Conventional generators typically depend on substantial iron cores. These cores introduce magnetic resistance and result in energy losses within the core material.
In contrast, our disc-type generator design channels the magnetic flux in an axial direction. This innovative approach removes the need for an iron core entirely, effectively eliminating the associated core losses.
Our latest innovation incorporates the cutting-edge “Precise Coil” technology, which eliminates hysteresis and gear notch effects. This advancement ensures an exceptionally low starting torque of less than 0.3 N·m, enhancing overall performance and efficiency.
We have replaced traditional motors with a disc coreless motor design. This unique approach significantly reduces both the volume and weight of the unit, making it more compact and lightweight without compromising on power.
Utilizing specialized coreless motor technology, our design overcomes the common bottlenecks associated with low-speed wind energy conversion. This results in a higher utilization rate and improved energy harvesting capabilities.
The specially engineered structure offers a superior power-to-volume and power-to-weight ratio. Additionally, it boasts an extended operational lifespan—lasting up to eight times longer than conventional motors—ensuring dependable long-term use.
Featuring a gearless, direct drive configuration, this low RPM generator minimizes mechanical complexity, leading to reduced maintenance requirements and increased durability.
Built with high-standard, quality components, the generator is designed to operate reliably in demanding and extreme conditions commonly encountered in wind turbine applications.
The generator achieves excellent efficiency due to its low mechanical resistance, minimizing energy losses and maximizing output.
An aluminum alloy outer frame combined with a specially designed internal structure ensures effective heat dissipation, maintaining optimal operating temperatures.
Various parameters such as voltage, speed, power, and frequency can be customized according to specific requirements, offering flexible integration possibilities.
Equipped with H class insulation and vacuum pressure impregnation, the motor is well-protected against environmental stresses. Additionally, superior heat dissipation can be further enhanced with optional fan cooling.

This Axial Flux Coreless Generator features low start torque and higher reliability, delivering high efficiency for various power generation applications.
Vertical-axis wind turbines represent a unique type of wind energy technology. Unlike traditional horizontal-axis turbines, these turbines have blades that rotate around a vertical shaft. This design offers advantages in terms of being able to capture wind from any direction without needing to reorient the turbine.
In addition to wind power, small-scale hydropower systems provide an effective means of generating renewable energy from flowing water sources. These systems are typically installed on rivers or streams and are designed to harness the kinetic energy of water to produce electricity on a smaller, more localized scale.
Together, vertical-axis wind turbines and small-scale hydropower technologies contribute to diversified renewable energy solutions, especially suitable for decentralized energy generation and applications in remote or off-grid locations.
