Abstract

In an electrical axial flow machine, comprising a stator and a rotor, wherein either the stator comprises a coil arrangement and the rotor is provided with permanent magnet elements, or wherein the rotor comprises a coil arrangement and the stator is provided with permanent magnet elements, the stator is arranged spaced from the rotor under the formation of an air gap, each of the magnetic flux yokes has several neighbouring magnetic flux poles, the coil arrangement has at least one hollow cylindrical winding which is at least partially encompassed by magnetic flux yokes, the magnetic flux poles each have an outside which is oriented to the permanent magnet elements beyond the air gap, neighbouring permanent magnet elements in the circumferential direction have an alternating magnetic orientation towards the air gap, at least several of the magnetic flux poles are in certain positions of the rotor relative to the stator at least partially oriented in alignment with the permanent magnet elements, the magnetic flux yokes are formed from several ring cylinder segments, one support disk each is arranged between neighbouring magnetic flux yokes for the ring cylinder segments of the magnetic flux yokes in the direction of a longitudinal centre axis of the magnetic flux yokes, with the support disk comprising means for the mechanic positioning of at least two ring cylinder segments, forms a thermal path to a heat sink and has an electrically insulating effect.
