The present invention relates to a rotor for an electric machine, comprising a rotor shaft which extends in an axial direction, and a basic body, which is arranged concentrically around the rotor shaft and is fastened on said rotor shaft for rotation therewith, wherein permanent magnets are embedded in the basic body, and wherein the basic body has collecting webs, which adjoin the permanent magnets, wherein the permanent magnets protrude beyond the collecting webs on that side of said permanent magnets which faces the rotor shaft. The present invention also relates to a rotor, in particular according to the invention, for an electric machine with a rotor shaft, which extends in an axial direction, and a basic body, which is arranged concentrically around the rotor shaft and is fastened on said rotor shaft for rotation therewith, wherein the basic body has sectors, which are spaced apart from the rotor shaft and between which in each case one permanent magnet is arranged in spider form, wherein the distance between the sectors and the rotor shaft is greater than the distance between the permanent magnets and the rotor shaft. The present invention also relates to an electric machine having the rotor according to the invention and a steering drive having the electric machine.
