Research
and production Company
«Megapolis Technologies» Ltd.
The progress in science, technology and industry is due
both to the development of new advanced technological processes
and creation of the devices for their practical realization.
User-end properties of each device are characterized by the
three following parameters: mass, dimensions and power consumption.
These parameters should be minimized, whereas the functional
parameters should be increased. Application of permanent magnets
allows to solve this problem for many applications in electrical
engineering, electronics, telecommunication and other fields.
The higher is the specific energy, time and temperature stability
of the permanent magnets, the greater is the effect of mass,
dimension, and power consumption reduction. Essential optimization
is also possible due to the customization of magnet geometry.
Periodic magnetic systems of the microwave devices, gyroscopes,
electric motors, non-contact bearings and couplings, loud-speakers,
tomographs, mass- and NMR-spectrometers are among the applications
of permanent magnets. This list is by far not completed. Materials
based on the alloys of rare-earth metals with iron and cobalt
have a special place among the multitude of compounds used for
permanent magnets. Such alloys have the best characteristic
compared to the other known materials. Therefore the magnets
based on rare-earth and transition metals alloys draw a lot
of attention in research, production and consumer sectors. They
find still more and more applications in technology.
A great progress has been made over the past decades in
development and production of such permanent magnets. The value
of the maximum energy product for the Nd-Fe-B magnets is (ÂÍ)max = 50 MGaussOersted,
which exceeds by a factor of four the value for the best Al-Ni-Co
magnets.
Research and production Company MMT was created to provide the
most advanced high-energy permanent magnets based on the Nd-Fe-B
alloys for the consumer market. Therefore the structure of the
Company was planned as a small-scale production complex capable
of efficiently supplying the Customers with permanent magnets.
However, in the course of the reforms in the industry we found
almost no demand on the magnets as such. Customers did not need
magnets, but the magnetic fields produced by permanent magnets.
Even this is not quite the case. The customers rather need the
magnetic fields produced by magnetic elements and magnetic systems
which have the following constituents: permanent magnets, soft
magnetic parts that facilitate concentration and configuration
of the magnetic flow in the operation region, and also non-magnetic
construction elements made of metallic and non-metallic compounds.
According to this demand, the new structure of the Company emerged,
quite different from the one initially planned. Research and production
Company MMT (RPC) can now completely rely on its own resources
both in research and development, and in the production cycle.
RPC MMT has the following departments: Chief designer service
(Design department and the Computational support group), Department
for the development of advanced processes and equipment with permanent
magnets, Production department for sintered permanent magnets
production in vacuum, Assembly department for the production of
magnetic systems, and the Quality control group.
Since we started to offer complete magnetic systems, only 10-12%
of our Customers purchase the magnets. The majority prefers to
obtain "custom-made magnetic fields" to fix metallic
components in place, focus and transport electron plasma beams,
separate magnetic admixtures, rotate the spindles of electric
machines, process liquids, take the load off the rotation bearings,
transfer rotational or translational motion into closed volumes,
and to decelerate vehicles.
The products made by the MMT Company are widely used in:
- electronics (magnetic focusing systems of clystrons, traveling
wave tubes and backward wave tubes, gyrotrons etc.),
- oil and gas industry (electric motors and hermetic couplings
for submersible pumps, dewaxing units, magnetic barrage and
overshots, elements of diagnostic complexes)
- heat and power engineering (magnetic systems for water processing
for reduction of scale formation),
- motor-car industry (magnetic filters, microelectromotors,
sensors, electromechanical transducers, locking devices),
- municipal economy (water meters, electricity meters, gas meters),
- food industry (high-efficiency magnetic separators and barrages).
Over the past two years delivery of products for oil and gas
industry drastically increased (rotors for the (electric motors
of submersible pumps, magnetic separators and barrages, magnetic
overshots etc.). The part of these products in the overall production
became as high as 73,6%.
The main body of the MMT staff consists of the professionals
with a solid background in the fields of research, development,
and production. Most of them have acquired their experience at
the leading entreprises of electronic and engineering industry:
Federal
state unitary enterprise «Toriy» (former R&D Institute «Titan»),
Design office for special magnets, R&D
and production Company «Pluton», R&D
and production Company «Kompozit» (formerly «Energia»), Moscow
factory for polymetallic compounds.
MMT has good traditions of long term cooperation with the researchers
from the Departments of Physics and
Chemistry of the M.V. Lomonosov
Moscow State University, Chair
of magnetism of the Tver State University, Research laboratories
of the Moscow Institute for Engineering
and Construction, Departments of the General
Physics Institute, Institute
for Radio and Electronics, Institute
for Applied Physics of the Russian
Academy of Science. This cooperation and our own practical
experience over a quarter of a century allows the MMT Company
to efficiently solve a wide range of most challenging research
and development problems.
Technological production complex of MMT is equipped with automated
and highly mechanized facilities both of Russian and Western make.
This complex is capable of facing the challenges of highest quality
wares production. Constant upgrade of the equipment allows to
double the yield every year.
Research and production Company MMT is completely in private
ownership.
According to the abovementioned considerations, we offer the
following products and solutions:
- complex solutions: calculation, optimization, production,
and delivery of magnetic systems and elements according to the
Customers' demands,
- production and delivery of magnetic elements and systems for
various applications,
- and only in the third place - permanent magnets of the types
neodymium-Iron-Boron and Samarium-Cobalt.
