Definitions

  • the shielding effect of the support body 8, 18 consisting of electrically conductive material (preferably an aluminum alloy) prevents the flow in the shielded area from entering or exiting transversely to the longitudinal axis of the laminated core 9, 19, so that corresponding additional losses are avoided.
  • electrically conductive material preferably an aluminum alloy
  • By bending the laminated core near the side walls of the support body acute-angled sectors are created with a relatively large exit area for the magnetic flux 31 of the transverse field and excessive excessive heating in the laminated core and support body due to high flux concentration are avoided.
  • the magnetic flux 31 is made possible to enter and exit the edges of the individual sheets without having to penetrate additional individual sheets.
  • the laminated core is very close to the coil 3 except for the drainage distance 29 or the spacing caused by the insulation 12.
  • the individual sheets which are particularly advantageously arranged for the flow 31 of the transverse field in the lateral area of the laminated core are also for Management of the river 32 of the normal field is suitable.
