Claims

[Scope of utility model registration request]

A rotor core consisting of a plurality of core blocks, in which a plurality of air holes are formed in these core blocks so that the number of air holes decreases from the end side toward the center, and this rotor core In a rotor of a rotating electrical machine, the rotor is provided between the iron core blocks and includes a connection member connecting the air holes located at opposing positions, wherein the ventilation area of each of the air holes is located at the center of the five iron cores in the radial direction. A rotor for a rotating electrical machine, characterized in that as the rotor approaches the rotor, the ventilation area becomes larger than the ventilation area of each air hole on the outside.
