GreenSpur delivers cutting-edge Axial Flux Permanent Magnet Generator (AF PMG) designs tailored for both onshore and offshore wind applications. Our innovative approach maximises efficiency, reduces operational costs and eliminates reliance on advanced materials, setting new standards for sustainability and performance in wind energy generation.
Onshore Wind – Scalable, Cost-Effective and Sustainable
Onshore wind remains one of the most established and rapidly growing sources of renewable energy. As demand for high-efficiency wind turbines increases, our AF PMG designs provide a competitive advantage by enhancing power output while reducing complexity and maintenance needs.
Why Choose AF PMG for Onshore Wind?
- High Efficiency – Our generators optimise power conversion at variable wind speeds, ensuring consistent energy output.
- Low Maintenance – A Multi-stage rotor-stator structure, simplified concentrated coils, in combination with an optimised passive cooling architecture reduces the complexity of the design, and in turn the cost of service and maintenance Scalability – Our multi-stage stackable generator designs support a range of turbine sizes, from small, distributed energy projects to large-scale wind farms.
- Sustainability – By avoiding the use of , we ensure a lower environmental impact without compromising performance.
- Our technology is adaptable to various onshore turbine configurations, including both traditional Horizontal Axis Wind Turbines (HAWTs) and emerging Vertical Axis Wind Turbine (VAWT) designs.
Offshore Wind – Reliable and Durable for Extreme Environments
Offshore wind power is expanding rapidly, driven by advances in floating turbine technology and deep-water installations. Offshore turbines require generators capable of withstanding harsh marine conditions while delivering maximum energy efficiency.
Our generator designs provide key advantages for offshore applications:
- Corrosion-Resistant Materials – Engineered to endure saltwater exposure and extreme weather conditions, ensuring long-term reliability.
- High-Power Density – Compact and lightweight, our designs help reduce turbine weight, minimising structural loads and installation costs.
- Optimised for Floating Turbines – Our AF PMG technology is adaptable to the growing deployment of floating offshore wind farms, enhancing performance in deeper waters.
By leveraging our innovative generator designs, offshore wind operators can increase energy production, reduce maintenance costs and improve long-term profitability.
Vertical Axis Wind Turbines (VAWTs)
While Horizontal Axis Wind Turbines dominate the market, there is increasing interest in the potential of VAWTs, particularly in urban, distributed and offshore applications. Our AF PMG designs are ideally suited for VAWTs, offering high efficiency and flexibility for this emerging technology.
Key Benefits of AF PMG for VAWTs:
- Compact and Lightweight – Ideal for space-constrained environments, including urban and rooftop installations.
- High Torque at Low Speeds – Efficient power generation even at lower rotational speeds, a crucial advantage for VAWT systems.
- Simplified Maintenance – With simplified and multistage- stackable structure our designs enhance the reliability of VAWT installations.
- Applicability to Offshore Floating Platforms – VAWTs are gaining traction for floating offshore wind farms, where their omnidirectional nature offers advantages over traditional HAWTs.
- While VAWTs are still developing commercially, our generator designs provide the efficiency, durability and flexibility needed to accelerate their adoption in the renewable energy sector.
