- In this section we present only a small part of the magnetic
elements and system produced by MMT Company. We are aware that
the presented products might not meet all the needs of the perspective
Customer in details (or even in more general issues). However,
this list shows the real potential of our Company and also indicates
the industrial branch region we work in.
Devices for magnetic processing of water of the MABP® series are
the novel and perspective solution presented by MMT Company. Hydromuiltipoles®
are special magnetic systems of such devices used for prevention
of scale build-up in heat exchange systems. Boilers, heat exchange
elements of compressor stations, electrical heating elements of
laundry and dish-washing machines can be safeguarded against scale
build-up if MMT hydromultipoles® are used at their
water input. More than 20000 Hydromultipoles® delivered
by MMT Company to the customers ensure an effective protection from
scale build-up and also facilitate old scale removal.
Magnetic focusing systems (MFS) for electrical vacuum devices
are the traditional products of MMT Company. Our Company develops
and produces MFS with homogeneous, reversal, and periodic focusing
magnetic fields for stabilization of the electron beams in multibeam
clystrons, traveling wave tubes and backward wave tubes, magnetrones,
gyroscopic devices, etc.
In the calculation and design of MFS all the essential parameters
are taken into account: real geometry of the interaction volume,
cathode design, cathode voltage and beam perveance.
An essential part of permanent magnets the manufactured all around
the world is used in production of magnetic
systems of electrodynamical loudspeakers.
Magnets based on strontium and barium hexaferrites are commonly
used to keep the price of the magnetic system relatively low. However,
in a wide range of applications high sound pressure and articulation
combined with low weight and size characteristics are absolutely
necessary. In this case rare earth magnets are used.
MMT Company has developed and produced magnetic systems with a completely
screened magnetic flow. Such systems of the type "Siren"
(Lilac) are manufactured for electrodynamical loudspeakers of police,
emergency, fire-fighting vehicles etc. Our magnetic systems are
unsurpassed on the Russian market according to the complex of parameters.
MMT Company has developed similar devices for the companies that
produce audio equipment for cinema halls and show business.
Contactless electrical machines with an active
rotor are another perspective field for application of rare
earth permanent magnets manufactured by MMT Company. We have established
a long-term cooperation with many companies producing such electrical
machines both at development and production stages. Our Company
has developed a special technological complex that allows to produce
multipole rotors of electrical motors with weight in the range from
several grams up to tens of kilograms. We deliver certified, bandaged
and balanced rotors to our Customers.
MMT Company presents a series of magnetic
separators and iron catchers for application in production of
flour, mixed fodder, dye-powders, and other dispersed media. Our
magnetic separators can be also used in manufacturing of plastic
products from polypropylene and polyethilene granules. We produce
separators with both traditional and novel design.
We have developed another device from this class, a magnetic
separator for removal of ferromagnetic impurities from drill liquid
before it goes to a vibrosieve. This drill liquid separator is manufactured
for oil and gas producing companies that use the technology of side-track
boring for enhancement of oil recovery.
MMT Company in collaboration with Design Company "Mir",
which is the largest Company Russia producing equipment for public
entertainment, has developed the magnetic
system for vortex current braking (MSVCB). This system is applied
in the entertainment complex "Free fall tower" to reduce
the velocity of the carriage weighing 1500 kg after a free
fall from 22 m high to less than 1 m/sec. The maximum
braking force is approximately 3000 kg.
The principle of the MSVCB is based on
the interaction of vortex currents in bulk conductors during their
motion in magnetic field produced by the magnetic system. The vortex
currents interact with the magnetic field and originate the force
counteracting the motion, according to the Lenz's law.
MMT Company also produces:
-
powerful magnetic systems for complexes for
non-destructive diagnostics of long-legth ferromagnetic constructions,
including oil and gas trunk-pipelines
-
multipoles for plasma confinement systems
-
magnetic systems for milling catchers used
for repair and recovery of oil and gas wells
-
-
magnetic clamps for various applications with
release force form 15 up to 3000 kg
-
various probes-indicators of ferromagnetic
inclusions
These devices and several others are presented in section General
purpose magnetic systems.
An applied software package "BEMS" developed by the employees
of MMT Company is used for mathematical support of the magnetic
system design. This package allows a thorough analysis of the configuration
of magnetic systems and the topography of magnetic fields generated
by these systems.
This package makes use of the advanced capabilities of modern computer
technologies that allow to extend the range of complexity of designed
systems and solve the problems in three-dimensional formulation
with input data and results visualization. The principal algorithms
of the "BEMS" package are based on the numerical techniques
for the solution of mathematical physics problems described in scientific
literature.
Practical results of application of this package are realized in
the design of more than 300 magnetic elements, magnetic systems
and complete products with different production volumes. Basic groups
of such products are presented in Section «Typical
product designs».
