  "textContent": "A permanent magnet rotor (101) for an axial flux electrical machine of a mobile working machine comprises a shaft (102), a body (103) made of electrically non-conductive material and connected to the shaft, and permanent magnet pole-modules (104) attached to the body and having an axis of magnetization in an axial direction (z) parallel to the shaft. The permanent magnet pole-modules comprise, at least on their outmost regions in the axial direction, structures (105, 107) consisting of parts that are electrically insulated from each other so as to reduce eddy currents in the outmost regions in the axial direction. Losses caused by the air-gap flux harmonics are reduced because the body of the rotor is made of electrically non-conductive material and because the permanent magnet pole-modules comprise the structures consisting of parts that are electrically insulated from each other.",
