Product Specification
3 Phase Coreless Permanent Magnet Generator Featuring Aluminum Alloy Shell and Inner Rotor Structure Suitable for Renewable Energy
Product Overview
The GREEF NEW ENERGY GDG series features a disc-type permanent magnet generator that operates without an iron core. In this innovative design, the spindle and rotor are arranged in a disc shape, with the stator fixed at the center and the rotor rotating on both sides. The spindle contains only windings and excludes any iron core components.
Both stator and rotor utilize flat disc configurations with axial air gap magnetic flux, alternately positioned along the axial direction to create an efficient magnetic circuit. The generator's short axial length combined with large diameter enables practical multi-pole construction, delivering high power-to-weight ratio and effective low-speed operation.
Key Features
- Low Start Torque Technology: Eliminates hysteresis and gear notches for extremely low starting torque (less than 0.1 N*m), ensuring smooth and efficient operation
- High Efficiency: Core elimination reduces mechanical resistance and energy loss, enhanced by "Precise Coil" technology
- Advanced Magnetic Design: Utilizes rare earth permanent magnets with multiple poles and small air gap for high power density and substantial output power
- Gearless Direct Drive: Brushless maintenance-free mechanism provides hassle-free, durable long-term operation
- Higher Reliability: Special structural design improves power-to-volume and power-to-weight ratios with eight times longer lifespan than traditional generators
- Optimized for Low Wind Speeds: Enables higher wind turbine utilization in low wind speed conditions, maximizing energy capture
- Excellent Heat Dissipation: Aluminum alloy outer frame with specially designed internal structure maintains optimal operating temperatures
Applications
- Wind Power Generation: Ideal for megawatt-class wind turbines, enhancing output density and overall efficiency through elimination of iron losses and hysteresis losses
- Renewable Energy Systems: Suitable for solar power setups and various renewable energy technologies with efficient energy conversion and dependable performance
- Industrial Applications: Provides reliable backup or auxiliary power sources for industrial equipment with lightweight design and stable power delivery
- Customized Solutions: Highly adaptable structure allows customization of power output, rotational speed, and voltage parameters for specialized scenarios
