IEA 4E Electric Motor Systems

On Wednesday 21 May 2025 Frank Hartkamp passed away. He was only 61. Frank has been the Dutch representative in EMSA (the Electric Motor Systems Platform in the IEA Technology Collaboration Programme 4E Energy Efficient End-use Equipment) from the start in 2009 and he has acted as Vice-Chair of EMSA since 2019. Frank always worked with a keen eye on finding practical connections and solutions in cooperation with people and institutions that could bring the matter further. In this case the matter was energy savings – in electric motor systems, ICT and more. He combined his work with humor, wit, music, compassion and more. May he rest in peace.

How to set Minimum Energy Performance Standards for electric motors, Variable Speed Drives, pumps, fans and air compressors? U4E released its updated Motor Policy Guide and Model Regulations to support policy makers in developing countries and emerging economies in transitioning to energy-efficient motor systems. The Motor Policy Guide presents the Integrated Policy Approach, including standards and regulations, Monitoring, Verification and Enforcement, financial delivery mechanisms, as well as environmental sustainability and health policies. A differentiated policy approach is applied, ensuring that both new equipment and the installed base are addressed. The Model Regulation Guidelines offer a template framework for developing regulations that drive efficiency improvements. For electric motor requirements, both advanced and bridging levels are proposed, allowing economies a variety of options to consider based on their individual situation.

How to overcome the barriers to the adoption of Wide Bandgap Industrial Variable Speed Drives? The adoption of Wide Bandgap (WBG) semiconductors in industrial Variable Speed Drives (VSDs) presents multiple advantages, including improved efficiency, reduced cooling requirements and smaller form factors. Despite their numerous advantages, the adoption of WBG industrial VSDs faces several challenges. Ongoing research and development efforts continue to address these challenges, aiming to reduce cost, improve reliability and expand the support infrastructure for WBG technology. By documenting these improvements, EMSA in cooperation with PECTA will develop a White Book by 2028, aiming to address the barriers to the adoption of Silicon Carbide (SiC) and Gallium Nitride (GaN) for industrial VSDs. A WBG Research Roadmap has been developed (see figure), detailing the aspects to be considered in ongoing and planned research activities, according to different research topics.

Advancing industrial inverters: the research roadmap for Wide Bandgap Power Semiconductors Andrea Vezzini will present during a webinar at the Motors Academy on 21 November 2024 the development of a comprehensive “White Book on Wide Bandgap Semiconductor-Based Industrial Inverters.” As part of the IEA 4E EMSA Electric Motor Systems Platform, Switzerland is leading this project in close cooperation with the IEA 4E PECTA Power Electronic Conversion Platform. The planned White Book will delve deep into the use of wide bandgap semiconductors in industrial drives, such as SiC (Silicon Carbide) and GaN (Gallium Nitride). It will offer an in-depth exploration of the theoretical foundations, technological advancements, and practical applications of Wide Bandgap semiconductors, specifically within the context of industrial automation. It will as well address the opportunities and challenges these technologies present, providing a forward-looking perspective on their future impact. For the upcoming White Book, an in-depth roadmap has been developed, showing the relevant challenges and the issues to be elaborated, in particular research activities for a well-founded knowledge-base. The targeted White Book is designed to be an invaluable tool for a broad audience, including professionals and engineers, manufacturers and suppliers, policymakers, regulatory bodies, standardisation organisations, and industry consortia, involved in power electronics and industrial automation. After the presentation, you will have the opportunity to interact with the speaker during the Q&A session.

On Tuesday 5 November 2024, EMSA presented during a Motors Academy webinar an overview of relevant international standards for electric motor systems as well as the worldwide status of Minimum Energy Performance Standards (MEPS) for electric motors, Variable Speed Drives, pumps, fans and air compressors. The presentation also discussed recent developments and future aspects of MEPS and other policies. Key takeaways: - Standards serve as building blocks for regulations. - Coordination & alignment of standards dedicated to parts of the motor system is happening under the umbrella of the ISO/IEC JAG 22. - MEPS for motors evolve and expand in scope, stringency and coverage worldwide. Today 55 countries have MEPS in place, 46 of which at IE3 level. While there are still blank spots on the map, countries with MEPS represent around 80% of global electricity use by motors. - MEPS for pumps, fans, air compressors are in place in a few main economic regions; they evolve from regulating the component to regulating the complete unit (motor+drive+application). - MEPS covering induction motors are reaching a point of diminishing returns. The important question for the future is, how to harvest system savings, thus which metrics to use, where to draw the system boundary, weighing benefits and costs of new/additional requirements. - While MEPS address newly sold equipment, other supporting policies are needed to address the installed base, such as awareness raising, capacity building, financial incentives.   See webinar video & presentation: https://lnkd.in/g-2YyivC The Motors Academy webinar series aims to provide valuable insights and updates on the policy, market, and technological aspects of industrial motors and e-mobility drivetrains.
