Highest efficiency through application-specific drive configuration: Optimizing drive solutions, tapping power reserves

Highest efficiency through application-specific drive configuration: Optimizing drive solutions, tapping power reserves" style="padding:0px 10px 0px 0px" />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.

Nord Drive’s Contribution in Holcim

Holcim, one of the largest producers of construction material worldwide, relies on drive technology from Nord Drivesystems.In its cement plants and concrete factories in Croatia, geared motors of different performance classes are used. Heavy duty is no problem for the Nord products - they are ready for any challenge. That is why both companies have now completed a threeyear- contract for the exchange of older drives. Nenad Mackic, facility manager in the Sumber quarry, is completely satisfied: We value the drive technology from NORD due to its high reliability and efficiency. Service and delivery availability are also the best. For good reason, we have been operating NORD products in our quarries for more than 10 years without experiencing problems. Holcim for a good ten years, the corporation has been represented in Croatia with six concrete factories, a cement plant and three quarry systems. From the beginning, Holcim Croatia has mostly used drive solutions from Nord Drivesystems for the belt conveyor systems used in these facilities.
