Definitions

the innovation relates to a laminated core composed of stacked laminations for magnetic cores for use in inductive components, such as transformers, choke coils, actuators, actuators such as. B. solenoid valves, electrical machines and other applications in which an alternating field applied magnetic circuits are used.
Magnetic cores are known which are stacked from sheet metal lamellae which are preferably insulated from one another in order to reduce the eddy currents otherwise flowing in the magnetic core due to changing magnetic fields.
laminated cores as magnetic cores have the advantage that the required windings can be pushed over the individual legs before the magnetic circuit is closed. Furthermore, by choosing the dimensions of the laminated core, a more or less large air gap can easily be set.
Such laminated cores are held together from individual laminations and screwed or glued together. When screwing, however, there is the disadvantage that eddy currents can arise in the bolt, so that preferably non-conductive material must be used there.
the object of the present innovation is now to specify a laminated core that is provided with at least one opening in the plane of the sheet, without significant additional costs for producing the opening and without impairing the insulation of the sheets from one another.
the solution to the problem is, according to the innovation, that in order to form an opening running in the direction of the plane of the sheet metal lamellae (sheet metal plane) in the area of this opening between outer sheet metal lamellae, the surface of which corresponds to the cross section of the sheet metal stack in the sheet metal plane, several inner sheet metal lamellae with reduced Surface dimensions are arranged, the surface of which corresponds to the cross section of the laminated core without the opening.
each inner sheet metal lamella with a reduced cross section either has at least two warts and depressions or bores or - if only one wart and one depression is provided, this is carried out with a non-circular cross-section.
inner sheet metal lamellae with a reduced cross-section which have the same dimensions to one another. If round or oval openings are to be created, the dimensions of the surface of successive inner sheet metal plates with a reduced cross section must change from sheet metal level to sheet metal level in accordance with the desired opening shape.
FIG. 1 An embodiment is shown in Fig. 1.
Fig. 2 shows the arrangement of the laminated core according to Fig. 1 in different parts.
the laminated core 1 has an E-shaped cross section and an inner opening 2 with a rectangular cross section, which can be used to hold fastening bolts or adjusting spindles of various types.
the opening can be used, for example, as a bushing for the valve guide.
the laminated core 1 consists of an outer leg 3, a further outer leg 4 and a middle leg 5, in which the opening 2 is located.
the dimensions of the surface of the outer metal plates 6 are shown in FIGS. 2a and 2c, while FIG. 2b shows the inner metal plates 7 and 8, each with a U-shaped cross section.
the U-shaped cross section of the inner sheet metal plates 7 and 8 is chosen so that a sheet metal plate 7 and a sheet metal plate 8 each have a surface whose area is smaller by the area of the opening 2 than the area covered by the outer sheet metal plates 6.
the stacking technique is used with the help of warts and depressions.
three warts and depressions 9 are provided for each inner sheet metal lamella, and six warts and depressions 9 are respectively arranged in the outer sheet metal lamellae 6.
