This paper presents a novel multi-degree-of-freedom spherical reluctance driving joint with magnetic levitation. The analysis of operation mechanism and the joint's magnetic conduction of the gap are deduced by means of the way to magnetic segmentation. The relationship between electrical and mechanical energy conversion is analysed and then the radial suspension force and the tangential suspension torque are calculated. The simulation experiments show that the system of driving joint has well static and dynamic characteristics。 Streszczenie. W artykule zaprezentowano kuliste reluktancyjne polączenie napedowe o wielu stopniach swobody. Przeanalizowano wlaściwości bazując na magnetycznej segmentacji. Obliczono promieniową sile i tangencjalny moment.(Analiza sily i momentu kulistego napedu magnetycznego metodą segmentacji pola magnetycznego)
