In order to allow a rotating electrical machine, which uses a permanent-magnet rotor with a flux-concentration construction for a rated power of more than 100 kW, to be assembled as easily as possible, two mutually adjacent half-yokes of two poles as well as magnets arranged between them in each case form a pole element which can be fixed on its own on the rotor body.

1. A multipole, permanent-magnet rotor for a rotating electrical machine, comprising:permanent magnets designed to be flat in a magnetization direction are arranged radially with respect to a rotor axis in slot-like spaces between two yokes fixed on a rotor body, wherein each yoke is subdivided in a circumferential direction into two mutually adjacent half-yokes which extend over half of one pole pitch, andthe two half-yokes of the two yokes are arranged alongside one another and are connected by end plates to form a pole element, the pole element fixed on the rotor body,wherein each of the two half-yokes is fitted with permanent magnets on a surface facing a slot-like intermediate space that is filled with material configured to expand under the influence of impregnation resin.2. The permanent rotor as claimed in claim 1, wherein the permanent magnets are secured radially by double wedges.3. The permanent rotor as claimed in claim 1, wherein the pole element is subdivided into a number of partial pole elements in an axial direction of the rotor.4. The rotor of claim 1, wherein the permanent magnets are cuboid.5. A method for producing a permanent-magnet rotor, comprising:arranging radially permanent magnets which are configured to be flat in a magnetization direction with respect to a rotor axis in slot-like spaces between two yokes fixed on the rotor body,wherein each yoke is subdivided in a circumferential direction into two mutually adjacent half-yokes which extend over half of one pole pitch,arranging the two half-yokes of the two yokes alongside one another and connecting the two half-yokes by end plates to form a pole element, the pole element fixed on the rotor body,wherein each of the two half-yokes is fitted with permanent magnets on a surface facing a slot-like intermediate space that is filled with material configured to expand under the influence of impregnation resin, andmagnetizing the magnets once the two half-yokes have been joined together to form a pole element.
