- TASHKENT, Uzbekistan
(UPI) -- An Uzbek inventor said he has created a type of electrical
generator that does not rely on the principle of electromagnetic
induction -- on which all existing generators are based.
-
- The new generator employs a concept called magnetic
conductivity modulation and it has potential applications in industry,
communications, households and even the military, explained Vladimir
Matveev, the inventor, a specialist in electronics.
-
- Matveev said he is convinced he has created a
fundamentally different machine.
-
- "All electrical machines I know are based on the
principle of interaction between the magnetic fluxes (lines of force) of
their rotor (rotating member) and stator (portion that remains fixed),"
he explained.
-
- Such machines, Matveev said, are based on
electromagnetic induction, a property of energy discovered by Michael
Faraday, an English physicist and chemist, in the 19th century. The
machines produce electrical current either by moving a conductor across
a magnetic field or by regulating the flux of that field.
-
- "My machine has a principal difference," Matveev
told United Press International. "The magnetic field of its stator does
not interact with the magnetic field of the rotor (because) its rotor is
not a magnet -- the rotor only changes the magnetic resistance of the
stator," he said.
-
- The stator in Matveev's generator contains a
magnetic core with a permanent magnet and a detachable winding. A rotor
with changeable magnetic resistance is placed at a cutoff point in the
core's magnetic field. It is composed of alternating magnetic and air
parts and can operate in either linear or rotary form.
-
- When the rotor is set in motion, its alternating
components pass through the magnetic core's cutoff point. When the
magnetic part passes through the cutoff point its magnetic resistance
decreases. When the air part passes through, its resistance increases.
-
- This pulsing of resistance results in changing the
magnetic conductivity of the magnetic core, which in turn produces an
alternating electrical current in the core's winding. The frequency of
the winding's current can be controlled by regulating the rotor's speed
or by changing certain qualities of its magnetic or air parts. Also, the
generator's electrical output -- its voltage -- can be controlled by
changing the configuration of the rotor's components, Matveev explained.
-
- Matveev said his generator is different from an
invention by Howard Johnson of the United States. Johnson discovered how
to build motors that can run without input of electricity or any other
kind of external energy. He obtained a patent in 1973 for describing
electrical generation using only the energy contained in the atoms of
permanent magnets.
-
- Matveev also said some Russian inventors have
experimented with a generator similar to his. Their generator changes
its magnetic conductivity by changing temperature. However, the machine
requires a lot of time to be heated and cooled alternately and results
in a current frequency much lower than what generally is used in
industry. Moreover, the Russian generator requires high steel density
and greater mass.
-
- Matveev's machine generates electric energy of
industrial frequency. Furthermore, he said his machine is simple,
reliable and requires less steel and mass than conventional generators.
It also can be adapted to flows of low speeds, such as weak water or
wind streams. Matveev tested the generator in his former household in
Kazakhstan before he patented it in Uzbekistan.
-
- "I want to pass the invention on to all mankind," he
said.
-
- Boris Abdurakhmanov, director of the Uzbek Koinot
(Cosmos) design office and head of the laboratory of semiconductors and
photoelectricity of the Institute of Electronics of the Uzbek Academy of
Sciences, told UPI: "Matveev has offered a fundamentally new approach to
a problem of the creation of electric power generators."
