| description | To provide a rotor of a rotary electric machine which can suppress cracking of a core.SOLUTION: A rotor core 21 is formed by laminating electromagnetic steel sheets 22. The rotor core 21 is formed with an outer diameter side permanent magnet insertion hole 24 extending axially and arranged radially outside, and an inner permanent magnet insertion hole 25 extending axially and arranged on the inner diameter side of the outer diameter side permanent magnet insertion hole 24, for each magnetic pole. An outer diameter side permanent magnet 26 divided in the axial direction is inserted into the outer diameter side permanent magnet insertion hole 24, and an inner diameter side permanent magnet 30 divided in the axial direction is inserted into the inner diameter side permanent magnet insertion hole 25. A magnet dividing surface 29 of the outer diameter side permanent magnet 26 and a magnet dividing surface 33 of the inner diameter side permanent magnet 30 are displaced from each other in the axial direction.SELECTED DRAWING: Figure 6
【課題】ロータコアの割れを抑制することができる回転電機のロータを提供する。【解決手段】ロータコア２１は、電磁鋼板２２を積層して構成されている。ロータコア２１には、軸方向に延びるとともに径方向外側に配置される外径側永久磁石挿入孔２４と、軸方向に延びるとともに外径側永久磁石挿入孔２４よりも内径側に配置される内径側永久磁石挿入孔２５とが磁極ごとに形成されている。外径側永久磁石挿入孔２４に軸方向において分割した外径側永久磁石２６が挿入されるとともに内径側永久磁石挿入孔２５に軸方向において分割した内径側永久磁石３０が挿入されている。外径側永久磁石２６の磁石分割面２９と、内径側永久磁石３０の磁石分割面３３とが、軸方向においてずらされている。【選択図】図６ |
