alternative one or more of the three additional units selected may 
be of an equivalent model. The model shall be considered to comply with the 
applicable requirements if for these th ree units the arithmetical mean of the 
determined values including the total losses (1 -η) as decisive criterion for the 
efficiency complies with the respective verification tolerances given in Table  7. 
(5) If the result referred to in point (4)(b) is not achieved the model and all equivalent 
models shall be considered not to comply with this Regulation.  
(6) The Member State authorities shall provide all relevant information to the authorities 
of the other Member States and to the Commission without delay after  a decision is 
taken on the non -compliance of the model according to points  (3) (4)(a) and (5).  
EN 11  EN The Member State authorities shall use the measurement and calculation methods set out in 
Annex  II. 
Given the weight and size limitations for the transportation  of motors and variable speed 
drives with a rated power output of 375 to 1  000 kW Member States authorities may decide to 
undertake the verification procedure at the premises of manufacturers or importers before the 
products are put into service.  
The Membe r State authorities shall only apply the tolerances set out in Table  7 and shall only 
use the procedure described in points  (1) to (6) for the requirements referred to in this Annex. 
No other tolerances such as those set out in harmonised standards or in a ny other 
measurement method shall be applied.  
Table 7 — Verification tolerances  
Parameters  Verification tolerances  
Total losses (1 -η) for motors with a rated 
output equal to or above 0.12  kW and equal 
to or below 150  kW. The determined value  shall not exceed the 
value (1-η) calculated based on the declared η 
by more than 15  %. 
Total losses (1 -η) for motors with a rated 
output of above 150  kW and equal to or 
below 1  000 kW. The determined value  shall not exceed the 
value (1-η) calculated based  on the declared η 
by more than 10  %. 
Total losses for variable speed drives.  The determined value  shall not exceed the 
declared value by more than 5  %.

INDICATIVE BENCHMARKS  
At the time of adoption of this Regulation the best available technology on the market for the 
environmental aspects that were considered significant and are quantifiable is indicated 
below.  
For motors the IE4 level was identified as the best available technology. IE5 motors exist but 
within limited av ailability and not in all power ranges covered by this Regulation and not in 
the form of induction motors.  
For variable speed drives the IE4 level was identified as the best available technology 
assumed to correspond to power losses equal  to or lower than 56,3 % of the IE2 maximum 
power losses although there is not yet an internationally agreed standard that defines the IE4 
level.
