Claims

[Scope of utility model registration request]

A plurality of axial coil slots are provided on the outer circumferential surface of the cylindrical rotor core, and sub-slots narrower than the coil slots are provided at the bottom of the coil slots. A plurality of radial ventilation holes are formed in the coil, insulator, and wedge at intervals in the axial direction, and cooling gas is introduced from the sub-slots, and the rotation of the rotating electric machine is performed by branching the ventilation into the ventilation holes in the radial direction. 1. A rotor for a rotating electric machine, characterized in that a sub-slot is provided with a partition member that divides ventilation into a radial ventilation hole near an end of the core and a radial ventilation hole closer to the center of the core. 1
