According to Nord, the costs for administration, maintenance and wear can be reduced by using suitable drive systems. The Nord Eco box can measure the energy consumption of individual drives in detail and allows for extensive data analysis.
Jörg Niermann, head of marketing at Nord, said: “The Nord Eco box contains an energy measuring device that measures the drive’s current and voltage. It determines the effective or reactive power, i.e. the energy actually used or not used, and from this calculates the relative power factor.”
After installation of the Nord Eco box between the drive and power supply, data covering permanent loads, load peaks and irregular conditions is recorded over a period of two months. Measuring over the entire period creates data that can identify patterns and random outliers, allowing a load cycle of the entire system to be created.
Once the survey is completed, Nord evaluates the data. The customer receives the evaluation in the form of a PDF document which presents the main key data.
In the evaluation of the results, the data recorded makes it possible to determine whether the dimensions of a system meet the requirements of the respective application or whether the system is oversized, for example, which is particularly important when optimising for energy efficiency.
In large systems with numerous drives – such as in intralogistics – the Nord Eco service can help to optimise the power used by the individual drive systems and reduce the number of different systems. This helps further streamline production, logistics, storage and service processes. The motors from Nord provide a constant torque over a large speed range and are particularly suitable for a reduction of variants.
Together with the data evaluation, the customer receives a recommendation for an efficient Nord drive solution. The energy balance of the Nord solution is documented as part of a further measurement and the customer can see their increase in efficiency in writing.
“The Nord Eco service has already helped various customers to improve the energy efficiency of their production and thus to reduce their carbon footprint”, Niermann added.
