1. A rotor for an axial flux motor, a radial flux motor or a transversal flux motor, the rotor comprising a rotation axis which extends in an axial direction, wherein the rotor extends in an annular manner and has in a peripheral direction a large number of permanent magnets, the magnetization of which is orientated in each case in the peripheral direction, wherein the permanent magnets are arranged spaced apart from each other in the peripheral direction, wherein a first material at least comprising a soft magnetic composite is arranged between the permanent magnets, wherein a second material comprising an iron-containing material is further arranged between the permanent magnets, and wherein the second material is a sintered iron-containing material.
