This wind generator uses a brushless DC motor, providing smoother rotation, low noise, and longer service life compared to brushed motors. Ideal for stable and efficient power generation in various DIY and educational projects. Can be driven by wind power or by hand crank (hand drive components not included, compatible with common DIY mechanisms). Suitable for demonstrating both wind energy and manual power generation principles in classrooms or science fairs. Designed specifically for DIY power generation experiments, this unit is perfect for student projects, science experiments, and maker activities. It helps learners understand basic concepts of electricity production, renewable energy, and mechanical-to-electrical energy conversion.
