Economical Motors

Responding to the increasingly demanding energy saving regulations for motors across many markets, NORD DRIVESYSTEMS now provides IE4 systems from 0.55 to 7.5 kW in motor sizes from 80 to 100. IE3 motors up to size 180 are also available. In addition to standard IE2 models, which have been available worldwide for some time now, IE2 ATEX versions in size 80 to 180 are offered. The company has also made various additions to its gearbox offerings, which now cover torques from 25 to 242 kNm. In this series, a standard housing per frame size spans the entire transmission range. This highly flexible modular concept provides countless options for straightforward and fast configuration for individually required models. Another key product from the company, the new two-stage helical bevel gear units in open or closed washdown designs can be easily cleaned. Both robust and very lightweight, these aluminum gearboxes are available in five frame sizes with torques from 90 to 660 Nm. Following the same principle, the new two gearbox SMI series have highly resistant and very smooth surfaces. These worm gear units are optimally suited for applications with demanding hygiene requirements. The company’s new treatment for aluminum surfaces provides high corrosion-protection that is equal to that of stainless steel. In addition, SK 200E frequency inverters with output ratings up to 22 kW are available for distributed installation. SK 500E control cabinet inverters reach up to 90 kW with models for up to 160 kW under way. On the other hand, the intelligent SK 540E inverter supports the IEC 61131 standard for programming of drive-related functions. The SK 200E and SK 500E series inverters employ fast ISD current control technology which ensures constant speed under changing loads and provides very high torques during start-up. Due to a wide choice of optional functions, users can select the ideal combination for highly precise applications that are realized at very competitive cost. Users are able to implement servo-like performance by combining advanced features with encoder feedback for speed and position control as fully preconfigured units from one source. Currently, the company is preparing solutions for encoderless control of permanent magnet synchronous motors with very high drive efficiency.
