1. A reluctance machine with a stator and a rotor, wherein the rotor comprises an encapsulated body configured to rotate about an axis of rotation of the rotor, and a plurality of flow guide segments, wherein the flow guide segments form poles of the rotor and are arranged in a circumferential direction about the axis of rotation and are embedded in the encapsulated body, wherein a material of the encapsulated body is disposed between adjacent flow guide segments in the circumferential direction, wherein each flow guide segment has a ferromagnetic region which extends in a curved or trapezoidal shape, wherein each flow guide segment has limbs extending toward the stator which define a free space therebetween, and wherein the material of the encapsulated body is disposed in the free spaces to act as a flow barrier.
