Product Description

Product Description:

An axial flux ironless core generator generates electricity by using an axial flux design and an ironless core structure. Traditional generators are usually associated with iron core losses and hysteresis losses. However, this type of generator avoids those losses.

Typically, the structure of this kind of generator has permanent magnets, coils, and a casing. The permanent magnets help produce the magnetic field; the coils capture the energy in the magnetic field and convert it into electrical energy, while the casing safeguards the internal structure of the generator and offers a solid support.

The functioning principle of axial flux coreless generators is based on electromagnetic induction. When the magnetic field produced by a permanent magnet moves in relation to a conductor in a coil, an induced electromotive force is created in the conductor. This electromotive force can be transformed into electrical energy to power external devices.

 

Applications:

Wind Power Generation:

Axial flux coreless generators have shown great potential in wind power generation, particularly in megawatt-class wind turbines. These generators increase output density and efficiency of wind power generation.

The absence of an iron core reduces iron losses and hysteresis losses, thus making the generator more efficient.

Renewable Energy:

Axial flux coreless generators are not limited to wind power generation; they are widely utilized in renewable energy applications, such as solar and wind power generation systems. Their efficient energy conversion capacity and reliable performance make them an ideal choice for renewable energy systems.

Other Industrial Applications:

Axial flux coreless generators can also be applied in various other industrial settings that require efficient, lightweight and consistent power supply. For example, they can be utilized as backup or auxiliary power sources for deliver steady power support to industrial equipment.

Customized Applications:

Due to the customizable structure of the axial flux ironless core generator, its parameters such as generator power, speed, and output voltage can be tailored to fit customer-specific needs. As a result, the generator can be adjusted to meet the requirements of various application scenarios.

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.

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.
