Questions concerning the web application

The manufacturers are responsible for distributing their own data. Via Manufacturer Data you can find an overview of manufacturers who either send the data via email or provide the data on their homepage to download. 
As a manufacturer you can enter the losses of your components in the respective excel templates, which you can download here. You can either offer the filled out excel sheets for downloading on your homepage or send them via email upon request.
In the third step of the calculation process, it is possible to enter an additional operating point. The losses in this point are calculated by interpolation.
The method described in the standard in annex G.2.3 for loss determination by two-dimensional interpolation of losses of neighbouring loss points is used.
For data protection reasons the imported data is only saved for the time of the session. If you want to use the data again later, a repeated import is necessary.
Additionally, the results are not saved in the web application. In order to save your results, you can export your calculation as pdf- or excel-file.

Questions concerning EN 50598

The standard consists of three parts. Part 2 specifies parameters for the evaluation of energy efficiency of motor systems for applications in a power range from 0.12 kW to 1,000 kW. It also includes a suggestion for the approach to characterise the most energy-efficient solution for the so-called extended product (motor system and driven equipment). This standard establishes a method for determining the losses of power drive systems (PDS) as well as complete drive modules (CDM). It defines efficiency classes for PDS (IES classes) and CDM (IE classes) as well as limit values and test methods. Determining the losses of the systems is based on a semi analytical model with which the total efficiency can be characterised based on the motor driven system architecture, the speed/load profile and the operating points over time of the driven equipment.
 
Part 1 of the standard defines the requirements related to the semi analytical models in general in order to work on the extended product approach.
Part 3 of the standard defines the requirements for determining the ecological footprint of drive products.
A PDS is a power drive system. It consists of a motor and a CDM (complete drive module). The CDM contains the variable speed drive including input and output components as well as feed-in unit and accessories. 
The IES classes are defined in relation to a reference PDS. If the losses of a real PDS are in a range of +/-20 per cent of the losses of the reference PDS, it is defined as IES1. Are the losses of the real PDS more than 20 per cent lower than the reference PDS, it can be classified as IES2, are the losses more than 20 per cent higher, a PDS is of class IES0.
The EN 50598-2 defines reference PDS which are based on a 400 V reference CDM and a 4-pole reference motor of efficiency class IE2. For PDS and CDM in the power range from 0.12 to 1,000 kW the reference values can be found in annex A of the standard.
The efficiencies of the motors are stated for 50 Hz and/or 60 Hz mains operation. This is a good way to compare the energy efficiency of line-fed motors from different manufacturers, even though the power losses have to be determined according to the standard in this case also.
 
Controlled drives consist of many individual components. Beside the motor, these are the complete drive module with the variable speed drive and accessories like e.g. input and output components. In the past, the efficiencies of variable speed drives were stated in a very general manner as e.g. ≤97.5 percent. The information was mostly limited to the basic unit, which means the power part without accessories. Stating the power loss in watt was the exception. For cables, it is not common to specify the efficiency.
 
By specifying the power loss in watt consistently the comparability and handling, e.g. the addition of the individual power loss factors is simplified and made clearer.
 
, this approach makes it possible to take a motor into consideration, which generates for example a holding torque at zero speed. The efficiency is always zero in this case, but the power loss can differ. 
EN 50598-2 only considers systems with asynchronous motors to begin with. The basic principles of the standard are independent of technology though. 
Yes. Even though an IE3 motor is used in a PDS, the same reference values apply as for an IE2 motor. It is possible that the PDS can be classed in a higher efficiency class as a result.
Yes. It is still possible and useful to assemble a system from components by different manufacturers. To class the system (IES class) it is necessary to know the individual components though.
The standard IEC 61800-9-2 is in preparation at the moment and is expected to be published in 2016/17. Its content is very similar to EN 50598-2 and it is supposed to replace it. Therefore, the standard is taken from European to international level. 

General questions

IEC 60034-30-1: Rotating electrical machines – Part 30-1: Efficiency classes of line operated AC motors (IE code)

Current: first edition of 6 March 2014

Content: Definition of IE classes IE1 to IE4 for three-phase motors (synchronous / asynchronous) on basis of full-load efficiency. This standard applies to all types of motors designed for line-operation. It also applicable to motors, which can be operated on the mains or with a variable speed drive. These are in general standard asynchronous motors or synchronous motors with starting cage (line-start permanent magnet or line-start synchronous reluctance).
Ecodesign Directive 2009/125/EC: Establishing a framework for the setting of ecodesign requirements for energy-related products (Ecodesign framework directive)

Current: Edition of 21 October 2009, replaces directive 2005/32/EG (EUP) of 6 July 2005

Content: Framework directive without specific technical contents

EU regulation 640/2009 for implementing Directive 2005/32/EG (EUP)

Current: Edition of 22 July 2009

Content: Minimum values for the efficiency are defined for 2-, 4- or 6-pole low-voltage asynchronous motors between 0.75 and 375 kW. Motors with a nominal output power higher than 7.5 KW have to reach IE3 or IE2 together with a variable speed drive. From 1 January 2017 IE3 or IE2+VSD applies to smaller motors also.

In addition, the regulation lists the relevant data (product information), which need to be provided by the manufacturer.
The regulation applies only to motors, which are designed for continuous operation (S1) and comply with the series standard (up to 40°C, 1,000 m above sea level etc.). Explosion-protected motors and Brake motors are excluded also.

EU regulation 4/2014 for amending regulation 640/2009

Current: Edition  of 6 January 2014

Now all motors in a temperature range of -30°C to 60°C (air cooling) as well as altitudes of up to 4,000 m are included. Brake motors are still excluded, even if they are standard motors with a separate added brake.

Additionally, it was clarified that manufacturers only have to stamp only the efficiency in rating mode on the rating plate. All other information has to be included in the product documentation. 
In principle, one has to distinguish between standards and directives.

Standards describe products and methods but they have no legal force. Manufacturers can comply with a standard or not, if the customer accepts it. Often customers or the market demand compliance with particular standards. The manufacturer can confirm this by order confirmation or by stamping the name of the standard on the rating plate. In this case, the terms of the standard have to be met, as it is an assured quality in this case.
Harmonised (that means listed in the official journal of the EU) standards play a particular role. The EU considers them suitable to describe a situation bindingly; when complying with a harmonised standard it is assumed, that the directive or statutory regulation is met.
 
Mandated standards arise from an instruction (mandate) of the European Commission to develop certain European standards. The European Commission therefore is involved in the financing of these standardisation projects. Only after listing in the official journal does a mandated standard become a harmonised standard, which means a higher obligation.
 
EU directives commit the member states of the EU. They have to be adopted in national law in within a period of notice and then have legal force. This applies for example to the regulations 640/2009 and 4/2014 as well as the Ecodesign directive itself.
