NORD DRIVESYSTEMS has extended its SK 200E family of decentralized drive solutions with a new size 4 inverter with a rated power output from 11 to 22 kW.
Despite the introduction of energy efficiency classes IE2, IE3 etc. and the subsequent information that is now available, finding the most resource-efficient drive solution is not easy. A simple catalog based choice will often miss out on potential savings and therefore motors should be carefully selected according to the actual load profile of the application. To avoid inefficient drive specifications, NORD Drivesystems concentrates on power reserves which are derived from various sources. Firstly, the power a motor can generate in compliance with its temperature class is higher than the rated output as given in the catalog and on the motor type plate. Secondly, performance classes rise gradually; for a 3.7 kW output, for instance, it takes a 4 kW motor. Many customers will even select the next motor in size. This kind of “bigger is better” approach is anything but efficient.
In recent years, the German drive technology manufacturer NORD Drivesystems has been very active in the steel industry in China and India. NORD has supplied 2,500 geared motors to the Shanghai Baosteel Group Corporation for a heavy plate mill in Pudong which produces, amongst others, sheets for the ship building industry.
The IECS Company, specializing in the manufacture, assembly and maintenance of quarry and sand pits equipments has chosen NORD gearmotors to power the new aggregates production unit of the Pradier Group. The quality of service, especially in terms of reactivity, and the performance of IE2 motors have made the difference.
Long relegated to mere tech demonstrations and R&D facilities, solar thermal installations built around a central tower are now making the leap to full-scale production sites. Leading the way is Gemasolar in the south of Spain. In order to ensure precise and reliable operation of the plant’s mobile heliostats that focus the sunlight, the vast array comprising 2,650 mirrors is equipped with 5,300 robust geared motors supplied by NORD Drivesystems.
