OLEG D. JEFIMENKO West Virginia University. Electrostatic M o t o r s It is also interesting to note that certain types of electrostatic motors were frequently. From Oleg D. Jefimenko, Causality, Electromagnetic Induction, and Gravitation: A Different Approach to the Theory of Electromagnetic and. Electrostatic Motors. Oleg Jefimenko and David K. Walker. Everyone is familiar with the property of elec- tric charges to attract or to repel one another.

The rotor must be balanced both statically and dynamically. Corona rotors can of course also be made in the form of disks. It was invented in by Benjamin Franklin. They have been studied extensively in recent years by Jeflmenko D. The only essential metal parts are the electrodes and their interconnecting leads. Forces that act between the sprayed charges and the knife-edge electrodes impart momentum to the cylinder.
Incidentally, that funny smell is ozone. Jefimenko received his B. The cure took about 3 hours. The charm of these motors lies in the fact that, although they do not accomplish very much, they can run forever. A strip of plastic is placed between sets of knife-edge electrodes jefimfnko to initiate motion in the desired direction. With one grain of gunpowder one cannot achieve so much as with one hundred pounds.
A galvanometer hooked to the plates jumped sharply. The motor is based on an electret made in by Mototaro Eguchi, professor of physics at the Higher Naval College in Tokyo. So I go out on my step and what to my wondering eyes doth appear but the box from Amazon.
The brushes are one-millimeter strips of kitchen aluminum foil. Later, you can make the whole thing permanent by putting a little solvent along the joints.
As the electret moved between the attracting plates, however, the commutator switched the plates to matching polarity. About a yard away he placed a electrostztic corona antenna and connected it to an electrostatic motor. As the thimbles grazed that jar, a spark would again transfer charge, which was of opposite polarity.

The ends of the shaft were ground and polished to 30degree points. Several limitations must first be overcome. We drilled out the old hub and cemented in a new one electtrostatic this time, carefully. This motor consisted of a plastic disk about three millimeters thick and 40 millimeters in diameter supported in the horizontal plane by a slender shaft that turned in jeweled bearings.

The supporting frame was made of quarter-inch Lucite. In his opinion, there is no objective reason for abandoning Newton’s force-field gravitational theory in favor of a metric gravitational theory. The distances between the electrodes and the electrets were needlessly large, so that the forces of attraction and repulsion were needlessly weak.
That deposited a like charge on the thimble, so they repelled each other. Moreover, as I have mentioned, the inner surface of the cylinder should be backed by conducting foil to enhance the corona. By resorting to such stratagems experimenters can devise motors that are extremely light in proportion to their power output. The field was tapped with an antenna consisting of feet of No. Motors of this type are based on the force of mutual attraction between unlike electric charges and the mutual repulsion of like charges.
I made a corona motor with Plexiglas tubing two inches in diameter and one and a half inches long. However, the greatest concentration is near the ground and diminishes with altitude rapidly. Reviewing the history of electrostatic machines, Jefimenko came across a paper published in by Johann Christoff Poggendorff, a German physicist.
This allows for fine adjustment and alignment. The earth is an electrical conductor. Motors based on the slot effect can be designed in a number of forms.

Almost the entire surface of the glass acquired a coating of either positive or negative fixed charges, depending on the polarity of the combs. Flectrostatic about a minute, we clocked some turns with a watch and found it was spinning at rpm.
Twelve stationary thimbles supported by insulating columns were spaced around the disk to graze the rotating metal spheres. When Franklin placed opposite charges on olge top and bottom films and gave the rotor a push, the machine ran just as well as his first design, and for the same reason.
