Permanent magnet systems
AMT&C LLC offers a full range of services in calculations, design and manufacturing of permanent magnet assemblies with required magnetic field configuration. Many years experience in complicated magnetic systems production combined with application of modern most effective magnetic materials permit us to reach high parameters:
- to produce, with permanent magnet systems, the magnetic flux density up to 3 Tesla and more;
- to reach high homogeneity - up to 10-5;
- to create magnetic systems with complicated field pattern;
- to produce adjustable magnetic field generators on the basis of permanent magnets. The magnetic field changing rate in such systems can reach 10 Tesla per second.
AMT&C LLC developed several types of axial magnetic field systems of permanent magnets that allow to reach highly homogenous field in a wide ranges of magnetic flux density and working area size. Examples of magnetic systems, given in the table,…
The compact system of permanent magnets NdFeB, designed according to the principle of the dipole Halbach-structure, allows to get, inside the bore, rather homogeneous magnetic field with the magnetic flux density up to 2-3 Tesla. The system can be an…
This type of highly intensive magnetic field generator is based on the dipole Halbach structure principle and offers the possibility to vary the field value, including field polarity reversal, from –Bmax up to +Bmax. The magnetic induction vector is directed…
This type of magnetic field sources also is based on the principle of dipole Halbach-structure, but the special design permits to get an optical access to the sample under investigation along several directions with a rather wide aperture.
AMT&C LLC produces a wide variety of magnetic blocks – basic components of the pipeline flaw detectors. Thanks to the stable quality and guaranteed high magnetic parameters of our magnetic assemblies we supply them for largest Russian companies - producers…
High-tech research is, perhaps, that particular market where the scientific potential and expertise of AMT&C’s research and engineering personnel can most fully be realized and appreciated.
This magnetic system is specially designed for non-destructive testing of pumped vacuum devices, that required the creation of a uniform magnetic field not only in the center of the operating bore, but in the toroidal region of large size. The…
This type of magnetic systems is developed for NMR applications, but can also be used for other tasks requiring the highly homogeneous magnetic field in the significant working volume.
The magnetic system of this field source is also built on the principle of nested cylindrical Halbach-structures. An important feature is the presence of two motors, controlled independently, so it is possible to manage the change not only the magnitude…
For testing cardio-stimulators and other medical devices, a set of the magnetic field sources was designed having a magnetic flux density in the working area from 1 to 300 mT.
