Abstract
2つのV字形に配列された磁石穴の上端面と回転子の外周部間に形成された鉄心部にて、q軸磁束の飽和を抑え、リラクタンストルクの利用と、磁石トルクの向上を図り、起動時や急激な負荷変動に大きなトルクを得ることができ効率が良い、電磁鋼板形成体、電磁鋼板積層体、これを備えた永久磁石形同期回転電機用回転子、永久磁石形同期回転電機、該回転電機を用いた車両、昇降機、流体機械、加工機を提供する。
回転子コア(11)における所定の極ピッチ角(θ)で設けた放射状の極ピッチ線(OP)の範囲内に、V字に沿って1極に対する永久磁石(6)、(7)を2個挿入するための2個の磁石穴(2)、(3)のうち、一方の磁石穴2を該極ピッチ線(OP)の中心線(OC)から遠ざかる方向にずらし、他方を該極ピッチ線(OP)の中心線(OC)に近づく方向にずらして設ける。
