ABB Permanent Magnet Shaft Generator and ACS880 Drive Package
Pre-engineered package pairing an in-line permanent magnet shaft generator with an ACS880 variable speed drive, 1500–4000 kW, for PTO, PTI, PTH and shore power on container ships, tankers, gas carriers and dry cargo vessels.
Description
ABB's permanent magnet shaft generator and ACS880 drive package pairs an in-line PM shaft generator with a variable speed drive as one pre-engineered solution. Resolving system interfaces upfront supports vessel efficiency and EEDI/EEXI/CII compliance, with up to 4% fuel savings stated, for both newbuild and retrofit projects.
Key features
- Variable-speed generation independent of shaft speed
- Compact installation footprint
- Lower interface risk through a coordinated generator and drive package
- Digital connectivity for predictive, condition-based maintenance (lifecycle cost reduction of up to 20% stated)
Operating modes
- Power Take Off (PTO)
- Power Take In (PTI)
- Power Take Home (PTH)
- Shore power
Package configurations

|---|---|---|---|---|
| 1120A_20 MNM | ACS 880-LC 3 x R8i + 2 x R8i | 1500 | <1660 | Dry cargo vessels, tankers |
| 1120A_20 MNM | ACS 880-LC 4 x R8i + 3 x R8i | 2050 | <2470 | Gas carriers |
| 1400A_20 MNM | ACS 880-LC 5 x R8i + 4 x R8i | 2350 | <3260 | Gas carriers |
| 1400A_20 MNM | ACS 880-LC 6 x R8i + 5 x R8i | 3050 | <4050 | Container vessels |
| 2000A_36 MNM | ACS 880-LC 8 x R8i + 6 x R8i | 4000 | <4840 | Large container vessels |
| 2000A_36 MNM | ACS 880-LC 8 x R8i + 7 x R8 | 4000 | <5650 | Large container vessels |
Shaft generator current depends on the vessel's operating point (speed, torque, power). Converter nominal power depends on grid voltage and short-circuit current level; table values are for the 690 V / 180% SCC option.
Applications
Container ships, tankers, gas/LNG carriers, bulk and dry cargo vessels, and ferries.
