Product Description
Aluminum Alloy Coreless Permanent Magnet Generator
Product Overview

Conventional generators typically depend on heavy iron cores, which contribute to magnetic resistance and result in core losses during operation. Our innovative disc-type design channels the magnetic flux along the axial direction, entirely eliminating the need for an iron core. This unique approach reduces magnetic resistance and minimizes energy losses, leading to improved efficiency and performance.

Applications

Vertical-axis wind turbines represent a unique category of wind energy technology. Unlike common horizontal-axis turbines, these machines have their main rotor shaft arranged vertically, allowing them to capture wind from any direction. This makes them particularly suitable for urban or complex wind environments.

Small-scale hydropower systems offer another sustainable option for generating electricity. These installations harness the energy of flowing water on a limited scale, suitable for local or individual use. They provide a reliable and renewable power source, especially in rural or off-grid areas.

Both vertical-axis wind turbines and small-scale hydropower are integral components of decentralized renewable energy solutions, contributing to reduced dependence on fossil fuels and promoting environmentally friendly energy production.

Customization Options

Greef offers customized Axial Flux Coreless Generators under the model number GDG. Our permanent magnet generators feature a coreless structure and are designed to deliver large output power with high power density, making them ideal for various industrial applications.

As an inner-rotor generator, the GDG model operates efficiently across a rated power range of 50W to 100kW and a rated rotor speed between 60rpm and 700rpm. All units are CE certified, guaranteeing quality and reliability.

This canal flows day and night – I never thought it could make money. After Greef installed the system, it runs by itself. Every day I check my phone to see how much electricity was generated and how much I earned. I'll recover my investment in less than a year, and after that it's pure profit.

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.

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.
