Abstract

The present invention relates to a rotor (1) of an electric synchronous motor with permanent magnets, comprising: a substantially cylindrical rotor body (2) in which at least two receiving channels (3) are formed, in which at least two permanent magnets (4) are disposed, wherein the rotor body (2) has, in the region of the outer surface, a plurality of circumferentially disposed outer slots (5) in which outer bars (6) are inserted, and, in the region closer to the rotational axis of the substantially cylindrical rotor body (2), a plurality of circumferentially disposed inner slots (7) in which inner bars (8) are inserted, end rings (9) which electrically connect the outer bars (6) and/or the inner bars (8), forming an outer cage and an inner cage respectively, wherein the ratio of the electrical conductivity σ<ext> of the material of the outer bars (6) to the electrical conductivity σ<int> of the material of the inner bars (8) falls within the range of 0.17 to 0.35. The present invention also relates to an electric synchronous motor with permanent magnets comprising such a rotor.
