SEW-Eurodrive’s IE3-compliant DRN series of asynchronous motors has set a new benchmark for energy efficiency in the local electric motor industry. Stricter international regulations have meant that all two-, four- and six-pole asynchronous motors with a power rating of 7,5 to 375 kW must meet the requirements of energy efficiency class IE3 in the European Union (EU). While South Africa does not face the same regulatory pressure as the EU, SEW-Eurodrive has decided to raise the benchmark locally by launching the new DRN series as its standard range of electric motors. “We not only supply the local market, but have to take our export obligations into account as well,” explains national sales manager, Norman Maleka.
SEW-Eurodrive offers the DRN series as a complete range. “It sets the standard. A customer who buys a gearbox or drive from us will automatically have an IE3-compliant motor,” he adds. “The DRN series is downward compatible with our previous motors, regardless of the energy class. It fits right onto our gearboxes, for example. Another feature is a global stator, which boosts both parts availability and stockholding.
Maleka points out that the total cost of ownership of the equipment is reduced significantly over the long term. “Not only do we inform our customers about these benefits, but we also advise on application requirements. Our aim is to offer a total solution, as opposed to simply being a component supplier,” he concludes.
