Energy saving made easy

According to expert estimates, electric drives account for 70 percent of the total energy consumption of all industries! The NORD ECO service helps companies to reveal optimisation and energy-saving potential and to find the most efficient drive solutions.

For this purpose, the so-called NORD ECO BOX, a mobile control cabinet, is connected between the motor and the power supply. The NORD ECO BOX consists of an energy measuring device with data logger function, current transformer and cable connections. Over a period of about two weeks, the box records data in real time about permanent loads, load peaks and irregular conditions. Once the survey is completed, the results are uploaded to software developed by NORD that automatically evaluates the data.

Identifying overdimensioning and optimising systems

“The measurements over time make it possible to create a load cycle for the system. This shows whether a system’s dimensioning corresponds to the requirements of the respective application”, Niermann, Head of Marketing at NORD, explains. “We often see drive systems that are oversized for the corresponding application.” If a system is driven with the drive recommended by NORD, the company offers to carry out a remeasurement. As part of a TCO analysis (Total Cost of Ownership), the most cost- and energy-efficient solution can then be determined.

For large systems, such as in intralogistics, the NORD ECO service analysis can significantly reduce the number of different drive systems. This helps to minimise administrative costs and streamlines production, logistics, storage and service processes. NORD offers high-efficiency motors with constant torque over a large speed range, which are ideally suitable for variant reduction.
