Abstract
For the production of a plate packet for magnet cores that have an opening in the longitudinal direction of the plate lamellae, inner plate lamellae with reduced cross-section are stacked in the region of the opening. Of these inner lamellae, at least two lie in one plate plane and together have a surface that is reduced in size by the cross-section of the opening in comparison to the size of the outer plate lamellae.
Claims11
A plate packet for a magnetic core for charging a magnetic circuit with an alternating field, comprising:
- a plurality of plate lamellae disposed in a stacked assembly respectively in a plurality of parallel, adjacent plate planes;
- said plurality of plate lamellae including first and second sets of outer plate lamellae each having the same cross-section in said plate planes;
- and
- at least two sets of inner plate lamellae disposed between said first and second sets of outer plate lamellae, said at least two sets of inner plate lamellae being spaced from each other and forming an opening in said plate planes between said first and second sets of outer lamellae, said at least two sets of inner plate lamellae, in combination, having a cross-section which, except for said opening, is the same as the cross-section of said first and second sets of outer lamellae.
