Drive technology seeks to optimise energy requirements Dwindling resources, spiralling energy costs, increasingly stringent international regulations, and the trend towards cutting carbon emissions has meant that technology leaders such as SEW-EURODRIVE are focusing more and more on optimising energy requirements.

company’s newly introduced IE3- compliant DRNmotor range. In termsof someof the latest prod- uct developments, the MOVIGEAR ® mechatronic drive system, which combines an energy-efficient gear unit, motor and frequency inverter, has received theTÜVSÜDEnergy- Efficient Plant Technology certificate. The effiDRIVE ® energy-sav- ing solution allows customers to realise measurable success in this regard by optimising energy con- sumption in order to reduce costs.

I n order to realise savings in energy costs, SEW-EURODRIVE has been focusing on how to optimise energy requirements. Numerous system components have to be analysed to realise the full energy-saving potential of drive technology applications. It is important to bear in mind that energy-effi- cient solutions that save thedesiredenergy in one application could lead to a higher overall energy consumption in another. “A ‘one-fits- all’ approach is not well suited for this type of exercise, which means that the customer- focused, total solutions approach offered by SEW-EURODRIVE has emerged as the best way to effect results in optimal savings,” says national sales manager, Norman Maleka. “A comprehensive range of resources is available to plant manufacturers and opera- tors to help identify energy-saving opportu- nities in the field of electric drive technology. These include an energy consulting service, basedonamodular andcustomisable concept in terms of optimisation and technical imple- mentation,” Maleka continues. An energy-saving calculator is offered as a free software tool, which allows custom- ers to compare the energy consumption of standard and energy-efficient motors. The payback period of the investment required can then also be calculated, with the results downloadable in PDF format. In addition, the SEWWorkbenchprojectplanningtoolreveals the overall energy consumption for a specific application and its configured drive train in the form of an energy analysis report. Global energy-efficiency regulations can be perused via a smartphone app, where carbon dioxide and energy-saving potential can be calculated, in addition to full techni- cal details of the changeover effects of an energy-efficient motor, such as one from the
