3 Phase AC Permanent Magnet Generator With Higher Reliability And IP 54 Portection Grade 4

Product Description:

An axial flux ironless core generator is a type of generator that utilizes an axial flux design and an ironless core structure to generate electrical energy. Unlike conventional generators, it avoids significant losses due to iron core losses and hysteresis losses.

Permanent magnets, coils, and casing are the key components of this type of generator. The permanent magnets play a vital role in generating a magnetic field, while the coils are responsible for converting the energy from the magnetic field into electrical energy. The casing provides structural support to the generator and also protects its components from damage.

The principle of electromagnetic induction serves as the basis for the operation of axial flux coreless generators. When the magnetic field created by a permanent magnet moves relative to a conductor within a coil, an electromotive force is induced in the conductor. This electromotive force can be used to generate electrical energy, which can then be used to power external devices.

 

Applications:

Wind power generation is one area where axial flux coreless generators have shown great potential. Megawatt-class wind turbines can benefit greatly from these generators as they increase the output density, leading to a more efficient power generation process.

The absence of an iron core in these generators results in a reduction in iron losses and hysteresis losses, thereby making the generator more efficient. This makes axial flux coreless generators ideal for usage in renewable energy applications such as solar and wind power generation systems.

Besides renewable energy, these generators can also be used in a variety of other industrial applications. They are efficient, lightweight, and provide a reliable power supply and can be used as backup or auxiliary power sources to provide stable power support to industrial equipment.

Another advantage of axial flux ironless core generators is that they can be customized to meet specific customer needs. Parameters such as generator power, speed, and output voltage can be adjusted according to the needs of different applications, making them an even more versatile choice.

 

Customization:

Our generators have a start torque of less than 1 N/M and a protection grade of IP 54, ensuring durability and reliability. With large output power, our generators are perfect for a variety of applications.

We offer a minimum order quantity of 1 set and negotiable prices, with packaging details of foam+plywooden case. Our delivery time is 25 working days and we accept payment terms of T/T, Western Union, MoneyGram, and L/C. We have a strong supply ability to meet your needs.

Our Coreless Permanent Magnet Generator is also CE certified, ensuring quality and safety. Contact us today to customize your generator to your exact specifications.

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.”
