We just got back from the ASME Turbo Expo and Conference in Rotterdam where many were asking how turbo will fit into future energy solutions.
Everyone in the industry seems to be waiting, hesitating to move forward until it’s known which renewable or green gas will best address climate change – and how compressor and turbine applications will need to adapt to handle the new situation. Yet everyone must be ready to move once decisions are made.

Extending the power and speed capabilities of standard induction electric motors
The Switch solid-rotor technology extends the speed capabilities of standard induction electric motors, filling the existing gap for applications running below multi-megawatt powers. Typically, standard 2-pole induction motors reach speeds of 3,000–3,600 rpm and with a variable frequency drive (VFD), can reach speeds up to 4,500 rpm. In high-speed applications, a high-speed gearbox together with…
Testing verifies safety of permanent magnet shaft generators
Jussi Puranen Safety is one of the biggest worries for shipowners and operators unfamiliar with PM technology. They want to know they’re protected from fault currents even when the magnetic field cannot be switched off. We at Yaskawa Environmental Energy / The Switch take all kinds of safety issues very seriously and have thoroughly examined…
Dimensioning the shaft line for a shaft generator or propulsion motor
Patrik Holm If you’re considering a shaft generator or propulsion motor for your vessel design, you already know you’ll be saving on fuel consumption, improving efficiency, and complying with the current EEDI and EEXI emission limits. With an electric machine on the shaft line, we face new considerations in shaft line dimensioning. The bearings in…
New test center verifies large marine electrical drives
Panu Kurronen Marine engineers, investors and builders are in a tight spot these days. There’s the pinch of approaching regulation deadlines and the stress of using new technology rather than familiar, well-tried equipment. We understand. Change is costly and stressful. We’ve been exploring and expanding PM machine technology for two decades, first for wind power…
Solving marine DC distribution, selectivity, redundancy and safety issues
Teemu Heikkilä The marine industry is evolving rapidly to meet 2023 IMO-mandated emissions deadlines – and the ones to follow. To accomplish this, long-established methods and equipment are being reevaluated, upgraded or replaced. Making DC distribution the best choice for marine use Power distribution is a promising area for vessel efficiency gains. Although AC distribution…
New PM shaft generator provides higher power output for marine needs
Over the last decade, inline PM shaft generators have become increasingly popular for large merchant vessels. Now our newest PM shaft generator PMM2000M offers the large container vessel market the same benefits of our lower-powered shaft generators.
New concepts for powering vessels
In the marine industry, the future looks highly interesting, with major challenges to unravel. The energy mix on board is likely to be a fascinating mosaic. Our vessels have to be ready, and flexibility will be key.

What could the most robust high-speed technology do for your application?
If you want a simplified drive system with better efficiency, higher speeds, higher powers and safety, our solid rotor machines are the answer.
Why permanent magnet machines outperform induction machines?
A study we made during summer 2021 quantified impressive permanent magnet (PM) machine efficiencies for vessels like LNG and LPG carriers that often utilize slow-speed, direct-driven in-line shaft generators producing electrical power from two-stroke main engines.
Future tools are already here
The marine industry is looking for ways to comply with looming emission regulation deadlines and prepare for the future. Possible solutions include a host of alternative fuels, further electrification and greater efficiency of current solutions.
