FIELD: electrical equipment.
SUBSTANCE: invention relates to the field of electrical equipment and concerns the reactive rotor of an electrical machine. Rotor has layers of rotor sheets from ferromagnetic material, each of which has a flow barrier formed by a recess. In addition, the reactive rotor has an intermediate portion disposed between the rotor sheets first and second layers, having recesses and bridges delimiting these recesses. Recesses of the intermediate part and the bridges are located in the axial direction between the flow barriers, so that the recesses of the intermediate part and the flow barriers together limit some space. This space is flooded with a non-ferromagnetic casting mass.
EFFECT: ensuring the rotor stability to high torque and high speed.
