“The first step is the comprehensive collection of measurement values”, Jörg Niermann, Head of Marketing at NORD, explains. “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 a high density of data that can identify patterns and random outliers, allowing a load cycle of the entire system to be created.
Evaluation of the data
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 large amount of data recorded makes it possible to determine precisely 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.
Reduction of variants
In large systems with numerous drives – such as in intralogistics – the NORD ECO service can help not only to optimise the power used by the individual drive systems, but also to reduce the number of different systems. This helps to further streamline production, logistics, storage and service processes. The high-efficiency 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”, says Niermann.
