Solar Cell Motor

Mendocino Motor: each face of solar cell is connected to coil of copper wire under the opposing solar cell. When the rotor is lit from above the top solar cell provides electric current to the coil in the bottom position which becomes a temporary electromagnet that pushes against the permanent magnet in the base propelling the rotor to rotate. As the rotor turns coil in the bottom is likewise energized by the solar cell in the top position- one can say the light commutates this motor. 2D magnetic levitation is provided by permanent magnets where an acrylic plate constrains the third dimension, and makes for a nice bearing surface for minimal friction. Invented in the 1960s by Daryl Chaplin of Bell Labs and popularized by Larry Springs of Mendocino CA ➡️ Follow the link in my profile for more info and where to buy this and other amazing items featured here on @physicsfun #solarmotor #solarcell #mendocinomotor #maglev #magnetic #magneticfield #equilibrium #physics #physicstoy #dipole #rotation #spin #desktoy #levitation #science #scienceisawesome
