Abstract
A rotor for an electrical machine, in particular synchronous reluctance machine, is provided. The rotor is formed as a cylindrical structure having a magnetically soft element formed with an even number of salient magnetic poles openings for forming magnetic flux barriers. The openings are at least partially filled with a diamagnetic and/or paramagnetic medium and the diamagnetic and/or paramagnetic medium may axially and tangentially fix the magnetically soft element relative to the rotor. A method for producing such a rotor and apparatus using the rotor, including a reluctance motor, in particular a synchronous reluctance motor, that uses the rotor are provided.
