Productbeschrijving
Frequency 50/60Hz Coreless Wire Coil Equipment
Providing Higher Reliability and Enhanced Durability in Harsh Environments
GDG Series Disc Type Permanent Magnet Generator external view Generator internal disc structure and components Coreless wire coil stator close-up Permanent magnet rotor assembly
Product Overview
The GDG series disc type permanent magnet generator by GREEF New Energy features an innovative coreless design where the spindle and rotor are arranged in a disc shape. The stator is fixed centrally while the rotor rotates on both sides, utilizing axial air gap magnetic flux technology.
This unique design results in a high power-to-mass ratio, low rated speed, and efficient startup at low wind speeds. The compact size, light weight, and reduced energy consumption contribute to its overall high efficiency, making it ideal for direct-drive vertical axis wind turbines.
Key Features
  • Low Start Torque Technology
    Eliminates hysteresis and gear notch effects with starting torque less than 0.1 N*m for smoother startup performance.
  • High Efficiency
    Coreless design minimizes mechanical resistance and energy losses, delivering superior energy conversion efficiency.
  • Advanced Magnetic Design
    Rare earth permanent magnets with multiple poles and small air gap enable large output power in compact form.
  • Gearless Direct Drive
    Brushless design ensures maintenance-free operation with reduced mechanical complexity.
  • Higher Reliability
    Special structural design provides eight times longer lifespan than traditional generators.
  • Optimized for Low Wind Speeds
    Maximizes energy harvesting in low wind speed conditions.
  • Excellent Heat Dissipation
    Aluminum alloy frame and specialized internal structure maintain optimal performance.
Applications
  • Wind Power Generation
    Ideal for megawatt-class wind turbines with enhanced output density and reduced iron losses.
  • Renewable Energy Systems
    Suitable for solar power and other renewable energy platforms with reliable operational characteristics.
  • Industrial Applications
    Backup and auxiliary power supplies for critical industrial equipment requiring lightweight, efficient power sources.
  • Customized Solutions
    Flexible design allows customization of power output, rotational speed, and voltage levels.

Het is nuttig. (4)
“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.”
