摘要
A rotor having a number of tangentially magnetized permanent magnets tangentially evenly distributed and arranged both in the center region and in the outer regions in the axial direction is disclosed. Flux-guiding elements between the permanent magnets guide the magnetic fields of the permanent magnets radially toward the center region of the stator. The flux-guiding elements comprise a plurality of sheets stacked on one another in the axial direction. The sheets in the outer regions are smaller than the sheets in the center region. The sheets arranged in the outer regions are surrounded on their radially outside end by a retaining apparatus. Form-fitting elements transmit centrifugal forces acting on the sheets arranged in the center region are transmitted to the sheets arranged in the outer regions.
