Abstract
固定子鉄心（6）と、固定子鉄心（6）に設けられる電機子卷線（8）とを有する固定子（2）と、回転子鉄心（12）と、回転子鉄心（12）に埋設される、回転子（3）の極数分の永久磁石（14）とを有し、空隙を介して固定子（2）と対向する回転子（3）と、を備える永久磁石式回転電機を提供する。永久磁石式回転電機では永久磁石（14）の磁束軸をd軸、d軸と電気角で直交する軸をq軸とし、回転子鉄心（12）はq軸上において内周側に凹む凹部（11）を有し、凹部（11）は、永久磁石（14）の厚み方向に沿う二つの直線部（11b, 11c）と、二つの直線部（11b, 11c）の回転子内周側の各端部に接続する曲線部（11a）とから構成される。永久磁石（14）の外周側の磁極面の端部間の角度（θp1）と、二つの直線部（11b, 11c）の回転子外周側の各端部間の角度（θp2）とが、0.18 ≤ θp2/θp1 ≤ 0.5となる関係を有する。永久磁石式回転電機は、高速域においても高トルクを出力できる。また当該永久磁石式回転電機を用いる圧縮機を提供する。
