Claims

[Scope of utility model registration request]

In a device in which a rotary persimmon is attached to a laminated core in which core grooves are formed, the laminated core is connected to a first laminated group in which normal core grooves are formed, so that a radial ventilation passage is formed.
A second laminated layer with a wide iron core groove is laminated in a predetermined arrangement, and the rotating dried persimmon has a first notch that serves as a ventilation passage in the axial direction of one side surface in the direction of rotation. , a plurality of second notches are formed in communication with the first notch and the radial circumferential surface to serve as radial ventilation passages, and the first laminated group and the second layer of the rotary persimmon are connected to each other. A rotor for a rotating electric machine, characterized in that notches are arranged opposite each other.
