This analysis shows the relevance of high energy performance standards for electric motors. Not only they save energy, but also materials, when considering the net balance at system level.

Last week during the International Copper Association Europe's #MotorsAcademy, I had the chance to talk about key success factors of a financial incentive programme for electric motor systems. Key takeaways: 1. According to our evaluation, the Swiss competitive tenders have come close to reaping the savings potential available within the framework of the programme for electric motor systems to industrial end-users. Due to the design of the programme (cost-effectiveness of measures being the main criteria for programme funding) and different programme requirements concerning budget and share of expenditures/subsidy, these were more the low hanging fruits. 2. There are different key factors influencing programme success: a) Contact to programme participants. In Switzerland, this happened through different channels, e.g. technical partners (installers, manufacturers, vendors, service companies), an existing network of technical consultants, or an existing network of industrial clients. b) Awareness within target group. Programmes need time for their rollout, therefore programme duration also plays a role in success. Longer time horizons can be favourable for upfront investments, such as programme communication. c) Easy participation. Keep the administrative burden of participation as low as possible, including application and monitoring of implemented measures. Programme participants valued a simple and easy-to-understand subsidy scheme, e.g. x% of investment cost, that can be determined and communicated clearly. d) Tangible subsidy. Programme participants found a subsidy of 20% - 30% of the investment cost "high enough". This significantly improves return on investment and facilitates the willingness to accept the administrative burden of participation. e) Qualification of involved consultants. This is an absolute must to be able to spot potentials for improvement and implement these. The comprehensive analysis of the EU-MORE project of policies for motor replacement across Europe has shown, that energy audits often fail to identify motor optimisation measures. 3. Our study team recommended the following building blocks for a successful programme: #1 Subsidy programme for electric motor systems #2 Utility programme #3 Innovation programme #4 Accompanying measures (training, communication, tools). We believe that #4 is a must, no matter whether just one or all other building blocks are implemented. 4. Switzerland decided to go ahead with energy efficiency obligations for electricity suppliers from 2025. Curious to see how this unfolds!

💡 An IE4 induction motor has a lower life cycle impact than an IE3 motor 💡 When looking at entire electrical system, taking not only the motor itself into account, but also the generation capacity associated with the energy losses, the life cycle impact of an IE4 motor is lower than the impact of its IE3 equivalent. This was demonstrated in a design exercise and #lifecycleassessment (LCA) by the International Copper Association Europe and University of Coimbra (Universidade de Coimbra) INSTITUTO DE SISTEMAS E ROBÓTICA - ISR The calculation was made for an 11 kW motor with 1,750 h/y full load equivalent. For the generation capacity, the electricity mix as predicted by the European Commission #GreenDeal Impact Assessment was considered (https://lnkd.in/gA8d6jHD), and the #lifecycle impact for each type of generation capacity was taken from the UNECE Sustainable Energy Integrated Life-cycle Assessment of Electricity Sources (https://lnkd.in/gnfjp_B5). The #LCA results demonstrate that the IE4 motor is favourable for all the LCA impact categories, including climate change and fossil fuel use, and both for an aluminium rotor motor and for a #copper rotor motor. The results of this research were presented at CWIEME Events (Coil Winding, Insulation, & Electrical Manufacturing Exhibition) in May 2024 and at eemods'24 in September 2024. #electricmotor Ladji Tikana Luigi Ulli Daniel Eberli Alexandra da Fonte Martins Rita Werle Andrea Vezzini

Don't miss this fantastic tool for motor design: MST. Yesterday we had a great webinar. Check recording and slides now available: https://lnkd.in/dnQRejCV What we have learnt: 1️⃣ The tool models the entire #motorsystem, from power supply to application, calculating all partial efficiencies and total system efficiency from a single known duty point. 2️⃣ The tool dynamically calculates changes in #speed, #load, or components, providing instant results. 3️⃣ Standardised models are included for #pumps, #fans, hydraulic pumps, air, and #cooling #compressors (including from Ghent University, IEC, and AMCA). 4️⃣ The Motor Systems Tool (MST) allows users to simulate annual #costs, compare energy demands before and after system changes, and evaluate systems under #EU #Ecodesign standards. 5️⃣ Regular updates align the MST with new legislation. Upcoming updates will incorporate the EU Ecodesign regulation 2024/1834 for fans (adopted 3 July 2024) and expected updates for water pumps by mid-2025. 6️⃣ Developed on LabVIEW and running on Microsoft Windows, the tool features a visual dashboard for easy #simulations. Results and settings can be exported as an HTML page. 7️⃣ For Motor/Drive unit selection, #induction, #permanentmagnet and #synchronous #reluctance #motors are available. Users can manually input nameplate values, with a built-in validation to prevent unrealistic entries. 8️⃣ Real-life examples demonstrated: 👉 Pump application: With minimal input, the tool provides a complete analysis of the entire pump system. 👉 Fan application interpolation: Efficiency at any duty point is extrapolated from 12 representative duty points based on detailed fan curves, allowing full system calculations.

*** Does it make sense to further tighten #energyefficiency requirements for industrial motors in the #EU #Ecodesign regulation? *** To respond to this question under a holistic perspective we have carried out an analysis of #IE3 vs #IE4 motors in the 0.75 - 75 kW segment: ⚡️ #energysavings: EU-27 potential is estimated 2 TWh/year. 💰 #financialsavings: Total cost of ownership is significantly reduced, with a short payback period. 🧱️ #resourceefficiency: IE4 motors use between 14 kg and 30 kg more of metals. However, the avoided energy losses save 55 kg of metals in generation infrastructure. Higher #MEPS save resources! 👣 #lifecycleassessment: All LCA impact categories improve with IE4.
