Efficient motor systems

Efficient electric motor systems

Forum for exchange

The "Technology Collaboration Program on Efficient Electrical End-use Equipment" offers the participating countries and other potential partners from industry a forum for exchanging information and experience. It also aims to support the coordination of international concepts, initiatives and programs to strengthen energy-efficient technologies.

The Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology (BMK) commissioned the Austrian Energy Agency to manage the "Annex Electric Motor Systems" project of the 4E TCP via the Österreichische Forschungsförderungsgesellschaft mbH. Other members of the Annex are Australia / Denmark / European Commission / Netherlands / New Zealand / Austria / Sweden / Switzerland / USA.

"Annex Motor Systems"

The main objective of the Motor Annex project is to support the installation of energy-efficient electric motors and motor systems such as pumps, fans and compressors. This is to be achieved by:

Collection, bundling and promotion of activities on efficient motor systems in Austria
International networking of the relevant players
Observation and assessment of new developments in the industry (digitalization)
Fundamental market preparation and development impulses
Information of developers and manufacturers, planners and users and political decision-makers on efficiency criteria for electric motor systems via databases, guidelines and direct information
Strengthening Austria as a development and research location by strengthening sustainable technologies, both on the supply and demand side

Instruments for the installation of energy-efficient electric motors and motor systems

In detail, the following areas are covered by the annex:

Policy
The Electric Motor Systems Annex (EMSA) presents international experiences of successful policy instruments for increasing efficiency in motor systems. The Policy Guidelines for Electric Motor Systems were published at the end of 2014. This task was led by the Austrian Energy Agency.
Audits of Electric Motor Systems
Until 2017, Austria's participation included in particular the Energy Audits for Motorsystems task lead for the development of recommendations for the implementation of standard-compliant energy audits in motor systems and published the "Energy Audit Guide for Electric Motor Systems-Recommended Steps"

in 2018.

Monitoring and Assessing New Industrial Developments
The Austrian Energy Agency has been leading this task since 2017, focusing on the impact of Industry 4.0 on electric motors. The first report in 2019 includes:
- An overview of the most important elements of Industry 4.0 and their potential impact on energy consumption,
- A range of application examples and products for Industry 4.0 in different motor systems
- Options for energy management in the layers of the automation pyramid
- Compilation of the requirements for electric motors associated with Industry 4.0
- Furthermore, a report on the classification of digital technologies for increasing energy efficiency (2022)
  - abstract
- In addition, a survey on the use of digital technologies, the advantages and disadvantages of digital technologies and the savings potential (2021).
  - Summary
- Further results such as the mapping of political programs and two use cases were published in the final report on the first project phase 2022.
International Standards
EMSA is committed to globally harmonized and robust technical standards and norms for the classification and testing of motors and frequency converters through participation in standards committees.
Testing Centers
EMSA develops guidelines for testing motors (IEC 60034-2-1 test method)

Technical Guide
Motor guide with basic options for saving energy in motor systems and tips for implementation in practice.

Tool
The Motor Systems Tool developed as part of the Electric Motor System Annex is intended to support energy engineers, mechanical engineers, component suppliers and energy consultants in the design and optimization of motor systems. To this end, it calculates the overall efficiency of the entire system, depending on the selected components and load.
