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 performance of the motor easily met the design specifications. Static balance was achieved by experimentally adding small bits of adhesive tape to the motofs surface of the aluminum foil that lines the cylinder until the rotor remained stationary at all positions to which it was set by hand.
Jefimenko discovered that when sharp-pointed antennas are designed for a sufficient length to obtain at least volts of threshold energy, the fair-weather current density available is about a picoampere per square meter.
Jefimenko puts on an impressive demonstration. The charm of these motors lies in the fact that, although they do not accomplish very much, they can run forever. He received his M. The center of the shaft was supported transversely by an axle. He received his Ph. It is conceivable that such motors could replace the complex installations now needed for converting the high-voltage d.
Such antennas produce about elecrrostatic microampere of current.
The conducting surfaces of the commutator consist of dried India ink. The devices that you see here are corona-discharge motors. An antenna consisting of a single point at the top of a foot wire could be expected to deliver about a microampere eleftrostatic 2, volts; the rate is equivalent to.
Adhesive tape makes a convenient counterweight material because it can be both applied and shifted easily. The force of repulsion between the like charges imparted momentum to the wheel. He received his Ph. Elecgrostatic to Griffiths, Jefimenko currently submits one or two papers a week to American journals, gets denied, then publishes them in Europe where review is apparently not as stringent.
The upper end of the tinsel was hoisted aloft olsg a cluster of three weather balloons. Instead of sandwiching the electret alternately between pairs of metal plates, Jefimenko employs opposing pairs of adjacent plates [see illustration at rightt].

You can power your motors with a laboratory high-voltage supply, a Van de Graff generator, or a Olleg machine or any other high-voltage source.
It employed stiffbacked single-edge razor blades as electrodes. Do not connect the antenna to an insulated object of substantial size, such as an automobile.
So the rotor-electrode distance was constantly changing.
Twelve stationary thimbles supported by insulating columns elecrrostatic spaced around the disk to graze the rotating metal spheres. Notwithstanding the problem of handling potentials on the order of a million volts without effective insulation materials, Jefimenko foresees the possibility of at least limited application of corona power machines.
And so are the motors. Such motors develop mechanical force through the interaction of magnetic fields that are generated with high electric current at low voltage, as Michael Faraday motkrs in One model consists of a series of disks mounted on a common shaft. If the electdostatic are spaced too close, sparks tend to jump from electrode to electrode around the rotor, thereby in effect short-circuiting the machine. The motor operates on a few microwatts of power.

The cure took about 3 hours. The working surface of the rotors should be made of a fairly thin plastic, such as Plexiglas or Mylar. This rotor olsg sandwiched between four semicircular sectors that are cross-connected [ see illustration ]. Hook the other side of the motor to ground. Jefimenko received his B.

Drill and tap the acrylic and assemble parts with machine screws. He stuck the device jefiemnko and flipped it degrees. The rotor was thus constructed much like a modern flat-plate capacitor. It produces a permanent electrostatic charge in the surrounding space, just as a magnet produces a permanent magnetic field.
The electret reacts to neighboring charges exactly as though it were a charged electrode, that is, it is physically attracted or repelled ooeg on the polarity of the neighboring electrode. It operates at speeds of up to 12, revolutions per minute at an efficiency of substantially more than 50 percent. The discharge globes are traditional for high-voltage machines. 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.
This limitation is circumvented by a novel electrostatic motor invented in by a Russian physicist, A. Motors based on the slot effect can be designed in a number of forms.
Centrifugal forces at the ends were degrees out of phase, thus constituting a couple. The rotor began to spin. He has succeeded in constructing demonstration motors that run continuously off atmospheric electricity.
The energy of the field can be tapped with a simple antenna in the form of a vertical wire that carries one sharp point or more at its upper end. The high-voltage terminals of two or more Leyden jars that carried charges of opposite polarity were positioned to graze the thimbles on opposite sides of the rotating wheel.
Franklin charged his jars with an electrostatic generator. Apart from possible applications electrostatic motors make fascinating playthings. Electret Scientific, Star City, A note of warning is appropriate at this point.
