GDG series disc-type permanent magnet generator overview Generator internal structure and components Generator installation and application
GDG Series Disc-Type Permanent Magnet Generator
Product Overview
The GREEF New Energy GDG series disc-type permanent magnet generator features an innovative iron-core-free design. This unique generator employs a spindle and rotor arranged in a disc configuration, with the stator fixed at the center and the rotor rotating on both sides. The spindle contains only windings without an iron core, significantly enhancing generator performance.
Both stator and rotor utilize a flat disc structure with axial air gap magnetic flux, positioned alternately along the axial direction for a compact form factor. The disc generator combines a short axial length with a large diameter, making it ideal for multi-pole configurations.
The GDG series offers exceptional power-to-mass ratio, low-speed operation, and efficient startup even at low wind speeds. Its compact, lightweight design results in low energy consumption and streamlined structure. High efficiency and minimal wind resistance make it perfect for direct-drive vertical axis wind turbines.
Available in two configurations: outer rotor (stationary casing with center cable routing) and inner rotor (rotating shaft with external cable exit).
Key Features
  • Low Start Torque Technology: Minimal startup resistance with starting torque less than 0.1 N*m
  • High Efficiency: Core-free design reduces mechanical resistance and energy loss
  • Advanced Magnet Technology: Rare earth permanent magnets with multiple poles and small air gap
  • Gearless Direct Drive: Brushless design eliminates maintenance requirements
  • Enhanced Reliability: Up to 8x longer lifespan than traditional generators
  • Optimized for Low Wind Speed: Higher utilization in low wind environments
  • Excellent Heat Dissipation: Aluminum alloy frame with specialized internal structure
Applications
  • Wind Power Generation: Ideal for megawatt-class wind turbines with enhanced output density
  • Renewable Energy: Solar and wind power generation systems
  • Industrial Applications: Backup and auxiliary power for critical equipment
  • Customized Solutions: Tailored power, speed, and voltage parameters
