Conventional generators typically use heavy iron cores in their construction. These cores create magnetic resistance, which can reduce the overall efficiency of the generator.
In contrast, our innovative disc-type design channels the magnetic flux along the axial direction. This unique approach allows us to completely remove the iron core from the generator.
By eliminating the iron core, our design significantly reduces core losses and magnetic resistance, resulting in enhanced performance and efficiency.
Our product incorporates the latest "Precise Coil" technology, ensuring minimal hysteresis and eliminating gear notch effects. This innovation allows for an exceptionally low starting torque of less than 0.3 N·m.
By replacing traditional motors with a disc coreless motor design, the overall size and weight are significantly reduced, offering a more compact and lightweight solution.
Utilizing specialized coreless motor technology, this design overcomes common bottlenecks associated with low-speed wind energy applications, resulting in improved efficiency and utilization.
The unique structure delivers a superior power-to-volume and power-to-weight ratio. Additionally, it boasts a lifespan that is eight times longer than conventional motors, enhancing durability and performance.
This generator operates without gears, using a direct drive mechanism at low RPM, which reduces mechanical complexity and maintenance requirements.
Built with high-standard quality components, the generator is designed to withstand extreme and harsh conditions, making it ideal for use in wind turbines.
It achieves excellent efficiency by minimizing mechanical resistance and reducing energy losses throughout its operation.
The aluminum alloy outer frame combined with a specially designed internal structure facilitates effective heat dissipation, ensuring stable performance under various conditions.
We offer customization of key parameters such as voltage, speed, power, and frequency to meet specific application requirements.
The product features H-class insulation with vacuum pressure impregnation, enhancing electrical durability and safety.
In addition to its inherent heat dissipation qualities, the system can be equipped with fan cooling to further improve thermal management.

Vertical-axis wind turbines represent a unique type of wind energy technology distinguished by the orientation of their rotational axis. Unlike traditional horizontal-axis turbines, these vertical-axis models have blades that rotate around a vertical shaft. This design allows them to capture wind from any direction, making them particularly useful in environments where wind direction is variable.
In addition to wind energy solutions, small-scale hydropower systems provide an effective way to generate electricity by harnessing the energy of flowing water on a smaller, more localized scale. These systems are typically designed for individual homes, farms, or small communities, offering a sustainable and renewable power source without the need for large dams or extensive infrastructure.
Together, vertical-axis wind turbines and small-scale hydropower installations contribute to the diversification of renewable energy options. They support decentralized power generation, reduce dependence on fossil fuels, and promote environmentally friendly energy practices.
