ABSTRACT:
A method for fabricating a rotor arrangement for an electric machine in which a rotor body is provided and permanent magnets made from an isotropic magnetic material are embedded in the rotor body, the permanent magnets being magnetized by an external magnetizing device with a magnetization that corresponds at least approximately to a Halbach magnetic field distribution.
