Abstract

A rotating electric machine rotor 10 includes a rotary shaft 11, a rotor core 12 fitted to the rotary shaft 3.1, and a plurality of slots 1.3 formed in an outer peripheral surface of the rotor core 12, the slots 13 each accommodating a rotor bar 14 and each extending in an axial direction of the rotor core 12. A ventilation groove 15 opening to a bottom portion of each of the,slots 13 is formed in the rotor core 12 so as to extend in a length direction of its corresponding slot 13. A plurality of ventilation holes 16 are formed in the rotor bar 14 such that one end each thereof faces the ventilation groove 15 and the other end each thereof communicates with an opening of the slot 13.
