Aluminum Alloy Coreless Permanent Magnet Generator
Offering efficiency over 92% with Wending Method Y design for optimal performance
GDG series disc-type permanent magnet generator design diagram
Product Overview
The GREEF NEW ENERGY GDG series disc-type permanent magnet generator features a unique stacked disc design where the spindle and rotor are arranged in a disc shape. The stator remains fixed in the central position while the rotor rotates on both sides. Unlike conventional generators, the spindle contains only windings without an iron core.
Both stator and rotor are constructed as flat disc structures utilizing axial air gap magnetic flux, arranged alternately along the axial direction. The short axial length and large diameter enable easy implementation of multi-pole structures, resulting in high power-to-mass ratio, low speed rating, low wind speed starting capability, compact size, low energy consumption, light weight, and high efficiency.
Key Features
  • Low Start Torque Technology: Eliminates hysteresis and gear notch effects with starting torque less than 0.1 N·m
  • High Efficiency Design: Coreless construction reduces mechanical resistance and energy loss
  • Advanced Magnetic System: Rare earth permanent magnets with multiple poles and small air gap for high power density
  • Maintenance-Free Gearless Direct Drive: Brushless design minimizes mechanical wear
  • Higher Reliability and Longevity: Service life up to eight times longer than traditional generators
  • Enhanced Low Wind Speed Utilization: Improved efficiency in varied environmental conditions
  • Exceptional Heat Dissipation: Aluminum alloy frame with specialized internal structure
