The present application relates to a segmented stator, in particular for a generator of a wind turbine. A segmented stator, in particular for a generator of a wind turbine, is described. The stator includes a plurality of teeth and slots for the coil windings, wherein the teeth extend from a yoke of the stator in a radial direction of the stator. The stator comprises at least first and second stator segments having first and second end surfaces, respectively, in a 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 a first protrusion protruding in a circumferential direction of the stator, the first protrusion forming a first tooth extending from a yoke of the stator in a radial direction of the stator, and a first recess therebetween. The second end surface includes a second protrusion protruding in a circumferential direction of the stator, the second protrusion forming a second tooth extend
