ABB ACS 6000 multidrive provides speed control for wind turbine test benches CENER
This document presents the ACS 6000 medium‑voltage variable speed drive used to power the Azipod® propulsion system on the US Coast Guard Great Lakes icebreaker. It explains how the drive’s full‑torque capability improves manoeuvrability and operability in heavy ice conditions.
The case note also details the PEBB (Power Electronic Building Block) technology behind the ACS 6000, its modular concept, key technical data, and the benefits such as high reliability, high power density, and reduced noise and vibration.
