The full-power liquid-cooled converters are modular, which the company believes will extend the life of the generator and lower maintenance requirements.
Fixed-magnet generators are seen as a better option for offshore turbines due to their higher reliability compared with double-fed induction generators.
Since the generator is intended for geared turbines, it only requires 10% of the magnets needed for a direct-drive generator of the same power rating.
The component will be put through its paces again "in the coming weeks" as it is subjected to full-load tests, the firm said.
