Mô tả sản phẩm
Horizontal and Vertical Shaft Type Coreless Permanent Magnet Generator
GDG series disc-type permanent magnet generator diagram Coreless permanent magnet generator internal structure
Product Overview
The GREEF New Energy GDG series features a disc-type permanent magnet generator that operates without an iron core. This innovative design consists of a spindle and rotor arranged in a disc shape, where the stator is fixed in the center and the rotor rotates on both sides. Notably, the spindle contains only windings and completely lacks an iron core.
Both the stator and rotor are constructed as flat disc structures utilizing axial air gap magnetic flux. They are alternately positioned along the axial direction, which contributes to the generator's unique performance characteristics. Thanks to its short axial length combined with a large diameter, the disc generator can easily accommodate a multi-pole configuration.
This generator design boasts several advantages, including a high power-to-mass ratio, low rated speed, the ability to start at low wind speeds, compact size, reduced energy consumption, lightweight construction, and high efficiency. These features make it an excellent choice for direct-drive vertical axis wind turbines, particularly because of its minimal wind resistance caused by the rotor mounted on the vertical axis.
The GDG series disc-type permanent magnet generators come in two variants: outer rotor and inner rotor types. In the outer rotor design, the shaft does not rotate the casing, and the cable is routed through the center of the shaft. Conversely, in the inner rotor variant, the casing remains stationary while the shaft rotates, with the cable routed outside the casing.
Key Features
  • Low Start Torque Technology: Advanced technology eliminates hysteresis and gear notch effects, resulting in exceptionally low starting torque of less than 0.1 N*m for smooth and efficient startup performance.
  • High Efficiency Design: Coreless design significantly reduces mechanical resistance and energy loss, enhanced by "Precise Coil" technology for improved overall system efficiency.
  • Powerful Magnetic System: Equipped with rare earth permanent magnets featuring multiple poles and small air gap, achieving high power density and substantial output power.
  • Gearless Direct Drive and Maintenance-Free: Brushless configuration with gearless direct drive system ensures reliable operation with minimal maintenance requirements.
  • Enhanced Reliability and Longevity: Special structural design provides larger ratio of power to volume and power to weight, resulting in approximately eight times longer lifespan than traditional generators.
  • Optimal Performance in Low Wind Speeds: Technology allows greater utilization of wind turbines under low wind speed conditions, improving overall energy capture and efficiency.
  • Excellent Heat Dissipation: Aluminum alloy outer frame and specially designed internal structure effectively dissipate heat, contributing to stable operation and durability.
Applications
  • Wind Power Generation: Particularly advantageous for megawatt-class wind turbines, enhancing power output density and overall efficiency in converting wind energy to electrical power.
  • Renewable Energy Systems: Widely applied in solar power generation and other renewable energy systems due to efficient energy conversion and dependable operation.
  • Industrial Applications: Suitable for various industrial applications requiring efficient, lightweight, and dependable power supply, including backup or auxiliary power sources.
  • Custom Solutions: Flexible design allows customization of generator power, operational speed, and output voltage to accommodate specific application requirements.

“I built a small pico hydro system on the creek behind my off-grid cabin. The water head is only 3 meters and flow rate around 0.2 m³/s – too low for most generators. This axial flux coreless unit starts generating usable power at just 150 RPM. No cogging, no iron loss, and it’s silent. I’m getting 300-400W continuously, 24/7. My old induction generator would barely light an LED at that speed. Absolutely perfect for low-head hydro.”
