4 FAQs about How to make a wind turbine generator with Lego

How to install a wind turbine fan?

Align the center of the fan to the center of the wind turbine with a distance of 30 cm (= 12 in.) between them. Choose a suitable power setting on the fan that makes the wind turbine rotate at an adequate speed and where the Energy Meter's display shows more than 2.0 V on the input reading. The fan must have an effect of at least 40 W.

Can a wind turbine generate electricity?

Wind turbines have the ability to convert the wind's kinetic energy into electrical energy. They are used to generate electricity for large utility grids and in isolated locations, such as rural farms. Now build the wind turbine and investigate its ability to generate power. Test the model's functionality. Loosening bushings can reduce friction.

How should students handle wind turbines?

Make sure that students handle them with great care! Ensure that students turn the fan off when changing the number of blades during the activity. The task requires students to investigate the performance of the wind turbine at different settings and to read and record the average voltage (V) and the average power (W) generated.

Can a wind turbine rotate around a horizontal or vertical axis?

Wind turbines can rotate around both horizontal and vertical axis. Horizontal-axis wind turbines (HAWT) are most commonly used. (building instructions booklets 3A and 3B, to page 44, step 1).
