1. A rotor arrangement in a unilateral transverse flux machine with flux concentration which is in interaction via an air gap with a coaxially arranged stator arrangement with stator poles and an interposed annular winding, comprising rotor pole shoes in the circumferential direction with interposed permanent magnets having alternating poles, wherein a rotor pole unit including the rotor pole shoes is provided for each stator pole unit of the stator arrangement, with adjacent rotor pole shoes of one phase being connected with one keeper each, each said keeper being separate from its respective rotor pole unit, and wherein each said keeper comprises punched soft-iron sheet elements stacked in a radial direction and each of the rotor pole shoes comprises punched soft-iron sheet elements stacked in the axial direction.
