NORD assists businesses in selecting the most cost-effective drive option for their needs through its ECO service. Utilizing appropriate drive systems can cut costs for administration, upkeep, and wear as well as energy consumption and CO2 emissions. The NORD ECO box permits extensive data analysis and can precisely measure the energy consumption of individual drives.
Jörg Niermann, Head of Marketing at NORD, explains, “The comprehensive collection of measurement values is the first step.” The NORD ECO box contains an energy estimating gadget that actions the drive’s current and voltage. It calculates the relative power factor from the effective or reactive power, also known as the energy used or not used.
Over the course of two months, data covering permanent loads, load peaks, and irregular conditions is recorded following the installation of the NORD ECO box between the drive and power supply. A load cycle of the entire system can be created by measuring over the entire period, which results in a high density of data that can identify patterns and random outliers.
Evaluation of the data
NORD analyzes the data following the completion of the survey. The evaluation is sent to the customer as a PDF file that contains the most important information.
A large amount of recorded data makes it possible to precisely determine, during the evaluation of the results, whether the dimensions of a system meet the requirements of the particular application or whether the system is oversized, which is especially important when optimizing for energy efficiency.
Reduction of variants
The NORD ECO service can help reduce the number of drive systems and optimize the amount of power used by each drive system in large systems with multiple drives, such as intralogistics. This aids in further streamlining the processes of production, logistics, storage, and service. NORD’s high-efficiency motors are especially suitable for a reduction of variants because they provide constant torque over a wide speed range.
The customer receives a recommendation for an effective NORD drive solution in conjunction with the data evaluation. As part of subsequent measurement, the NORD solution’s energy balance is documented, and the customer can write down their increased efficiency.
According to Niermann, “The NORD ECO service has already assisted a number of customers to improve the energy efficiency of their production and, as a result, to reduce their carbon footprint.”
