Build Micro-hydro Generator: Prepare the Disks

The generator we are building has two basic parts-the rotor and the stator. The stator is the part that remains stationary and has coils of wire to collect electricity. The rotor is the part that moves. It is equipped with powerful magnets that will induce current of electricity in the coils.

  • Glue the template sheet to the cardboard with white glue. Be sure to spread a thin layer of glue evenly over the entire back of the template .
  • When the glue has dried, use the utility knife to cut the rotor and stator disks from the cardboard sheet. Carefully trim the edges. Also, be careful not to damage the tabletop with the utility knife. Work on a piece of scrap wood or a cutting board.
  • Using an awl or sharp nail, punch a small hole through the rotor disk at its exact center, as shown. Using the utility knife, make a larger (1 cm) hole at the center of the stator disk.
