Product Description

Aluminum Alloy Axial Flux Coreless Permanent Magnet Generator Featuring 16 to 48 Poles Air Cooling System Ideal for Renewable Energy and Power Solutions 0

Product Description:

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.


Features:

Torque Patent Technology

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.

Original Structure

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.

Higher Utilization

Utilizing specialized coreless motor technology, this design overcomes common bottlenecks associated with low-speed wind energy applications, resulting in improved efficiency and utilization.

Higher Reliability

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.

Gearless, Direct Drive Design

This generator operates without gears, using a direct drive mechanism at low RPM, which reduces mechanical complexity and maintenance requirements.

Durability in Harsh Environments

Built with high-standard quality components, the generator is designed to withstand extreme and harsh conditions, making it ideal for use in wind turbines.

High Efficiency and Low Energy Loss

It achieves excellent efficiency by minimizing mechanical resistance and reducing energy losses throughout its operation.

Excellent Heat Dissipation

The aluminum alloy outer frame combined with a specially designed internal structure facilitates effective heat dissipation, ensuring stable performance under various conditions.

Customization Options

We offer customization of key parameters such as voltage, speed, power, and frequency to meet specific application requirements.

Advanced Insulation

The product features H-class insulation with vacuum pressure impregnation, enhancing electrical durability and safety.

Enhanced Cooling Capability

In addition to its inherent heat dissipation qualities, the system can be equipped with fan cooling to further improve thermal management.

Applications:

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.

My farm is 30 kilometers from town, and connecting to the power grid would cost a fortune. Three years ago, I installed a solar panel system with a battery bank. It was sufficient during spring, summer, and fall, but in winter, we often had a week of consecutive overcast days—and the batteries would run out in just three days. Last year, I decided to add a variable-pitch wind turbine, connected it to the AC coupling port of the Deye inverter, and set up a hybrid solar-wind system. Throughout the entire winter, the battery level never dropped below 45%, and I never had to work in the dark again. The Deye app allows me to monitor both the solar and wind turbine data simultaneously, and the transition between them is so smooth it’s almost imperceptible. Relying solely on solar power during winter on a Nordic farm is a gamble. Only by combining a variable-pitch wind turbine with a Deye inverter—creating a wind-solar hybrid system—can you get through the winter with peace of mind.

Since installing this variable-pitch wind turbine, the battery hasn’t run low again. Before, I used to worry whenever we had consecutive overcast days and light winds in the winter, but now it can even charge the battery in low winds. Best of all, it doesn’t suddenly start screeching during gusts, so it doesn’t disturb my family’s sleep. The installer also mentioned that variable-pitch turbines are easier to calibrate than fixed-pitch ones. I give it five stars!

I run a small dairy farm in northern Norway, far from the power grid. A few years ago, I installed solar panels and a Deye inverter, but the solar system basically stops working in winter, and the diesel generator was costing me a fortune. This year, I added this variable-pitch wind turbine and connected it to the Deye inverter for a hybrid solar-wind system, and we haven’t had a single power outage all winter. This wind turbine starts up at low wind speeds of just 2–3 on the Beaufort scale. During blizzards, the blades automatically pitch down to slow the turbine, preventing runaway speeds, and it’s much quieter than my neighbor’s fixed-pitch model. The Deye inverter’s switching logic is smart—it prioritizes solar power when available, and automatically switches to the wind turbine when solar output drops. It’s all clearly visible on the app. Now, the diesel generator is practically idle. Wind and solar backing each other up—that’s true off-grid freedom.
