Vertically Fixed Coreless Permanent Magnet Generator Aluminium Body Copper Wire NdFeB Material Offering Low Maintenance Due To No Iron Core Losses

Product Description:

The GREEF NEW ENERGY GDG series disc-type permanent magnet generator is designed without an iron core. This innovative generator features a spindle and rotor arranged in a disc shape, where the stator is fixed at the center and the rotor rotates on both sides. Notably, the spindle contains only windings without any iron core material.

Both the stator and rotor are structured as flat discs that utilize axial air gap magnetic flux. They are alternately positioned along the axial direction, which allows for a unique configuration. Due to the generator’s short axial length combined with a large diameter, it efficiently supports a multi-pole design, resulting in a high power-to-mass ratio.

This design enables a low-speed operation, ease of starting at low wind speeds, and compact dimensions. Additionally, the generator boasts low energy consumption, lightweight construction, and a compact structure, leading to high operational efficiency. These characteristics make it an ideal choice for direct-drive vertical axis wind turbines, especially because the rotor imposes minimal wind resistance.

The GDG series disc-type permanent magnet generators come in two variations: outer rotor and inner rotor types. In the outer rotor design, the shaft remains stationary while the casing rotates, and the cable is routed through the center of the shaft. Conversely, the inner rotor type features a rotating shaft with a stationary casing, and the cable is routed outside the casing.

Features:

Our advanced design eliminates hysteresis and gear notch effects, resulting in an exceptionally low starting torque of less than 0.1 N·m. This feature ensures smooth and efficient operation right from the start.

By eliminating the core, mechanical resistance and energy loss are significantly reduced. This coreless design contributes to higher overall efficiency, enhancing the performance of the system.

Utilizing rare earth permanent magnets with multiple poles and a small air gap, our technology achieves high power density and large output power. This precise coil technology ensures optimal electromagnetic performance.

The gearless direct drive system is brushless and requires no maintenance. This design not only reduces mechanical complexity but also improves reliability and lifespan.

A special structural design enables a larger power-to-volume and power-to-weight ratio. This results in a product life eight times longer than traditional generators, ensuring dependable and sustained operation.

Our technology allows wind turbines to operate more effectively even in low wind conditions, maximizing energy capture and utilization.

The outer frame made from aluminum alloy combined with a specialized internal structure provides excellent heat dissipation. This helps maintain optimal operating temperatures and prolongs the device's lifespan.
