A permanent magnet rotor includes a rotation axis, an inner peripheral magnet that is a cylindrical bonded magnet including a plurality of recesses on an outer peripheral side and holding the rotation axis, and an outer peripheral magnet that is a cylindrical bonded magnet provided on the outer periphery side of the inner peripheral magnet. The outer peripheral magnet includes a plurality of projections that projects toward an inner peripheral side and is fitted into the plurality of recesses of the inner peripheral magnet.

A method for producing a magnet for a rotor of an electric machine has a first phase of producing a magnet blank which includes a step of pressing powders into a magnet mold in the presence of a magnetic field while subjecting the powders to a magnetic field generated by a first magnetization tool. The method further includes a step of densifying the obtained magnet blank and a second phase. The second phase includes finishing the magnet blank by at least one final magnetization step in order to obtain a magnet. The mold is arranged in a densifying chamber, and the densifying step is carried out by flash SPS sintering in the densifying chamber.

A method is used for producing metal sheets for packets of metal sheets of a rotor and of a stator for three-phase drives, in particular for reluctance machines (reluctance motors) made of magnetic, in particular magnetically soft materials by means of additive production processes, in which the magnetizable material is melted and fed to at least one print head which applies the melted material to form a rotor/stator sheet. The melted material is influenced by an applied magnetic field so that the finished rotor/stator sheet has an area with high magnetic conductivity determining the desired direction of flow.
