<p>PROBLEM TO BE SOLVED: To provide a rotor of rotating electrical machine capable of ensuring the strength of the rotor against thermal stress when fixing magnets with a molding material.SOLUTION: In a second core plate 41 formed with a cooling oil pass 53 in a bridge part 61, a resin mold 24 is not formed in a second magnet insertion hole 43. In a first core plate 31 formed with no cooling oil pass 53, a resin mold 24 is selectively formed in a first magnet insertion hole 33. With this, in the second core plate 41 formed with the oil coolant pass 53, even when the thickness of the bridge part 61 between the second magnet insertion hole 43 and the oil coolant pass 53 is thin, the bridge part 61 is prevented from being subjected to an excess thermal stress; and thus, the strength of the rotor is ensured.</p> |
