Lenz2 Helical Turbine XL

thingiverse

This is a large-scale turbine version that uses 32cm diameter blades and a 1 meter M10/M16 threaded rod for the shaft. The rotating assembly consists of nine blades, twelve arms, four center hubs, and two hub tops for the bearings. The stator mount is mounted at 70cm from the top using a nut, and an aluminum tube is inserted into the surface mount, which is then clamped to a small wooden plate for stability. The M10/M16 threaded rod is threaded with Axle guides, and one nut is placed on the bottom while another with a washer is placed on top. The rotating assembly is then slid over the threaded rod and secured with a Nyloc nut at the top. An end cap is also added to keep rain out. The turbine is designed to drive a small axial flux turbine for further development.
