The invention relates to a process for the impregnation of air core reactors or parts of air core reactors and impregnated air core reactors or parts thereof obtainable by said process.

Impregnation of air core reactors

The method of manufacturing a sheet stack for electromagnetic assemblies, consisting of ferromagnetic material, includes forming the sheet stack from raw magnetic steel sheets in a shaping tool without the use of spacers, if necessary with the help of positioning aids, and simultaneously introducing a hardenable mixture into the shaping tool in order to totally surround the sheet stack and to form an anti-corrosion layer and hardening or hardening out this casting compound according to the pressure-gelating method to connect the sheets together and to form the finished sheet stack in one single working step. An electromagnetic assembly including at least one of the sheet stacks and an additional component is made in the same working step by a method including making the finished sheet stack in accordance with the foregoing pressure-gelating method, connecting the finished sheet stack to the additional component to form the assembly and surrounding the assembly with the mixture in order to form the anti-corrosion layer.
