Product type
Direct drive wind turbines are a type of wind energy technology that utilize a direct connection between the rotor and the generator, eliminating the need for a gearbox. This design improves efficiency and reduces maintenance requirements, as there are fewer moving parts involved. Typically made from durable materials such as steel and composite materials, these turbines are designed to harness wind energy effectively in various wind conditions.
| Rated power output | 100 kW to 10 MW |
| Rotor diameter | 20 m to 150 m |
| Cut-in wind speed | 3 m/s to 4 m/s |
| Cut-out wind speed | 25 m/s to 30 m/s |
| Efficiency | Up to 50% under optimal conditions |
| Operating temperature range | -30°C to 40°C |
When selecting a direct drive wind turbine, consider the rated power output needed for your application and the specific wind conditions of your installation site. It's important to specify the rotor diameter and efficiency requirements, as these factors will influence overall performance. Additionally, inquire about certifications and compliance with local regulations, as well as the availability of maintenance services. Quantities may vary based on project scale, so be prepared to discuss your project needs in detail.
