Abstract

　本発明は連結部での応力集中を緩和する界磁子である。界磁子用コア(1)は、界磁磁石貫通孔(41,42)と、連結部(11)とを備える。界磁磁石貫通孔(41,42)は、所定の方向(91)の周りで周方向(92)に環状に配置され、周方向(92)について隣接して対を成している。同じ対を成す界磁磁石貫通孔(41,42)はいずれも、所定の方向(91)から見て、対毎に定まるある一方向(94)に沿って延在する。連結部１１は、同じ対を成す界磁磁石貫通孔(41,42)の間に設けられ、端(412,422)をそれぞれ側面(111,112)として有する。連結部(11)の側面(111,112)は、全体が凹に湾曲している。具体的には、所定の方向(91)から見て、側面(111)の両端の間のある一つの位置(r13)でのみ、側面(111)の接線(t（r13）)が、連結部(11)の延在方向(93)に沿う。側面(112)についても同様である。
