Who makes standards? WSC World Standards Cooperation

1. ISO International Organization for Standardization

2. IEC International Electrotechnical Commission

3. ITU International Telecommunication Union

Formal standard: a specification that has been approved by a standards

setting organization. De iure standard: a standard mandated by legal requirements or refers

generally to any formal standard. De facto standard: a specification (or protocol or technology) that has

achieved widespread use and acceptance often without being approved by any standards organization (or receiving such approval only after it already has achieved widespread use).


Why standards? Barriers to Trade (WTO) Many products today are traded globally

In every country: Different performance requirements Different tests necessary Different certificates required Different efficiency classification schemes


What is the status of a standard?

A RECOMMENDATION by an NGO

BINDING for its members (i.e. National Committees)

VOLUNTARY for an industrial user

Only when INCLUDED IN A NATIONAL LAW it becomes mandatory

1 SCOPE

Included This part of IEC 60034 specifies efficiency classes for single-speed electric motors that are rated according to IEC 60034-1 or IEC 60079-0, are rated for operation on a sinusoidal voltage supply and: have a rated power PN from 0,12 kW to 1000 kW; have a rated voltage UN above 50 V up to 1 kV; have 2, 4, 6 or 8 poles; are capable of continuous operation at their rated power with a

temperature rise within the specified insulation temperature class; are marked with any ambient temperature within the range of 20 C

to + 60 C; are marked with an altitude up to 4 000 m above sea level. This standard establishes a set of limit efficiency values based on frequency, number of poles and motor power. No distinction is made between motor technologies, supply voltage or motors with increased insulation designed specifically for converter operation even though these motor technologies may not all be capable of reaching the higher efficiency classes (see Table 1). This makes different motor technologies fully comparable with respect to their energy efficiency potential. Motors with flanges, feet and/or shafts with mechanical dimensions

different from IEC 60072-1 are covered by this standard. Geared motors are covered by this standard including those

incorporating non-standard shafts and flanges.

Excluded The efficiency of power-drive systems is not covered by this

standard. In particular, motor losses due to harmonic content of the supply voltage, losses in cables, filters and frequency-converters, are not covered.

Excluded are: Single-speed motors with 10 or more poles or multi-speed motors; Motors with mechanical commutators (such as DC-motors); Motors completely integrated into a machine (for example pump, fan

and compressor) that can not be practically tested separately from the machine even with provision of a temporary end-shield and drive-end bearing; This means the motor must: a) share common components (apart from connectors such as bolts) with the driven unit (for example, a shaft or housing) and; b) not be designed in such a way as to enable the motor to be separated from the driven unit as an entire motor that can operate independently of the driven unit. That is, for a motor to be excluded from this standard, the process of separation must render the motor inoperative

Motors with integrated frequency-converters (compact drives) when the motor cannot be tested separately from the converter; Energy-efficiency classification of compact drives must be based on the complete product (PDS = Power-Drive System) and will be defined in a separate standard.

Submersible motors specifically designed to operate wholly immersed in a liquid;

Smoke extraction motors with a temperature class above 400 C.

5 Certification The IECEE GMEE Program will deliver the following advantages: To give a major contribution to reducing the global energy

consumption Provide the tools for Developing Countries to support the growth of

efficient electric motor products To make available to Developing Countries adoption of the IECEE

GMEE Program instead of spending the resources to establish their own Energy Efficiency Programs

Support the Electric Motor Manufacturers and Suppliers to consistently access the Global Market

To avoid the potential confusion and duplication of testing and verification of electric motor efficiency

To address the various regulations while waiting a more general harmonization of the Energy Efficiency Requirements

The way forward 1. IEC ACEE* will discuss the topic of a

standard format for IEC standards 2. Other IEC TCs are invited to also prepare

efficiency classes 3. Start with motor systems 4. IECEE gains experience on certification
