ABSTRACT:
A magnetic circuit for inductive electrical devices, preferably reactors, comprises a frame consisting of yokes and side walls, the frame having a preferably rectangular cross-section and being manufactured from laminated magnetic material. At least one core leg having a preferably circular cross-section and composed of laminated magnetic material is arranged in the frame between the two yokes. Between the ends of the core leg and the yokes are arranged cross-flux plates of laminated magnetic material in order to distribute the flux between the legs and yokes. The laminations in the cross-flux plates are oriented to be perpendicular to the laminations in the yokes. Each cross-flux plate covers at least the full width of the yoke and at least the complete width of the core leg. The width of each plate is suitably as great as the diameter of the winding which is arranged around the core leg. Each plate will thus act as a mechanical support for the ends of the winding. It is suitable to arrange spacers of non-magnetic material between the end of the core leg and each plate and between each plate and the adjacent yoke.
