Horizontal And Vertical Shaft Type Coreless Permanent Magnet Generator
Product Overview
The GREEF NEW ENERGY GDG series disc-type permanent magnet generator features an innovative coreless design where both spindle and rotor are arranged in a disc shape with the stator positioned centrally. The rotor rotates on both sides of the stator, while 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, alternately arranged along the axial direction. The generator's short axial length combined with large diameter enables a multi-pole structure, delivering high power-to-mass ratio and efficient low-speed operation.
Available in outer rotor and inner rotor variants, the GDG series offers compact size, low energy consumption, lightweight construction, and 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
High Efficiency: Coreless design reduces mechanical resistance and energy loss with "Precise Coil" technology
Advanced Magnetic Design: Rare earth permanent magnets with multiple poles and small air gap for high power density
Gearless Direct Drive: Brushless, maintenance-free system with increased reliability
Higher Reliability and Longevity: Special structural design provides eight times longer lifespan than traditional generators
Wind Power Generation: Ideal for megawatt-class wind turbines with increased output power density and reduced iron-related losses
Renewable Energy: Extensive use in solar power and other sustainable energy systems
Industrial Applications: Backup and auxiliary power supplies for critical machinery and equipment
Customized Applications: Flexible structure allows tailoring of power output, speed, and voltage parameters
