Abstract

A rotor for a modulated pole machine, the rotor being configured to generate a rotor magnetic field for interaction with a stator magnetic field of a stator of the modulated pole machine, wherein said rotor comprises: a tubular support structure defining (201, 301) a circumferential mounting surface, the tubular support structure comprising a plurality of elongated recesses (202) in the mounting surface, the elongated recesses extending in an axial direction of the tubular support structure and a plurality of permanent magnets (203) arranged at the mounting surface of the tubular support structure and magnetised in the circumferential direction of said rotor so as to generate the rotor magnetic field, the permanent magnets (203) being separated from each other in the circumferential direction of the rotor by axially extending rotor pole sections (204) for directing the rotor magnetic field generated by said permanent magnets in a radial direction, wherein at least one permanent magnet (203) or one rotor pole section (204) extends at least partly into one of the plurality of recesses.
