Abstract
A stator arrangement and a rotor arrangement for a transverse flux machine. The stator arrangement comprises an annular stator back yoke having a number of stator poles designed in the manner of claw poles. The rotor arrangement includes number of rotor poles designed in the manner of claw poles and connected to each other to form an annular rotor body enclosing a unipolar ring magnet magnetized in an axial direction. In the stator arrangement, the stator back yoke includes a first laminated stack of metal sheets whose laminations are stacked in an axial direction, and the stator poles include a second laminated stack of metal sheets whose laminations are stacked in a tangential direction. In the rotor arrangement, the rotor poles include laminated stacks of metal sheets whose laminations are stacked in a tangential direction.
