Περιγραφή του προϊόντος
3 Phase Coreless Permanent Magnet Generator
GDG Series Coreless Permanent Magnet Generator
Product Overview
The GREEF NEW ENERGY GDG series features a disc-type permanent magnet generator that operates without an iron core. This innovative design consists of a spindle and rotor arranged in a disc shape, where the stator is fixed at the center, and the rotor rotates on both sides. Notably, the spindle contains only windings and lacks an iron core, enhancing performance and reducing weight.
Both the stator and rotor are constructed as flat disc structures that utilize axial air gap magnetic flux. They are alternately positioned along the axial direction, which contributes to the generator's compact and efficient design. Due to its short axial length and large diameter, the disc generator easily supports a multi-pole configuration, resulting in a high power-to-mass ratio.
The GDG series boasts several advantages including a low speed rating, the ability to start at low wind speeds, small size, reduced energy consumption, light weight, a compact structure, and high efficiency. These characteristics make it an ideal choice 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
  • High Efficiency: Very low mechanical resistance and minimal energy loss without core
  • Advanced Technology: "Precise Coil" technology with rare earth permanent magnets and multi-pole design
  • Maintenance-Free Design: Gearless direct drive and brushless construction
  • Enhanced Reliability: 8 times longer lifespan than traditional generators
  • Optimized Low Wind Performance: Better utilization in low wind speed conditions
  • Excellent Heat Dissipation: Aluminum alloy outer frame with specialized internal structure
Applications
  • Wind Power Generation: Ideal for megawatt-class wind turbines with enhanced output density
  • Renewable Energy Systems: Solar and wind power setups with efficient energy conversion
  • Industrial Power Sources: Backup or auxiliary power units for various industrial equipment
  • Customized Solutions: Tailored parameters for specific application requirements

“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.”
