GreenSpur Rethinks Generators for More Efficient Wind Turbine Operations
If you manage wind turbine operations, you’re probably acutely aware of just how much generator weight, complexity, and maintenance affect uptime and cost. In a recent Spotlight interview with the Uptime Wind Energy Podcast, Jason Moody, Chairman, GreenSpur Wind, explained how the company’s axial‑flux technology is reshaping generator design to meet today’s offshore and floating wind challenges.
Listen to the full interview to learn how GreenSpur is putting a whole new spin on wind turbine design
The Weight Problem and The Axial-Flux Solution
It’s typical for today’s direct‑drive generators used in offshore turbines to weigh more than 150 tons. Big machines for big jobs, right? But that weight has a structural ripple effect: heavy generators necessitate heavier towers, reinforced foundations, thicker steel, and larger blades— and all of that heft increases capital and installation expenses, initially, and contributes to ongoing maintenance and operations expenses.
When large generators are needed on floating platforms, those dynamic loads require even heavier ballast; structural integrity gets more complex. Some floating wind designs have tested hybrid and geared systems to reduce weight, but combined systems add complexity. While the industry’s goal, always, is to reduce LCoE, larger systems weigh more, and more complicated designs rarely improve efficiencies.
So for floating wind installations, particularly, GreenSpur’s axial-flux design – with a significantly reduced weight – offers clear advantages.
As Moody points out, hybrid and geared systems can be “even more complicated” – and not just on electrical efficiency.
“As they spin faster, they get hotter, and then…you need more high-tech cooling systems, which is another point of failure,” he said.
“So the LCoE really does start to suffer with these more complex, advanced systems.”
“What we’re trying to do is introduce a new technology that can address the problem (of excess with) and hopefully address some other problems as well.” – Jason Mondy, GreenSpur
What are the Advantages of Axial Flux Generators?
While most traditional radial-flux generators have concentric cylinders where magnetic flux flows between them (see more here), Greenspur’s axial flux design has the rotor and stator arranged as discs along the axis of the machine, and the magnetic flux flows parallel to this axis.
Because Greenspur’s axial flux generator employs a modular architecture, multiple smaller stages can be connected in parallel. This allows for easier scaling, customization, and potentially a lighter overall design for higher-power applications.
GreenSpur’s axial-flux generators are significantly lighter than traditional radial motors. And, unlike current generators that need active cooling systems (which bring their own maintenance headaches), axial‑flux machines reduce or eliminate this demand.
Also, because GreenSpur’s designs work with a variety of magnets – from low-cost ferrite to rare-earth materials – they offer a lot of cost control options, too.
How does an axial flux generator work? Uptime explains everything.
The Wheels are Turning Now
While axial flux is not a new design concept, GreenSpur’s implementation puts a new spin on things. Where else are axial flux design used? In Lamborghini’s Temerario, pictured, as well as in high-end vehicles from Mercedes Benz, Ferrari, Jaguar and other manufacturers.

Other Operational Impacts for Turbine Installation, Maintenance
Lower weight means fewer cranes and smaller barges. Translation: Easier, less-expensive installation and repairs
Structural Compatibility is a lifetime benefit, as axial-flux components could slot into new turbines with few structural upgrades, and make retrofitting existing foundations easier
No active cooling means lower maintenance costs, as there are few issues with fluid leaks, fans and pumps.
Strategic Moves for Owners, Operators, and Managers
Axial‑flux generators offer a fresh paradigm: lighter weight, simpler design, potential cost reductions, and enhanced suitability for offshore and floating farms. For operations managers – and also investors – this is welcome news because it also means: shorter installation times, lower and less-costly maintenance, and simplified inventories.
Although axial-flux turbines aren’t yet mainstream, the promise of reducing the LCoE combined with more streamlined, efficient operations, is a powerful lure to get behind the technology.
Those who want to learn more about axial-flux integration, pilots or trial deployments should contact GreenSpur. As axial-flux engine production is already scaling up in the automotive industry, it will soon be wind energy’s turn to benefit from the technology and design.

How to Prepare for Axial Flux Generators?
Tips and considerations for those ready for this efficient upgrade to wind turbine operations include:
Training: O&M crews must understand axial‑flux-specific drive electronics, winding structures, and maintenance procedures. proactive training plan will be essential.
Pilot Programs: Collaborate with GreenSpur or OEMs to install axial‑flux prototypes on pilot turbines, ideally in planned outages or new builds.
Develop Inspection Protocols: Begin documenting how axial‑flux units behave under load, vibration, thermal cycling, and blade pitch events.
Evaluate Asset Life Cycle Savings: Estimate savings from reduced downtime, simpler maintenance, lighter lifts, and material costs to put real numbers behind expected gains.

As Europe Shuns Chinese Turbines and Components, Who Will Fill the Gap?

As Europe Shuns Chinese Turbines and Components, Who Will Fill the Gap?
While most of Europe has spent most of this year itemizing reasons it cannot, should not, and will not use Chinese wind turbines or components, accusations and arm-twisting tactics have garnered most of the attention.
But we invite you to consider a future – maybe just five, or ten years from now?- in which those same countries and companies are eagerly awaiting orders from wind turbine manufacturing facilities in… India.
What?!
You know that the country has a lot of installed wind.
You may think – and many in the industry would agree – that India’s blade manufacturers are a few revs behind blade-makers elsewhere in the world. But the country is newly committed to manufacturing and it’s busy installing more – provided that it’s made in India, with Indian technology, by Indian workers.
Of course, similar domestic-focused policy currents are running through European countries – where wind OEMs are almost inarguably a decade ahead of Indian manufacturers. But there’s an important reason why we say, “watch India” in wind turbine manufacturing.
It’s because you might learn something.
If you follow The Uptime Wind Energy Podcast, you probably heard this discussion a few weeks ago. It wasn’t the headline story – we try to highlight as many major news items and trends that we can, and follow up as credible information becomes available. India’s quiet moves to strengthen its own renewable energy industries didn’t grab the headlines. But it comprised a good bit of our panelists’ discussion.
With India’s expanding manufacturing capacity, and Suzlon’s strategic offerings for the European market (Blue Sky), there are reasons for European developers to take a closer look at Indian manufacturers.
If Europe continues to squelch deals with Chinese manufacturers due to data security issues, India is a relatively obvious candidate to fill the void, for several reasons:
- The country has depth and breadth in R&D: India (Suzlon, specifically) has a track record of involvement and relationships across the continent, as it operates research and development centers in Germany, the Netherlands, and Denmark.
- Indian service providers have reach: Inox and Adoni Wind operate multiple wind turbine manufacturing plants and wind farms throughout several Indian states, and Apraava Energy has been commissioning wind projects, working with multiple OEMs, for more than 16 years.
- The country’s energy sector has size: Tata Power is estimated to be worth about US$16 billion and employs 22,000 people.
And major manufacturers from other countries have had a strong presence in the country for years:
- GE Vernova has turbine blade and nacelle manufacturing operations and multiple tech/R&D centers in India;
- Vestas has a R&D technology center in Chennai; and
- China’s SANY Wind has had assembly facilities in India since 2017, and in 2024, it signed a licensing agreement with JSW allowing SANY to manufacture blades and generators for JSW – enabling JSW Neo Energy to produce wind turbine generators and major components in-country.
So while there is hard data suggesting that India is already a global hub for wind turbines, sometimes the real strength comes from soft skills. Like sharing information.
We’ve noticed that Indian manufactures aren’t stingy with information. They share what they learn in the field and on the shop floor, so that the whole industry can move faster to solve problems. That bodes well for the industry overall, and particularly well for companies who figure out how to solve problems that some manufacturers aren’t even ready to admit to having.
We’ll be watching India with a great deal of interest in the coming months. Subscribe to The Uptime Wind Energy Podcast and follow along with us.
We’re not financial analysts. We’re engineers who watch the wind industry very closely. This is what we’ve noticed, and we thought it was worth sharing.
Where do you think you’ll be looking for solutions, components, and service providers in the next few years or the next decade? Tell us what you think. We’d love to hear from you.

When You Write for Idiots, You Can Get Away with Anything
To the author of the meme here:
“Either” refers to two choices; “any” refers to three or more.
More importantly, it’s amazing how shamelessly the ultra-right wing exaggerates. The left side of the Democratic party would like to see the United States look like social democracies in places like Scandinavia. Having government programs that benefit the common person, e.g., Social Security, public schools, emergency relief, libraries, environmental responsibility, etc., does not equate to Stalinism.

Are Muslims “Dangerous?”
Some of my old prep school chums from the Class of 1973 convene via Zoom approximately every six weeks for a 90-minute discussion of current events, science, and anything else that sounds interesting.
Our professions range from medicine, law, finance, and business management. All from highly ranked colleges. Over 50% hold doctorate degrees.
Here’s something I find fascinating about the group: it includes one right-wing conservative. I don’t mean a Reaganite; I mean a Trump supporter. This guy is incapable of any thought that doesn’t come directly from Nexsmax.
It’s almost eerie how closely he toes the line of the far-right. Yesterday he echoed the Newsmax talking point and told the group that all Muslims holding public office are “very dangerous” and should be removed.
Now, the rest of us are sitting there, dumbfounded at this idea, unwilling waste our breath on this racist and utterly preposterous concept.
All this raises the question: How are our political viewpoints formed? How much of this is genetics? Epigenetics? Early childhood experiences? How do take a boy from among the best environments and turn him into someone who struggles to understand the most basic principles on which our country was founded?
