摘要：【課題】回転子鉄心の両端で排熱性が異なる場合において、回転子鉄心の軸方向温度を低減均一化させることが可能な永久磁石式電動機を得る。【解決手段】Si+Al含有量が小さい鋼板を成層形成した鋼板ブロック8b、鋼板ブロック8bの鋼板よりもSi+Al含有量が大きい鋼板を成層形成した鋼板ブロック8aがシャフト7の軸方向に組み合わされて回転子鉄心8が形成される。回転子鉄心8は、駆動時に高温化する領域に、熱伝導率が高い鋼板ブロック8bを配置し、残りの領域に熱伝導率が低い鋼板ブロック8aを配置する。回転子鉄心8の軸方向の温度分布(昇温傾向)が、中央を基点として両側で異なっている場合であっても、高温化する領域に鋼板ブロック8bを配置することで、回転子鉄心8の温度を低減するとともに軸方向に均一化できる。【選択図】図3
