KidWind Wind Turbine Hub

This 12-hole crimping hub, made from recycled plastic, allows you to turn any DC generator into a wind turbine. The hub will press fit onto the shaft of many small DC generators; just attach your own blades and begin experimenting with wind power! The hub is designed to allow you to change blade angles and/or interchange blade sets quickly and easily. An improved stainless-steel insert can take a beating in your classroom year after year without failing!

You Can:

• Convert DC motor into a wind turbine by fitting this onto a 2 mm driveshaft
• Experiment with up to 12 blades
• Quickly change blade designs and/or pitch angle
