10.08.2023 • Bruchsal, Düsseldorf, interpack 2023, 03.05.2023 • Drive solutions with DR2C.. synchronous motors from SEW-EURODRIVE comply with the highest efficiency class IE5 for adjustable-speed electric motors. This makes them yet another sustainable and particularly energy-saving motor variant. In spring 2023, they were voted "Product of the Year".

The DR2C.. motor series from SEW-EURODRIVE has been honored with the "Product of the Year" award. In the readers' vote held by the journal Industrial Production, the series claimed 1st place in the Drive Technology and Automation category. In another reader competition by the Computer & Automation magazine, this synchronous motor was also voted into 1st place in the Drive Technology category.

DR2C.. motors comply with the highest efficiency class IE5 defined by the standards for adjustable-speed electric motors. They are designed for exclusive inverter operation. Thanks to their design as synchronous motors, their rotational speeds are not load-dependent. This allows you to design interlinked system parts without any force in the transition. Another key advantage of the synchronous motor technology is the virtually loss-free rotor and the resulting low thermal load, which lead to an improvement in the service life. Combined with efficient gear units and intelligent frequency inverters from the MOVI-C® modular automation system from SEW-EURODRIVE, it is possible to create energy-optimized drive solutions.

The size reduction of these motors, which is often possible compared to the classic IE3 line motor, facilitates their design. The DR2C.. motors have been available since spring 2023 with power ratings of up to 3 kW. They achieve efficiencies of up to 91%. Over the course of the year, the portfolio will be expanded to include further motor sizes and higher power ratings of up to 11 kW, with efficiencies of up to 94.5%.

In module 1 with cross-sectional technologies – including drives, pumps, fans, compressed air generators, etc. – the Federal Office for Economic Affairs and Export Control (BAFA) promotes the use of IE5 motors for operation on a frequency inverter.
