Claim Text:
1. Method for soldering a stator of an electric machine to a cooler with the steps: coating of the stator and/or the cooler, at least partially, with a layer of solder; bringing together of the stator with the cooler such that the layer of solder is between the stator and the cooler; and heating of the cooler to the melt temperature of the layer of solder, in order to produce a solder connection between the stator and the cooler, wherein the cooler is passed through by at least one fluid channel, characterised in that the step of heating comprises the steps: pouring of a high-boiling liquid into the fluid channel; inductive heating of the cooler on its side facing away from the stator up to evaporation of the boiling liquid; and condensing of the boiling liquid in the fluid channel, in order to heat the layer of solder to its melt temperature.
