Claims

[Scope of utility model registration request]

In a device in which a rotary persimmon is attached to a laminated iron core in which a core groove is formed, the laminated iron core is connected to a first laminated group in which a core groove of a normal width is formed, and a radial ventilation passage is formed in the core. A second laminated group with wide grooves is laminated in a predetermined arrangement, and a ventilation groove is formed along the axial direction on the side surface of the rotary dried persimmon in the rotation direction, and this ventilation groove and the second laminated group are A rotor for a rotating electric machine, characterized in that the radial ventilation passages of the wide part of the group are communicated with each other.
