Manufactured by industry-leading experts in wind energy technology, this turbine delivers exceptional performance with a maximum power coefficient of 46%, ensuring efficient conversion of wind energy to electricity across a wide range of wind conditions. The elimination of gearbox components through its permanent magnet direct drive system reduces maintenance requirements while increasing reliability and operational lifespan. Optimized for wind speeds between 2.5m/s and 20m/s, the turbine generates up to 180,000 kWh annually in optimal conditions, making it ideal for commercial, industrial, and community-scale renewable energy initiatives seeking both performance and durability.
The turbine utilizes a high-efficiency permanent magnet generator directly coupled to the rotor, eliminating gearbox losses and reducing maintenance requirements by up to 50% compared to gear-driven systems . This design achieves a maximum conversion efficiency of 96.5% from mechanical to electrical energy, significantly reducing energy loss during power generation.
Equipped with an advanced yaw control system featuring dual hydraulic actuators and wind direction sensors with ±1° accuracy, the turbine continuously optimizes rotor alignment with wind direction. This precision alignment increases energy capture by up to 8% compared to standard yaw systems, particularly in variable wind conditions.
The 9m diameter rotor features three glass fiber reinforced polymer blades with an optimized airfoil design that achieves a maximum power coefficient of 46%. The blades incorporate stall control mechanisms to regulate power output during high wind conditions, ensuring stable performance across the turbine's operating range.
Built to withstand harsh environmental conditions, the turbine features a hot-dip galvanized steel tower, weather-sealed nacelle (IP65 rating), and corrosion-resistant components that ensure reliable operation in temperatures ranging from -35°C to +55°C . The robust design supports a 20-year service life with minimal maintenance requirements.
Cities and local governments deploy the turbine to power public facilities including water treatment plants, administrative buildings, and transportation hubs, reducing municipal energy costs while meeting climate action goals.
University campuses, corporate parks, and research facilities utilize the turbine as a centerpiece of their renewable energy strategies, generating significant portions of their electricity needs while serving as educational demonstrations of sustainable technology.
Energy developers deploy clusters of turbines in medium-scale wind farms, leveraging the high efficiency and reliability of the direct drive system to maximize project returns while qualifying for renewable energy incentives.
Mining camps, forestry operations, and offshore platforms utilize the turbine as part of hybrid energy systems, reducing reliance on diesel generators, lowering operational costs, and minimizing environmental impact in isolated locations.
By eliminating the gearbox, the direct drive system reduces mechanical losses by up to 15% while significantly decreasing maintenance requirements and potential points of failure. The permanent magnet generator provides higher efficiency at partial loads, improving overall energy production in variable wind conditions. This design also operates more quietly than gear-driven alternatives.
Our precision yaw system uses wind direction sensors to detect wind shifts and activates hydraulic actuators to rotate the nacelle, maintaining optimal rotor alignment within ±1° of the wind direction. This continuous adjustment maximizes energy capture, particularly in locations with variable wind patterns, increasing annual energy production by up to 8% compared to fixed or less precise yaw systems.
The turbine is certified to EU CE standards under Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. It also meets IEC 61400-1 and IEC 61400-22 standards for wind turbine performance and safety, as well as ISO 9001 quality management and ISO 14001 environmental management standards, ensuring global market acceptance.
The turbine requires biannual inspections and annual preventive maintenance, with major component inspections at 5-year intervals. The direct drive system eliminates gearbox maintenance, reducing service costs significantly. With proper maintenance, the turbine is designed for a 20-year service life, with major components rated for 120,000+ hours of operation.
