Abstract
A segmented annular stator for an electric machine, including a concentrated winding. The stator includes a plurality of circular ring segment-shaped stator segments which are substantially identical and each of which has a stator tooth with a first recess protruding into the stator tooth in the circumferential direction and a second recess protruding into the stator tooth in the circumferential direction. A multilayer coil made of a wound winding wire is arranged in the first recess and the second recess, and the first recess and the second recess each has a recess depth which increases with the radius of the annular stator, wherein the outermost winding layer of the coil in the first recess and the outermost winding layer of the coil in the second recess of an adjacent stator tooth in the circumferential direction engage into each other in the circumferential direction in an electrically insulated manner so as to intersect in the radial direction.
