Abstract: A method for fastening a magnet to a laminated core of a rotor for an electric motor includes providing the magnet and the laminated core, providing an adhesive tape, and winding the adhesive tape around the magnet to form a bondable magnet. The adhesive tape includes a backing tape formed by an open-pored nonwoven material, and an adhesive that coats only one side of the backing tape at room temperature and penetrates the open-pored nonwoven material and bonds to the laminated core of the rotor when a temperature of the adhesive is increased by at least 20° C. relative to room temperature. The laminated core may include a cavity for the bondable magnet, and the method may include the step of inserting or fitting the bondable magnet into the cavity. The bondable magnet may be inserted or fitted into the cavity without stress or mostly without stress.
