The GREEF NEW ENERGY GDG series disc-type permanent magnet generator features a unique coreless design with spindle and rotor assembled in a disc shape. The stator is fixed at the center while the rotor rotates on both sides, utilizing axial air gap magnetic flux for compact and efficient operation.
With its short axial length and large diameter, this generator easily accommodates multi-pole structures, offering high power-to-mass ratio, low-speed operation capability, and low wind speed starting. Available in both outer rotor and inner rotor variants to suit various application requirements.
Key Features
Low Start Torque: Less than 0.1 N*m, eliminating hysteresis and gear notch effects
High Efficiency: Coreless design reduces mechanical resistance and energy loss
Advanced Magnetic Design: Rare earth permanent magnets with multiple poles and small air gap
Gearless Direct Drive: Brushless and maintenance-free operation
Enhanced Reliability: Eight times longer lifespan than traditional generators
Superior Heat Dissipation: Aluminum alloy frame with unique internal structure
