Abstract
A rotor for an electrical machine includes a base body, a plurality of permanent magnets which are arranged axially in rows on an outer surface of the base body. At least two of the permanent magnet rows are arranged so as to be mutually offset in an axial direction. First and second locking plates are respectively arranged at axial end faces of the base body to secure the rows of permanent magnets in the axial direction, with the first and second locking plates each having a surface which rests on respective axial ends of the permanent magnet rows. A bandage is wound around the base body to fix the permanent magnets to the outer surface of the base body.
