Product Description

Product Description:

Definition of Axial Flux Ironless Core Generator

An axial flux ironless core generator is a unique type of generator that utilizes an axial flux design and an ironless core structure to generate electricity. Unlike conventional generators that suffer from iron core losses and hysteresis losses, the axial flux ironless core generator is designed to avoid these inefficiencies.

Structure

The axial flux ironless core generator primarily consists of permanent magnets, coils, and casing. The permanent magnets are responsible for generating the magnetic field, while the coils are responsible for capturing the energy in the magnetic field and converting it into electrical energy. The casing provides the internal structure of the generator with a sturdy support and prevents any potential damage to the generator.

The Principle of Operation

The principle of operation of an axial flux coreless generator is based on the concept of electromagnetic induction. As a magnetic field that is generated by a permanent magnet moves relative to a conductor in a coil, an induced electromotive force gets generated in the conductor. This electromotive force can further be converted into electrical energy, thus providing power for external devices.

 

Applications:

Wind Power Generation

Axial flux coreless generators have shown significant potential in wind power generation, particularly in megawatt-class wind turbines. These generators can increase the output density and improve the overall efficiency of wind power generation. Furthermore, the absence of an iron core reduces iron losses and hysteresis losses, which further improves the efficiency of the generator.

Renewable Energy

Axial flux coreless generators are also widely used in various renewable energy applications, such as solar and wind power generation systems. These generators are favored due to their capability to efficiently convert energy and reliable operation. Hence, they are an ideal choice for renewable energy generation systems.

Other Industrial Applications

Axial flux coreless generators can also be used in various industrial applications that require efficient, lightweight, and reliable power supply. For example, these generators can be utilized as a backup power source or auxiliary power supply to provide stable power support to industrial equipment.

Customized Applications

The axial flux ironless core generator has a flexible structure and can be customized according to specific customer requirements. Parameters such as generator power, speed, and output voltage can be adjusted to meet the different application scenario needs.

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.

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!
