Abstract: Calculation and the analysis of forces of a one-way electromagnetic attraction operating on bearing unit in the traction drive of switched reluctance type taking into account eccentricity of a rotor are given. It is proved that effective use of the switched reluctance motor on a rolling stock of the serious problem consisting available of significant forces of a one-way electromagnetic attraction, exceeding maximum permissible values. The methods of solution of this problem consist in tightening of manufacturing tolerances of SRM parts and assemblies or artificially introduced asymmetry of magnetizing forces.
