This TeacherGeek Mini Hub is designed to slide directly on a motor shaft. It is comprised of two parts that are held together with a single screw. This allows you to secure 2, 3 or 6 turbine blades. When the hub is mounted on the motor shaft and driven by the wind, electricity is generated.

Extra motors used in our popular Catch the Bug Activity.
