Im Rahmen des vom Bundesministerium für Wirtschaft und Energie (BMWi) geförderten Projekts „ETA-Fabrik“ am Institut für Produktionsmanagement, Technologie und Werkzeugmaschinen (PTW) der Technischen Universität Darmstadt konnte die Energieeffizienz von Motorspindeln als Hauptenergieverbraucher von Werkzeugmaschinen durch Einsatz der Synchronreluktanztechnologie gesteigert werden. In der Konsequenz ergeben sich weitere Energieeinsparpotenziale und produktionstechnische Vorteile durch eine gesamtenergetische Betrachtung der Werkzeugmaschine mit Kühlsystem und intelligentem Spindelthermomanagement.   As part of the ‘ETA-Fabrik’ project funded by the BMWi, the Institute of Production Management, Technology and Machine Tools (PTW) of the TU Darmstadt has used synchronous reluctance drives to increase the energy efficiency of motor spindles as main energy consumers of machine tools. Subsequently, new opportunities for energy savings and advantages for the manufacturing process arise by taking a holistic view on machine tools including the cooling system, proposing an intelligent spindle thermal management.

The Cost

The paper compares the economic effect of using capacitors in fixed speed drives of a pumping station when using energy-efficient motors of various types. Induction motors of IE2 and IE3 energy efficiency classes, a direct-on-line synchronous motor with a permanent magnet in the rotor, and a direct-on-line synchronous reluctance motor are considered. The comparison takes into account not only the efficiency of the motors, but also their power factor, on which the losses in the cable and transformer depend. The possibility of using static capacitors to compensate for the reactive power of motors and reduce the losses is also considered. The feasibility analysis takes into account that the motors have different initial costs. The cost of capacitors is also taken into consideration. The analysis shows that the use of static capacitors can have a significant impact on the comparison between different motors in this application. Without considering capacitors, the permanent magnet motor has the shortest payback period, otherwise the synchronous reluctance motor has the shortest payback period.
