  1. LOT 30ECO-DESIGN OF ELECTRIC MOTORSFinal Meeting Anibal De Almeida ISR – University of Coimbra Brussels, February 10, 2014 ISR – University of Coimbra

  2. Agenda ISR – University of Coimbra

  3. Methodology Outline ISR – University of Coimbra

  4. Timing of Tasks ISR – University of Coimbra

  5. Task 4 This section entails a general technical analysis of current products, as defined in section 1, and provides general inputs for the definition of the BaseCases ISR – University of Coimbra

  6. BaseCases – Small Motors For Small motors in the power range of 120 W up to 750 W, two BaseCases will be considered: • BaseCase 1 – 1-Phase Induction Motor (IM), 370 W, IE1 • BaseCase 2 – 3-Phase Induction Motor (IM), 370 W, IE1 ISR – University of Coimbra

  7. BaseCases – Medium Motors Medium motors in the power range from 0.75 kW up to 375 kW: • BaseCase 3 –1-Phase IM, 1,1 kW – IE2 • BaseCase 4 – 3-Phase IM, 1,1 kW – IE2 • BaseCase 5 – 3-Phase IM, 11 kW – IE2 • BaseCase 6 – 3-Phase IM, 110 kW – IE2 ISR – University of Coimbra

  8. BaseCases – Large Motors Large motors in the power range above 375 kW, up to 1000 kW: BaseCase 7 – 3-Phase IM, 750 kW LV, IE2 BaseCase 8 – 3-Phase IM 750 kW MV (6600V), IE2 MV motor efficiency is not defined in the IEC 60034-30-1 standard. For the purpose of the study, it is considered that MV motors have the same efficiency level as LV motors for the same power. ISR – University of Coimbra

  9. BaseCases – Submersible Pumps motors Two additional BaseCasesare also considered for submersible motors. Submersible Motors are a separable part of the Multistage submersible borehole pumps considered in Lot29. The analysis of these is within LOT30 so that the analysis is done on the same basis as other motors, but the results of this analysis will be highly relevant to LOT29. ISR – University of Coimbra

  10. BaseCases - VSDs For the analysis of Variable Speed Drives (VSDs) one additional BaseCase will be considered for each of the above motor powers, when coupled with a VSD. ISR – University of Coimbra

  11. BaseCases – Soft-Starters For the analysis of Soft-Starters three BaseCases were considered for 1.1 kW, 11 kW and 110 kW motor, each coupled to a Soft-Starter. ISR – University of Coimbra

  13. BoM – Medium Motors (IE2) Source: CEMEP ISR – University of Coimbra

  14. BoM – Large Motors (750 kW IE2) Source: CEMEP ISR – University of Coimbra

  15. BoM - VSDs Source: LOT 11 ISR – University of Coimbra

  16. BoM – Soft - Starters Source: CAPIEL ISR – University of Coimbra

  17. Bill-of-Materials (Error) Because of the limitations in materials available in the EcoReport tool, the error in this approximation is far greater than that of small differences in the material composition of the product. ISR – University of Coimbra

  18. Distribution Phase Average Volume of Packaged Product Source: CEMEP and CAPIEL ISR – University of Coimbra

  19. Use Phase – Motors (IEC 60034-30) BasecaseFull-Load Efficiency – Small motors (0,37 kW) IE1 BasecaseFull-Load Efficiency – Medium motors IE2 Basecase Full-Load Efficiency – Large motors (750 kW) IE2 ISR – University of Coimbra

  20. Use Phase - Motors Motor Efficiency vs. Load IEC 60034-31 ISR – University of Coimbra

  21. Use Phase - VSDs The full load efficiency of a VSD is typically around 97-98%, 11 kW VSD Source: ISR-Univ Coimbra ISR – University of Coimbra

  22. Additional harmonic lossesMotors + VSD IEC/TS 60034-2-3 states the harmonic losses will contribute to a higher relative losses value (15% to 25%) in the motor. A constant 20% increase of losses in the motor are considered ISR – University of Coimbra

  23. Use Phase - VSDs Basecase Efficiency – VSDs Source: DoE and ISR-UC ISR – University of Coimbra

  24. Use Phase – Soft Starters Source: CAPIEL ISR – University of Coimbra
