In-line shaft generators

Efficiency and reliability with fewer emissions

ABB's latest in-line permanent magnet shaft generator offers shipbuilders and operators enhanced efficiency, performance, and reliability.

By cutting CO₂ emissions, it supports compliance with IMO's EEDI and EEXI standards. Designed for easy integration across various vessel types - like bulk carriers, container ships, LNG tankers, and ferries - it delivers up to 4% fuel savings and significant emission reductions.

Optimized for converter control, it outperforms induction and synchronous machines at all loads, while its compact, lightweight design reduces system footprint by around 20%.
