Definitions

  • the figure shows schematically in section a preferred embodiment of the ring band core according to the invention.
  • the support ring 1 which has a thickness of about 0.3 mm, tape layers 2 are wound from soft magnetic material.
  • the support ring 1 has a recess 4 in the area of the air gap 3, which is wider than the air gap 3. It can clearly be seen that for the air gap 3 only tape layers 2 made of soft magnetic material were cut.
  • the support ring 1, on the other hand, was not severed and can therefore continue to ensure the fixation and spacing of the air gap 3.
  • the entire surface of the ring band core consisting of the support ring 1 and the soft magnetic band 2 wound thereon is provided with an insulation layer 5.
  • This insulation layer 5 serves for additional stabilization of the wound tape layers 2 and is also intended to avoid possible short circuits between the magnetic tape layers 2 and the wires of the winding.
