APP CALCULATES DRIVE EFFICIENCY

5/05/2022


AUTOMATION SOLUTIONS MANUFACTURER, WEG, has developed a new app called EcoDrive which allows engineers to calculate the efficiency of their system — be it a variable speed drive (VSD), motor or a combination. WEG EcoDrive is free to download from the Apple App Store or Google Play.

Last year the European Union changed its ecodesign legislation for electric motors. From July 1, 2021, it became mandatory to meet the minimum IE3 energy efficiency levels for three-phase electric motors (from 0.75kW to 1000 kW), and VSDs having their own efficiency levels of IE2.

In light of this, WEG has developed the app to ensure engineers are in line with the new legislation. It automatically calculates the eight operating points of the VSD and of the system and provides the ability to check the efficiency class of the motor.

“Our app helps to demonstrate the efficiency and losses of WEG inverters and motors in accordance with IEC61800-9-1 and IEC 61800-9-2,” said Marek Lukaszczyk, Marketing Manager for Europe and the Middle East at WEG. “Avoiding energy waste is crucial for sustainable consumption.
“The regulations regulate the efficiency of VSDs by subjecting them to information requirements such as energy efficiency at different load points in terms of speed and torque. WEG has a complete line of VSDs that exceed the requirements established by the new directive.”
