Conventional generators depend on substantial iron cores, which introduce magnetic resistance and result in core energy losses. These iron components are typically heavy and limit the efficiency of the generator.
In contrast, our innovative disc-type design channels the magnetic flux along the axial direction, thereby removing the need for an iron core entirely. This approach effectively eliminates the issues related to magnetic resistance and core losses.
By adopting this iron-free configuration, our design enhances performance and reduces the weight of the generator, offering a more efficient and compact solution compared to traditional models.
Our product utilizes the latest "Precise Coil" technology, which effectively eliminates hysteresis and gear notch effects. This innovation results in an exceptionally low starting torque of less than 0.3N·M, ensuring efficient and smooth operation from the onset.
By replacing traditional motors with a disc coreless motor, the design significantly reduces both the volume and weight of the device. This advancement contributes to a more compact and lightweight solution without compromising performance.
The integration of specialized coreless motor technology overcomes common limitations associated with low-speed wind energy applications. This improvement leads to higher efficiency and better utilization of available wind resources.
Featuring a unique structural design, the motor achieves a superior power-to-volume and power-to-weight ratio. Additionally, it boasts a lifespan that is eight times longer than that of traditional motors, ensuring long-term dependable performance.
This is a gearless, direct drive generator operating at low RPM, which contributes to reduced mechanical complexity and enhanced durability.
High-standard quality components are selected to withstand harsh and extreme environmental conditions, making this product ideal for use in wind turbine applications.
The design features high efficiency and minimized mechanical resistance, resulting in reduced energy loss during operation.
The aluminium alloy outer frame, coupled with a specially designed internal structure, ensures excellent heat dissipation. Additionally, the system can be equipped with fan cooling for enhanced thermal management.
Various parameters such as voltage, speed, power, and frequency can be customized to meet specific requirements, providing flexibility to suit different applications.
The product features H class insulation and vacuum pressure impregnation technology, enhancing its durability and resistance to electrical stresses.

Vertical-axis wind turbines (VAWTs) represent a distinct type of wind energy technology where the main rotor shaft is set vertically. Unlike the more common horizontal-axis wind turbines, VAWTs can capture wind from any direction without the need for reorientation. This characteristic makes them especially suitable for urban environments and locations with turbulent wind conditions. Additionally, their compact design often allows for easier installation in smaller spaces.
Small-scale hydropower refers to hydroelectric power installations that generate a relatively low amount of electricity, typically serving localized communities or individual facilities. These systems harness the kinetic energy of flowing water in rivers or streams without the large dams associated with conventional hydropower plants. The minimal environmental impact and ability to provide reliable, renewable energy make small-scale hydropower an attractive option for sustainable development in remote or rural areas.
