摘要
A method for joining core laminations by adhesive force to form a soft-magnetic laminated core by applying a coating that is wettable with epoxy resin to top sides and undersides of each sheet. The sheets are separated into core laminations made of soft-magnetic sheets, which are stacked to form a core lamination stack, and a cured adhesive introduced in a state of low viscosity into interstices between the core laminations. The core lamination stack has intermediate layers between the core laminations. For this purpose, the core laminations comprise a final-annealed, crystalline CoFe alloy, an adhesive-wettable top side and an adhesive-wettable underside. Together with the intermediate layers, the core laminations form a dimensionally accurate laminated core. The laminated core has a substantially adhesive-free contour consisting of contour surfaces of the core laminations. The adhesive is solvent-free in its low-viscosity state.
