The subject of research is the traction switched reluctance motor for transport systems with uneven air gap. The calculation of the forces of one-way magnetic attraction during displacement of the rotor is carried out. It has been shown that these forces reach high values and exert an influence on the bearings leading to their premature wear. Measures are proposed to reduce the influence of one-way magnetic attraction forces and to increase the reliability of the bearing unit.
