Abstract
The invention relates to a method for adhesively bonding a magnet onto the surface or into a slot of a rotor or stator of an electric motor or a generator, wherein i) the surface or surfaces to be glued of the magnet, rotor or stator are pre-coated with an adhesive that is not liquid at 22° C. and that does not cure without an activation step, iii) the magnet is brought into contact with the rotor or stator at the adhesive location, and iv) the adhesive is activated by heating or by high-energy radiation so that it cures, characterized in that the adhesive comprises a) at least one reactive epoxide prepolymer, b) at least one latent hardener for epoxies, and c) one or more elastomers. The adhesive preferably comprises a blowing agent. The invention further relates to a corresponding pre-coated magnet.
