Abstract
A stator of an electric machine has an annular stator body with a multiplicity of winding slots. The winding slots protrude into the stator body in the manner of a pocket from a ring interior. Respective windings are disposed in the winding slots and the slots are sealed toward the ring interior with slot-liner elements. The slot-liner elements of all the winding slots are combined to form a slot-liner cage. The slot-liner cage is formed with circumferential cage rings at the ends of the slot-liner elements. The cage rings have an interruption at a circumferential point. The circumferential point has a self-retaining lock geometry which prevents an autonomous opening of two intermeshing ring ends of the cage rings.
