CF
11 – 11.1m Rotor Overview

CF11-11-SummaryThe CF11 is a 11kW radial generator wind turbine with active blade pitch and an active yaw. The radial generator offers better power performance and an increased AEP on our competitors.  The Radial generator has a high magnetic flux. The magnets have multiple coatings and are sealed in a glass fibre/epoxy coating. This means that a magnet can never be dislodged and corrosion is practically impossible

The active blades pitch protects the turbine and optimises aerodynamic performance during the fiercest of operating conditions. . In extreme winds, the blades can be feathered 90 degrees out of the wind which greatly reduces the wind load on the blades and turbine.  The blade pitching mechanism also serves as a very effective emergency brake.

Active yaw control -a purpose built microprocessor monitors the wind vane and the anemometeron all C&F turbines. This directs the yaw or slew motor, allowing the turbine to be optimally aligned to the wind. Not only does this improve efficiency but it reduces fatigue loading on the turbine.

Remote monitoring through our in-house designed GSM controller ensures your turbine is always performing to its optimum, giving you piece of mind that your investment is continuously working for you.

Our unique hydraulic tilt lift system allows for easy access for maintenance and service.
