PROBLEM TO BE SOLVED: To provide a rotor of a dynamo-electric machine capable of reliably cooling a permanent magnet while having a simple constitution.SOLUTION: A rotor 14 of a dynamo-electric machine includes a rotor core 20 and a plurality of permanent magnets 23 embedded in the rotor core 20. The plurality of permanent magnets 23 are fixed, with a fixing resin, within magnet holes formed in the rotor core 20. A part of the fixing resin projects from an end surface of the rotor core 20 in an axial direction to configure a guide wall 42A for guiding a flow of a refrigerant.SELECTED DRAWING: Figure 3 |
