The subject application provides a rotor assembly for radial/axial synchronous reluctance machines, a system assembly and method for producing a rotor assembly. The rotor assembly (100) comprises an elongated body (110) which cross-section comprises at least one pair of a first rotor magnetic pole segment (112) and a second rotor magnetic pole segment (112). The rotor assembly (100) is arranged such that, when being exposed to a magnetic flux, a free end of the first rotor magnetic pole segment (112), called first free end (1122a) and a free end of the second rotor magnetic pole segment (112), called second free end (1123a), are facing each other, the first free ends (1122a,1123a) having no surface contact with one another or a minimum surface contact (1125) with one another, thereby forming a flux barrier for inhibiting the magnetic flux from flowing between the first free ends (1122a, 1123a).
