Low Maintenance Due To No Iron Core Losses Motor Featuring Low Start Torque Rated Power 300w 100kw Suitable For HVAC Systems

Product Description:

The GREEF NEW ENERGY GDG series features a disc-type permanent magnet generator that operates without an iron core. This innovative design integrates the spindle and rotor stacked in a disc-shaped configuration. The stator is fixed at the center, while the rotor spins on both sides. Notably, the spindle contains only windings and lacks an iron core, which contributes to its lightweight build and efficiency.

Both the stator and rotor are constructed as flat disc structures utilizing axial air gap magnetic flux. They are alternately arranged along the axial direction, which optimizes the magnetic interaction between the components. Due to the generator's short axial length combined with a large diameter, it is well-suited for creating a multi-pole structure. This results in a high power-to-mass ratio and allows for low-speed operation with a reduced wind speed startup threshold.

The GDG series disc generators are compact, lightweight, and energy-efficient. Their design boasts a small footprint, low energy consumption, and a high efficiency rate. These characteristics make the generators especially desirable for direct-drive vertical axis wind turbines, as the rotor creates minimal resistance to wind when mounted on a vertical axis.

Within the GDG series, there are two primary types available: the outer rotor and the inner rotor. In the outer rotor type, the rotor spins while the casing remains stationary, and the cable exits through the center of the shaft. Conversely, the inner rotor type features a stationary casing with a rotating shaft, and the cable is routed outside the casing.

Features:

The technology ensures an exceptionally low starting torque, less than 0.1 N·m, by eliminating the effects of hysteresis and gear notches. This advancement allows for smoother and more efficient startup performance.

By removing the core, the device experiences very low mechanical resistance, significantly reducing energy loss. The use of “Precise Coil” technology further enhances efficiency in energy conversion.

Featuring rare earth permanent magnets, multi-pole configurations, and a small air gap, this product boasts high power density and delivers substantial output power for its size.

The gearless direct drive design coupled with brushless construction ensures reliable, maintenance-free operation, reducing downtime and operational costs.

A specialized structural design results in greater power-to-volume and power-to-weight ratios, leading to an extended lifespan that is eight times longer compared to traditional generators.

This technology significantly improves the utilization efficiency of wind turbines, especially in environments with low wind speeds, ensuring more consistent energy production.

Constructed with an aluminum alloy outer frame and a unique internal structure, the device provides superior heat dissipation, maintaining optimal performance and durability.

Applications:

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

One key advantage of these generators is the absence of an iron core, which effectively reduces iron losses and hysteresis losses. As a result, the generator operates with higher efficiency compared to traditional designs.

Beyond wind power, axial flux coreless generators are widely utilized in various renewable energy systems, including solar and wind energy applications. Their ability to convert energy efficiently combined with reliable performance makes them an excellent choice for renewable energy generation.

Aside from renewable energy, these generators find applications in numerous industrial sectors that demand power supplies which are lightweight, dependable, and efficient. For instance, they can serve as backup or auxiliary power sources, providing stable support to critical industrial equipment.

The axial flux coreless generator offers a flexible design that can be tailored to meet specific customer requirements. Parameters such as power output, rotational speed, and voltage levels can be adjusted accordingly to fit diverse operational scenarios.
