Clean, renewable energy
from the sun
February, 1991, Doug Doe of Mendocino California loaned Larry Spring a
little solar motor that Larry placed in the window of his
electromagnetic experimentation shop on the Mendocino Coast.
Bob Blick a local electronic wizard and teacher had constructed a
simple solar motor with Doug Doe some years earlier, using a solar cell
mounted on a coil wound around a spool from the center of a roll of
A few months later Larry constructed his first solar motor. This unique
motor is self starting as the solar cells are mounted right on the
armature of the motor. On July 4, 1994, Larry suspended the armature on
magnetic bearings creating the Larry Spring's Magnetic
Levitation Mendocino Brushless Solar Motor
To Larry's knowledge this may be the first of its kind. If you have
positive documentation of an earlier model, we would be happy to
review, and give proper credit. firstname.lastname@example.org
Photons (Magnespheres in the visible range)
energize the solar cells with pure magnetic energy which causes
electron flow (electrical current)
The electrical current (or energy)
travels via electrons through the wire wrapped around the armature.
The expanding magnetic field of the wire is
rejected by the permanent magnetic field of the drive magnet.
This “kicking out” action causes the armature to rotate above the
magnetic field of the ceramic magnets. (A DC magnesphere, can range
in size from near 0 – to potential infinity)
Larry Spring also uses the Spring Demonstrator
to show how simple motors work.
