Wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common. They can also include blades or be bladeless. Household-size vertical designs produce less power and are less common. Large three-bladed horizontal-axis wind turbines (HAWT) with the blades upwi

The ratio between the blade speed and the wind speed is called tip-speed ratio. High efficiency 3-blade-turbines have tip speed/wind speed ratios of 6 to 7. Wind turbines spin at varying speeds (a consequence of their generator design). Use of aluminum and composite materials has contributed to low rotational inertia, which means that newer wind turbines can accelerate quickly if the winds pic

Most turbines have three blades which are made mostly of fiberglass. Turbine blades vary in size, but a typical modern land-based wind turbine has blades of over 170 feet (52 meters). The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field.
A modern wind turbine blade is designed in a shape that is similar to the wings of an airplane. Airplane wings are very aerodynamic, able to let wind pass by at very high speeds. Wind turbine blades have been designed in many shapes and styles throughout the evolution of wind energy technology.
Wind Blade: 23.8 inch in length, the longer blade will generate more power. The blades are made of Nylon carbon fiber which special on waterproof, corrosion resistant, lightweight. ★Wind Generator: Three-phase permanent magnet synchronous motor. Efficient and compact ac generator with high performance NdFeB permanent magnet.
In this case, though, the lift creates a rotational force and causes the blades to spin in hopes to create enough rotational force to power a turbine generator. The wind turbine blade design will vary between manufacturers and types of turbines, however the theory of “lift” is consistent with every wind turbine blade design.
This chapter presents an overview of wind turbine generator technologies and compares their advantages and drawbacks used for wind energy utilization. Traditionally, DC machines, synchronous machines and squirrel-cage induction machines have been used for small scale power generation.
Wind Generator: Three-phase permanent magnet synchronous motor. Efficient and compact ac generator with high performance NdFeB permanent magnet. ★Rotating Aluminum Alloy Body: With yaw adjustment system, the wind direction position is automatically read and the rotor position is adjusted to capture the maximum wind energy.
