Abstract. The paper presents a possible application of the magnetorheological suspension (MRS) to DC electrical machines. The MRS, obtained by thermal decomposition of Fe2(CO)9 in mineral oil, consists of iron particles (with diameters ranging between 0.6m and 1.9m) and technical saturation magnetization of 496kA/m – at H=1,050kA/m, is located between the stator and the rotor (of a d.c. current generator – type U9M4/U6T). The electric power supplied to a non-reactive load, as a function of number of rotations per unit time is measured. It is shown that the utilization of the MRS considerably enhances the output power of the generator.
