I would like to build a rotating platter that is powered by solar cells surface-mounted on the vertical sides of the platter. The solar cells will completely wrap around the diameter of each platter. The solar cells will charge a capacitor and discharge circuit similar to that of a disposable camera. The idea is to build a charge via solar that when fed to a motor, will make the platter rotate in whatever (preferably small) increment the charge and motor HP are capable. The solar cells are up for design spec but I have found some 1/8" units that produce .475v ea. Given that size and output, I figure that if spaced out .25" apart around the side of the platter, a 3" diameter platter or "coaster" could hold 12 cells for a total, full output of 5.7v. I now need to figure out how to match the work load of the rotating mass to the solar and electrical needs to make the load rotate as described above. I am NOT looking to provide steady rotation. A stepped rotation is preferred and seems to be more practical. I am by trade an audio engineer and not an electrician or physicist so forgive me if my ideas and directions are off or grossly out of line. I simply do not have the knowledge (yet) to make sense of this on my own. Any guidance would be greatly appreciated. Justin
I would like to find a formula or formulas that allow me to scale up the idea to rotate various loads ranging from .5lb up to 30lbs. |
