2015-05-12 (Tu) Wind Generator Test Base

Long rubber O-rings were purchased to act as the belt between the pulley included with the electric motor and the printed pulley previously designed. Five plastic rectangles were cut and and drilled to attach to the generator enclosures. The pieces were attached to PVC Ts. Ts were used because they have a surface where a flat plane can be attached. Two screws were put into each plastic piece into the PVC Ts.

Originally an elastic strip was going to be cut to length and made into a belt but the thin rubber O-ring provided a simple solution. Since a custom belt wasn't going to be used the distance between the pulleys was very important. A PVC pipe was repeatedly shortened to find a usable size which kept some tension on the O-ring. When the generator and pulley were mounted a spin test was done to ensure the O-ring would ride on the pulleys well and it did. The rest of the fixture was assembled by cutting lengths of schedule 40 3/4" PVC to act as extension arms and stabilizing arms. The angled PVC adapter and the coupler will be the mounting points for the stations.
