10 years in the shaft generator business – A short review

Looking at my email history, I see that the term “shaft generator” first appeared in my email conversations in May 2013. So, it has been exactly ten years to date from when we first started to think how we could utilize our permanent magnet technology originally developed for the wind industry in marine applications –…

Reliable power system with ultra-fast fault response time for DP vessels

Delivering a vessel with Dynamic Positioning (DP) classification can be challenging. And the higher the DP rating, the more difficult it can be. Luckily, there are experts delivering DP systems that can handle both the complex force calculations for the steering and the failure modes and effects analysis (FMEA) for such a complex system. But…

Cooling options for high-speed solid rotor machines

Did you know you can choose from a variety of effective cooling systems for our high-speed solid rotor electrical machines? Solid rotor machines are a superb option for high-speed applications because they are robust, efficient and reliable. But because high-speed machines are characterized by high power density, even with the highest efficiency the loss density…

Technical notes for swift and accurate system integration

System integrators face many more complex requirements and challenges with today’s increasingly versatile and comprehensive systems for propulsion and the production of onboard electricity. As a result, system integration must now start much earlier. This means information on system components must be available earlier, especially in the case of unfamiliar new technologies and solutions that…
