These IE3 motors have reduced users' energy costs by more than €2.3 billion. The three millionth motor was delivered to Masa GmbH, which specializes in machinery for the building materials industry. Masa uses the bevel gear motors for the manufacture of concrete products. SEW-Eurodrive has been successfully selling the energy-saving motors of the DRN.. series in the Premium Efficiency Class (IE3) to equipment manufacturers and end users since 2015.
