Product Description

Product Description:

Definition

An axial flux ironless core generator is a type of generator that has a unique design of an axial flux and an ironless core. The generator is used to generate electricity through the utilization of axial magnetic flux, all while avoiding iron core losses and hysteresis losses that are common in conventional generators.

Structure

The axial flux ironless core generator is typically made up of three main components: permanent magnets, coils, and casing. The permanent magnets are responsible for generating the magnetic field that is required for the generator to produce electricity. The coils are responsible for converting the energy in the magnetic field into electrical energy. Lastly, the casing provides protection to the internal structure of the generator and offers a sturdy support.

Principle of Operation

The operation of the axial flux coreless generator is based on the principle of electromagnetic induction. When the magnetic field produced by a permanent magnet moves in relation to a conductor that is situated in a coil, an emf is induced in the conductor. This emf is then further converted into electrical energy, which provides power to external devices.

Overall, the axial flux ironless core generator is a unique type of generator that provides an efficient and effective way of generating electricity.

Applications:

Wind Power Generation

Axial flux coreless generators have shown great potential in wind power generation, especially in megawatt-class wind turbines. These generators can significantly increase the output density, thus improving the efficiency of wind power generation. The absence of an iron core reduces iron losses and hysteresis losses, making the generator more efficient.

Renewable Energy

Axial flux coreless generators are not only used in wind power generation, but also in a wide range of renewable energy applications such as solar power generation systems. Their efficient energy conversion capability and reliable operation make them ideal for renewable energy generation systems.

Other Industrial Applications

The axial flux coreless generator can be used in various industrial applications that demand efficient, lightweight, and reliable power supply. For instance, it can be used as a backup or auxiliary power source to provide stable power support to industrial equipment.

Customized Applications

With the flexible structure of the axial flux ironless core generator, it can be tailored to meet the specific needs of customers. For example, generator power, speed, and output voltage parameters can be adjusted to meet the requirements of different 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.

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 built a small pico hydro system on the creek behind my off-grid cabin. The water head is only 3 meters and flow rate around 0.2 m³/s – too low for most generators. This axial flux coreless unit starts generating usable power at just 150 RPM. No cogging, no iron loss, and it’s silent. I’m getting 300-400W continuously, 24/7. My old induction generator would barely light an LED at that speed. Absolutely perfect for low-head hydro.”
