Definitions

  • the invention relates to a sheet stack for magnetic cores composed of stacked sheet metal lamellae for use in inductive components, such as transformers, choke coils, actuators, actuators such as, for example, solenoid valves, electrical machines and other applications in which magnetic circuits acted upon with an alternating field are used
  • the laminated core has at least one opening parallel to the laminated sheet planes
  • the stacked laminated sheets comprise outer laminated sheets and inner laminated sheets arranged between the outer laminated sheets, the surface of the outer laminated sheets in each case corresponds to the cross section of the laminated core parallel to the laminated sheet planes, several of the inner laminated sheets, the surfaces of which are combined corresponds to the cross section of the laminated core minus a cross section of the opening parallel to the laminated lamella planes, are arranged in the same laminated plane.
  • the invention further relates to a method for producing a bleck package.
  • Such bleck packages are for example from JP-A-2240473 known.
  • Magnetic cores are also known which preferably consist of one another insulated metal fins are stacked around the due to changing magnetic fields otherwise flowing in the magnetic core Reduce eddy currents.
  • sheet metal packages show as magnetic cores the advantage that the required Windings can be pushed over the individual legs, before the magnetic circuit is closed. Furthermore leaves so through the choice of the dimensions of the laminated core easily set a more or less large air gap.
  • Such laminated cores are held together from individual laminations and screwed or glued together. at the screw connection has the disadvantage that Eddy currents can arise in the bolt, so that preferably non-conductive material is used there got to.
  • openings in the laminated cores to be provided in the direction of the sheet plane, i.e. the level of the individual stacked laminations.
  • This requires usually a milling or drilling, whereby the Isolation of the individual sheets from each other at least on the range the opening thus created may be impaired.
  • this exciting machining requires considerable Costs.
  • the object of the present invention is now a laminated core indicate that with at least one opening in sheet metal level is provided without significant additional costs for the production the opening arise and without impairments isolation of the sheets from each other.
  • FIG. 1 An embodiment is shown in Fig. 1.
  • Fig. 2 shows the arrangement of the laminated core according to Fig. 1 in parts different from each other.
  • the laminated core 1 has an E-shaped cross section and an inner opening 2 with a rectangular cross section, the for mounting bolts or Adjustment spindles of various types can serve.
  • the opening can be used as an actuator in valves for example as a bushing for the valve guide to be used.
  • the laminated core 1 consists of an outer leg 3, another outer leg 4 and a middle leg 5, in which the opening 2 is located.
  • the dimensions of the Surface of the outer sheet metal lamellae 6 are in Fig. 2a and 2c, while FIG. 2b shows the inner sheet metal fins 7 and 8 each with a U-shaped cross section.
  • the U-shaped cross section of the inner sheet metal fins 7 and 8 is chosen so that a sheet metal plate 7 and a Sheet metal lamella 8 has a surface, the area around which The area of the opening 2 is smaller than the area that cover the outer metal fins 6.
  • the stacking technique using Warts and depressions applied.
  • the metal lamellas are for each inner one Sheet metal lamella three warts and depressions 9 provided in the same applies to the outer sheet metal lamellae 6 six warts and depressions 9 each.
