Providing Higher Reliability and Enhanced Durability in Harsh Environments
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
