IE5 + synchronous motors from NORD DRIVESYSTEMS
According to the German Environment Agency , electric drives in the industry and trade sectors consume nearly two fifths of the total electricity in Germany . Particularly electric drives and the aggregates powered by them therefore have a great and economic energy saving potential . With its highly efficient latest-generation IE5 + motors , system provider NORD DRIVESYSTEMS offers an optimum solution for the significant reduction of energy and resource consumptions .
The compact and highly efficient IE5 + permanent magnet synchronous motors ( PMSM ) from NORD are characterised by a constantly high efficiency of up to 95 % over a wide torque range and thus also achieve optimum energy consumption performance in partial load and partial speed ranges . “ That means that the efficiencies of our IE5 + motors clearly exceed those of the highest defined efficiency class
IE5 ”, says Jörg Niermann , Marketing Manager at NORD DRIVESYSTEMS . This significantly reduces the application ’ s energy requirements and CO2e emissions . Particularly for large systems with long operating times of the electric drives – for example in intralogistics with many installed drives – this makes a considerable difference . “ Our IE5 + motor technology , however , is far more than just energy efficiency ”, Niermann adds . “ We rather think of it as a holistic concept that goes beyond the mere consideration of efficiency .”
Material efficiency as a sustainability factor
The compact IE5 + permanent magnet synchronous motors from NORD also convince with their innovative design and require a comparatively small quantity of material . NORD designed the IE5 + motor as an 8-pole synchronous motor in an IPM design . This reduces the size of the motor ’ s active components , which not only results in material savings in the sheet metal package but also with the magnets .
With 8-pole synchronous motors , the stator can also be manufactured with the so-called single-tooth windings . As a result , valuable material such as copper is only used where it is actually productive ; inefficient use in the winding head is reduced . “ Our IE5 + synchronous motor combines energy efficiency with material efficiency and thus scores twice in terms of sustainability ”, Niermann highlights . “ This is also valid for our DuoDrive , which integrates the IE5 + motor with a single-stage helical gear unit into one housing .”
NORD as a system provider
With regard to the energy savings potential , the entire drive system including electric motor , gear unit and drive electronics must be taken into account . The highly efficient IE5 + motors can be combined with different components from the NORD modular system . This creates optimally matched and tailored system solutions from a single source . This allows to increase the total efficiency of machines and systems , and to reduce the Total Costs of Ownership ( TCO ). With the NORD ECO service , the drive experts from NORD also offer an effective tool to reveal savings potential in a system and to minimise the companies ’ carbon footprint . “ Finally , we want to enable the user to make the best possible use of the advantages of our drive systems ”, Niermann summarises . “ To make this work , we assist our customers from the design phase up to commissioning .”
