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.

A milestone built on trust and reliability

Dear friends, With the first quarter behind us, it is a good time to share an important milestone in our marine business. We have now exceeded 600 permanent magnet (PM) marine machines ordered, with more than 300 already delivered and operating at sea. Even more importantly, this growing installed base has accumulated over 5 million…

Freedom to think beyond

LUT Blossom 2026 was created as a business growth event to help research and commercial collaboration translate into real-world impact. Organized by LUT University for the very first time on Friday, April 10 in Lahti, Finland, the event gathered more than 1,400 attendees from academia, industry and government. One of the main topics of focus…

A green rescue for reefers with PM shaft generators

Over the past decades, there’s been a dramatic increase in the amount of sea freight being shipped – now over 80% of all cargo is transported overseas. In increasing frequency, companies need to maintain major energy-consuming vessels to cool and ship meat, fruits and vegetables to global markets.

The Switch signs deal for permanent magnet shaft generators

The Switch and WE Tech signed an agreement for the delivery of four direct-drive 1.5 MW PM shaft generators. This strengthens the position of The Switch as it uses its proven track record of applying PM generator technology successfully in the wind power industry now to a range of marine applications.

From power generation to propulsion: expanding the role of permanent magnet technology

Recent geopolitical tensions in the Middle East have driven energy prices sharply upward, further pushing the global transition away from fossil fuels. Across industries, this shift is becoming increasingly urgent – and in the maritime sector, it is reinforcing the business case for electrification. As fuel costs rise and emissions regulations tighten, electrification is reshaping…

Why smaller ships need a new generation of compact electric machines

Electrification is steadily reshaping ship power systems across the maritime industry. From battery-powered ferries and hybrid offshore vessels to large container ships using shaft generators and power take-off systems, electrical machines are becoming a central part of modern vessel design. However, the engineering challenges behind electrification can vary significantly depending on vessel size and operating…

20 questions about permanent magnet machines

When it comes to marine electrification, permanent magnet (PM) machines are quickly becoming the preferred choice for shipowners aiming for sustainability and cost savings. But as with any new technology, questions arise. We’ve compiled the 20 most frequently asked questions about The Switch PM machines. If you want to understand the technology better, this guide…
