FIELD: electrical engineering.
SUBSTANCE: core plates are made in the area of internal diameter with slots concentric in relation to this diameter at least in two rows; at that there are at least two slots in each row and bridges between slots are located in the middle of slots in the next row; at that joining of elements fixing core ends to the shaft is made at radial depth from the first row of concentric slots and joining of axial fixing elements to core ends is spread in radial direction to the shaft not farther then the last row of slots from the shaft.
EFFECT: prevention of impact of unevenly compacted rotor core on the rotor shaft of an electrical machine.
