INDUCTOR FOR THE ANNULAR PERMANENT MAGNETS MULTI-POLAR AXIAL MAGNETIZATION Russian patent published in 2019 - IPC H01F13/00 

FIELD: electrical engineering.

SUBSTANCE: inductor for the annular permanent magnets multi-polar axial magnetization consists of a package with an even number of conductive plates with high electrical conductivity, secured between two dielectric blocks by bolting through dielectric spacers with a gap for the holder with the magnetized magnet accommodation. Plates in the package are electrically in series connected to each other using the electrically conductive contact ring and on the extreme plates have leads for connection to the switching power supply unit. Each of the plates form the closed loop consisting of zigzag and radial conductive sections, respectively repeating the poles and the boundaries shape between the magnetized magnet poles. Plates zigzag conductive parts outer sections have a developed surface along the outer perimeter and are separated by air gaps. Radial conductive sections are located in the plane in the axial direction.

EFFECT: technical result consists in increase in the concentrated magnetic field magnitude in the inductor working zone, and increase in the inductor performance and service life.
