Low Maintenance Due To No Iron Core Losses Coreless Permanent Magnet Generator Rated Power 300w 100kw Speed 60 550RPM Engineered For Power Supply

Product Description:

The GREEF NEW ENERGY GDG series disc type permanent magnet generator is designed without an iron core. This generator features a unique construction where the spindle and rotor are arranged in a disc-shaped stack. The stator is fixed at the center, while the rotor rotates on both sides of the stator. Notably, the spindle contains only windings and does not include an iron core, distinguishing it from conventional generators.

Both the stator and rotor are constructed as flat discs, utilizing axial air gap magnetic flux. These components are arranged alternately along the axial direction. Thanks to its design, which boasts a short axial length but a large disc diameter, this generator is capable of adopting a multi-pole structure easily. This results in several advantages, such as a high power-to-mass ratio, the ability to operate effectively at low speeds, and quick start-up at low wind speeds.

Additional benefits of the GDG series include a compact size, low energy consumption, lightweight build, and a highly efficient operation. Its compact and lightweight structure makes it especially suitable for direct-drive vertical axis wind turbines. This is because the rotor’s mounting on the vertical axis results in minimal resistance against the wind, optimizing performance.

The GDG series disc type permanent magnet generators come in two variants: the outer rotor and the inner rotor types. In the outer rotor model, the rotor shaft rotates while the casing remains stationary, with the cable exiting through the center of the shaft. Conversely, in the inner rotor variant, the casing does not move, the shaft rotates, and the cable is routed outside the casing. These design differences offer flexibility depending on specific application requirements.

Features:

The technology eliminates hysteresis and gear notch effects, resulting in an exceptionally low starting torque of less than 0.1 N·m. This ensures smooth and efficient startup performance.

By utilizing a coreless design, mechanical resistance and energy loss are significantly reduced. This leads to enhanced efficiency and improved overall performance.

The adoption of “Precise Coil” technology further optimizes the system, ensuring highly accurate electromagnetic control.

The utilization of rare earth permanent magnets with multiple poles and a small air gap results in high power density and substantial output power. This design contributes to superior electromagnetic performance.

Featuring a gearless direct drive and brushless construction, the system requires minimal maintenance, enhancing usability and reducing downtime.

The special structural design offers an increased power-to-volume and power-to-weight ratio. Additionally, it boasts a lifespan up to eight times longer than traditional generators, ensuring long-term dependability.

The technology improves the utilization of wind turbines operating under low wind speed conditions, maximizing energy capture and efficiency.

Thanks to the aluminum alloy outer frame and specialized internal structure, the system achieves excellent heat dissipation, which helps maintain optimal operating temperatures and prolongs component life.

Applications:

Axial flux coreless generators hold significant promise in the field of wind power generation. This is especially true for megawatt-class wind turbines, where such generators can greatly enhance output density, thereby improving the overall efficiency of wind energy conversion.

One of the key advantages is the elimination of the iron core, which decreases iron losses and hysteresis losses. This results in a more efficient generator that effectively maximizes energy production from wind resources.

Beyond wind power, axial flux coreless generators are widely implemented across various renewable energy technologies, including solar and wind power systems. Their ability to convert energy efficiently combined with dependable operation makes them well-suited for sustainable energy generation solutions.

Apart from renewable energy sectors, axial flux coreless generators have versatile uses in numerous industrial applications that demand power supplies that are lightweight, reliable, and efficient. For example, they can serve as backup or auxiliary power sources, providing consistent and stable power support to critical industrial machinery and equipment.

Thanks to their flexible design, axial flux ironless core generators can be tailored to meet specific customer requirements. Various parameters such as generator power, speed, and output voltage can be customized to suit different operational needs and application environments.
