Nord Drivesystems has implemented a three point concept for its energy-saving motors which fulfill the globally applicable requirements of the new IEC standard 60034–30. Compliance with the IE2 efficiency class is achieved firstly by the use of more active material, secondly by choosing higher quality sheet metal with less losses, and thirdly with increased copper filling factors in combination with a simultaneous reduction in the size of the winding heads through an optimised production process. IE2 motors have been available for several months. They offer various advantages over previous models, including improved efficiency, higher start-up and breakdown torques, decreased slip, and less waste heat and better thermal performance. Compared to their direct predecessor models, IE2-type motors thus offer an increased service life and help save operating costs. If required, the operating range, which has been shifted upwards towards a better efficiency, can be used to continuously operate the motors at a 150 % performance factor. Alternatively, users can choose a smaller motor type for many applications.
