Magnetically Levitating Solar Powered Mendocino Motor

Get yourself one of the coolest solar powered toys around! This Mendocino motor can be an excellent gift, useful educational tool, or an eye-catching show-piece. 

The rotor block has two sets of windings and a solar cell attached to each side. The shaft is positioned horizontally and has a magnet at each end. The magnets on the shaft provide levitation by repelling magnets in a base under the motor. 

When light strikes one of the solar cells, it generates an electric current thus energizing one of the rotor windings. This produces a magnetic field, which interacts with the field of the magnet under the rotor. This interaction causes the rotor to turn. As the rotor rotates, the next solar cell moves into the light and energizes the second winding, creating a current in an opposite direction to the first, thus maintaining the rotation. This process repeats as the motor spins.
