Coreless Permanent Magnet Generator Overview
3 Phase Coreless Permanent Magnet Generator 0.1kw-20kw IP54 0
A Coreless Permanent Magnet Generator is an advanced generator that utilizes an axial flux design with an ironless core structure to efficiently produce electricity. This innovative design eliminates iron core losses and hysteresis losses commonly found in conventional generators.
Generator Structure
The axial flux ironless core generator consists of:
  • Permanent magnets to create the magnetic field
  • Coils that capture magnetic energy and convert it to electrical energy
  • Protective casing that provides structural support
Operating Principle
The generator operates on electromagnetic induction principles. When permanent magnets move relative to conductor coils, they induce electromotive force (EMF) that is converted into usable electrical energy for powering external devices.
Applications
  • Wind Power Generation: Ideal for megawatt-class wind turbines, increasing output density and efficiency
  • Renewable Energy Systems: Perfect for solar and wind power applications due to high efficiency and reliability
  • Industrial Applications: Provides efficient, lightweight power for backup and auxiliary systems
  • Custom Solutions: Parameters can be customized including power, speed, and output voltage

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.”
