PURPOSE:To absorb the uneven lamination thickness caused by the buckling phenomenon of the core in the vicinity of vanes by arranging the duct pieces which are radially provided on the entire periphery of both sides of the rotor core so that the duct pieces are not arranged on the side surface of the rotor in the extending direction and at the close proximity of each vane. CONSTITUTION:A plurality of duct pieces 5 are radially provided on the entire periphery of both side surfaces of the rotor core 3. The duct pieces 5 are not arranged on the side surfaces of the rotor core 3 in the extending direction and at the close proximity of each vane 3. Relief slots 14 are formed in the direction of the diameter between the side surface of the rotor core 3 and a rotor clamp 7. The compressing force of the rotor clamp 7 which compresses the rotor 3 from both sides toward the shaft is not directly applied to the part of the relief slots 14. |
