PROCESS FOR THE PRODUCTION OF LAMINATED CORES AND ELECTROMAGNETIC UNITS PRODUCED THEREFROM
First Claim
1. Method of manufacturing a sheet stack (8,51) for electromagnetic assemblies, consisting of ferromagnetic material, characterised in that the sheet stack (8,51) is assembled from raw magnetic steel sheets (1,52) and is positioned, if necessary with the use of positioning aids, in a shaping tool (28,29), and in that the sheets (1,52) by means of introduction of a hardenable mixture into the tool (28,59) and hardening or hardening out of the casting compound, are then totally surrounded with the mixture and connected together to form the finished sheet stack (8,51) in one single working step.

Abstract
The invention relates to a method of manufacturing a sheet stack (8) consisting of ferromagnetic material, and/or an assembly including such a sheet stack (8) and at least one further component (12, 13, 14). According to the invention, the sheet stack (8) is assembled from raw magnetic steel sheets, and is positioned in a shaping tool. Thereafter, by means of introducing a mixture into the tool and hardening or hardening out of the mixture, the sheets are surrounded by the mixture and connected together to form the finished sheet stack (8) in a single working step. In order to manufacture the assembly, the sheet stack (8) can be connected in the same working step with the components (12,13,14), and the assembly as a whole can be provided with its final electrical, magnetic, mechanical and/or geometric properties (FIG. 2).
