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 latest-generation IE5+ motors, system provider NORD Drivesystems offers a solution to significantly reduce the consumption of energy and resources.

The IE5+ permanent magnet synchronous motors (PMSM) from NORD are characterised by a 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. 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.

The motors also feature an 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.

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 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.
