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.

This design needs no foil lining elecyrostatic backing because a potential gradient exists between electrodes on opposite sides of the disks. Discovered by Ben Franklin in the 18th century, electrostatic motors are an all-American invention.
Box, Star City, W. Acrylic cuts and works beautifully.
Jefimenko’s Electrostatic Motors & Heaviside’s Gravitational EM Analogy
Van Wyck and G. Never fly it below clouds or leave it aloft unattended. So the rotor-electrode distance was constantly changing. By continued experimentation Poggendorff learned that he should slant the teeth of the combs to spray charge on the glass at motros angle.
The only essential metal parts are the electrodes and their interconnecting leads. To check for dynamic balance suspend the motor freely with a string, run it at low speed and judge by the wiggle where a counterweight must be added.
And like a magnet, it can be used to build a motor. Energy in this form cannot be drawn on directly for driving ordinary mktors motors.

Instead of sandwiching the electret alternately between pairs of metal plates, Jefimenko employs opposing pairs of adjacent plates [see illustration at rightt].
Effective cylinders can be jefomenko inexpensively out of plastic sewer pipe. You are commenting using your Twitter account.
Electrostatic motors are lighter than electromagnetic motors for the same output power since the motor occupies the entire volume. In a particularly spectacular experiment, Jefimenko turned on a Van de Graaff generator — a device that creates a very-high-voltage field. Once a spot on the rotor assumes a charge, 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.
Twelve stationary thimbles supported by insulating columns were spaced around the disk to graze the rotating metal spheres. Walker, he experimented with electret motors. They are based on the physics of the fair-weather atmosphere that has an abundance of positive electric charges up to an altitude of 20 km. The jefjmenko are one-millimeter strips of kitchen aluminum foil.
The motor can be made self-starting and unidirectional by jdfimenko the knife-edges. Such motors develop mechanical force through the interaction of magnetic fields that are generated with high electric current at low voltage, as Michael Faraday demonstrated in The rotor began to spin.
The adjacent plates are separated by a narrow slot.

The rotor was thus constructed much like a modern flat-plate capacitor. The electrodes set up what physicists call a corona discharge; their sharp edges ionize air molecules that come in contact with jecimenko.
Poggendorff was immensely pleased by the rate at which his machine converted charge into mechanical motion. It is even possible to build a linear corona motor, a design that serves to achieve translational motion. So I take a quick look inside and decide to give an initial report here.
A pair of olwg setscrews could be substituted for the clock bearings. This rotor is sandwiched between four semicircular sectors that are cross-connected electrostxtic see illustration ]. Reviewing the history of electrostatic machines, Jefimenko came across a paper published in by Johann Christoff Poggendorff, a German physicist.
Although Franklin left no drawing of his motor, his description of it in a letter to Peter Collinson, a Fellow of the Royal Society, enabled Jefimenko to reconstruct a working model [see illustration at right].
Jefimenko posits the following Generalized Theory of Gravitation. You are commenting using your Facebook account.
The performance of the motor easily met the design specifications.
