An electret is a sheet or slab of waxy dielectric material that supports an electric field, much as a permanent magnet carries a magnetic field. Acrylic cuts and works beautifully.
I had corrected the imbalance caused by a lump of cement at one end of the rotor by adding a counterweight on the opposite side at the opposite end of the cylinder.
Corona rotors can of course also be made in the form of disks. As a thimble passed close to a jar, a spark motirs from knob to thimble. He has learned that elevtrostatic performance can be vastly improved by properly shaping the corona-producing electrodes [see illustration at right]. Later, you can make the whole thing permanent by putting a little solvent along the joints.
The entire motor, as pictured here, is a plastic disk Poggendorff used glass and two electrodes. Franklin was incredibly lucky to have jffimenko his celebrated kite experiment. On the end of each spike was a brass thimble. Previous 3, 6, 9. The electret reacts to neighboring charges exactly as though it were a charged electrode, that is, it is physically attracted or repelled depending on the polarity of the neighboring electrode.
Once a spot on the rotor assumes a leectrostatic, it is repelled from the chargin electrode by electrostatic forces, and at the same time is attracted to the other electrode, which has an opposite charge. This is typically totally ignored in the EM community.
When we crank up the electrostatic motor at the top of this page, people always want to know what makes it run. By using this site, you agree to the Terms of Use and Privacy Policy. The solvent flows into the joint and fuses it permanently.
They consume current at the rate of about a millionth of an ampere when they are running at jeffimenko speed. Jefimenko posits the following Generalized Theory of Gravitation. Both surfaces of the disk were coated with a film of gold, except for a boundary around the edge.
We connected the power — and slowly… slowly… the disk began to turn. Jefimenko thinks that earth-field antennas could be built to extract viable amounts of it.
The motor is based on an electret made in by Mototaro Eguchi, professor of physics at the Higher Naval College in Tokyo. With one grain of gunpowder one cannot achieve so much as with one hundred pounds.
The electrodes set up what physicists call a corona discharge; their sharp edges ionize air molecules that come in contact with them. Even they can be contrived of metallic foil backed by any stiff dielectric.
Drill and tap the acrylic and assemble parts with machine screws. The laser beam would ionize the air, creating an invisible conductor through apparently empty space.
The weight in pounds that a helium-filled balloon of leectrostatic shape can lift is roughly equal to a quarter of the cube of its radius in feet.
When the machine operated from a source of from 8, to 13, volts, jefimenkko speeds of up to 12, revolutions per minute were measured. Although a foot vertical antenna electrotatic be handled safely in fair weather, it can pick up a lethal charge during thunderstorms. These remarkable machines are almost unknown today.
The working surface of the rotors should be made of a fairly thin plastic, such as Plexiglas or Mylar. One model consists of a series of disks mounted on a common shaft. Almost the entire surface of the hefimenko acquired a coating of either positive or negative fixed charges, depending on the polarity of the combs. Twelve evenly spaced metal spheres, cemented to the edge of the disk, were connected alternately to the top and bottom gold films.
A serious limitation appears as the altitude of the antenna exceeds about meters. Unshielded electrets attract neutralizing ions from the air and lose their charge within hours or days. Cut edges can be sanded so they have a white, frosted appearance that, in contrast with clear surfaces, gives your finished motor a sparkling, jewel-like appearance.
The adjacent plates are separated by a narrow slot. Would you believe an electric motor made almost entirely of plastic? The devices that you see here are corona-discharge motors. The cure took about 3 hours. Jefimenko has demonstrated a similar motor that was designed to turn at a rate of about 60 revolutions per minute and develop a millionth of a horsepower on a foot antenna having a small polonium probe at its upper end.
I made a corona motor with Plexiglas tubing two inches in diameter and one and a half inches long. Corona motors require no brushes or commutators.

Jefimenko has worked electroztatic the development of the theory of electromagnetic retardation and relativity. What can I say? Same things goes for the E field created by Faraday induction.
So they must be built with watch-making precision. Electret Scientific, Star City, The sharp-pointed or knife-edge electrodes create a corona, which ionizes or charges the air particles floating by.
Jefimenko’s Electrostatic Motors & Heaviside’s Gravitational EM Analogy
Motors of this type are based on the force of mutual attraction between unlike electric charges and the mutual repulsion of like charges.

He showed us motors that run on the voltage developed when you hold them in your hands and scuff across a carpet, and other heavier, more powerful ones that could do real work.
