ABSTRACT:
A mechanism for tracking the sun and positioning a solar energy collector, photovoltaic cells being utilized to energize pairs of electric coils rotatably mounted within magnetic rings. When the sun's rays fall upon a bank of photovoltaic cells a pair of coils are energized, setting up electromotive forces in opposition to the force field of the magnetic ring, and rotating the coils and solar collector mounted thereto.
