Permanent magnet shaft generators For shaft generators, our mechanical solution based on permanent magnet generators (PMG) and frequency converters allows the auxiliary generators to be off most of the time and enables the ship to operate at variable speed while producing electricity. Higher efficiency A PM machine gives high-efficiency performance over the entire operating range, significantly…
Permanent magnet machines for marine applications Our permanent magnet machines can be operated as a generator or a motor. They are ideal for large low-speed, direct-drive two-stroke engines. Our propulsion motors offer high efficiency with a large speed range. All PM machines are thoroughly tested at our own Large Drive Test Center and fulfill relevant…
Co-juvenating! It’s a new term based on the idea of “rejuvenating” that was created for The Switchians to capture the spirit for their future. It’s a new day, with a new owner – and an enhanced opportunity to succeed.
When working in the manufacturing industry, there are many variables to juggle. Three most common ones are the price of the product, the quality of the product, and the speed of delivery.
The world economy is showing signs of recovery after many years of being battered by the financial crisis. This is vital for the wind industry so that investments flow into the industry, and at the same time, transformation still continues. Announcements of investments in Dong Energy as well as Mitsubishi and Vestas joining forces are good indications that the strong players are ready to invest in the promising offshore wind.
What do wind turbines and summer cottages have in common? They are quite similar. Perhaps not in numbers, but from a technology point of view. Some are equipped with features only considered necessary for survival; others have ultra-modern technical solutions that even enable remote access to monitoring equipment by mobile phone. Both in cottages and turbines, features requested in the 90s may not live up to our needs today.
The gear and generator combination, now in commercial production for DeWind, is a joint effort of The Switch and gear supplier Moventas. FusionDrive® is the most advanced gear and generator combination in the world, with an astonishing efficiency. The overall drive train efficiency with both partial loads and nominal output has proven to be best in class and will lower the cost of wind energy.
Permanent magnet (PM) technology has some clear benefits also for marine applications. Since fuel prices have gone up by 30% in only 2 years and freight rates have remained at about the same level for the past 10 years, energy savings has become hot topic in shipbuilding.
Dear friends, The first half of 2025 has been nothing short of exceptional. I’m proud to share that we’ve reached an all-time high order backlog – an achievement driven by a record-breaking order intake this spring. In just over five months, we’ve already secured more orders than in the full year of 2024. What makes…
This webinar will cover how Berg Propulsion and The Switch matched their joint technology to design a series of low-carbon multipurpose diesel-electric vessels with a controllable-pitch single propeller for Skarv Shipping Solutions. These vessels will be far more climate-friendly than what is currently available in the European short-sea market today. They will also focus on high efficiency and low fuel consumption.
The Switch single drives have been selected as part of a retrofit solution to hybridize a larger fleet of older vessels. The drives will connect batteries to the vessels’ AC switchboards. The Switch drives will be containerized with a battery and transformer by the system integrator and delivered as a single turnkey package. Delivery to…
We’re pleased to announce the successful sea trials of our PMM1000M, PMM1500M and PMM2000M designs. These trials validate earlier design simulations and confirm safe cruising and reliable permanent magnet shaft generator operations. We carried out trials on the Grazyna Gesicka LNG carrier in cooperation with Botnia Engineering, our subcontractor. Efficient energy design The Grazyna Gesicka…
