Abstract: A segmented stator for a generator, for a wind turbine is provided. The stator includes a plurality of teeth and slots for coil windings, wherein the teeth extend from a yoke of the stator in a radial direction of the stator. The stator includes at least a first stator segment having a first end-surface in a circumferential direction of the stator and a second stator segment having a second end-surface in the circumferential direction of the stator, wherein the first and second end-surfaces are arranged adjacent to each other to form the stator. The first end-surface includes first protrusions protruding the circumferential direction of the stator and first recesses therebetween, the first protrusions forming first teeth extending from the yoke of the stator in the radial direction of the stator.

Abstract: A method a magnet system for a rotor of a permanent magnet electrical machine includes: a first module including a first support member; a second module includes a second support member; wherein the first module includes a first permanent magnet supported by the first support member and/or the second module includes a second permanent magnet supported by the second support member, wherein the first support member and the second support member have respective contact portions which are at least partly structurally complementary to each other allowing to arrange the first module and the second module adjacent to each other in the axial direction, while the contact portions contact each other and causing traverse shift in a direction travers to the axial direction, when pushed towards each other in the axial direction.

Abstract: An electrical machine is provided including a stator with a stator core, a plurality of stator teeth protruding radially from the stator core, and a plurality of stator coils, wherein each stator coil is wound around at least one stator tooth of the stator and includes at least one coil head protruding in axial direction beyond the stator core, wherein the stator includes a stator extension structure with a plurality of magnetic flux-guiding extension segments each protruding axially from a stator tooth into an area surrounded by at least one of the coil heads.
