Abstract

　本発明は、高い生産性を有する界磁子である。界磁子（１）は、界磁コア（２）と、界磁磁石（５）とを備えている。界磁磁石（５）は例えば二つの永久磁石（５１，５２）より構成されており、界磁磁石（５）の幅は中央から両端に向かうに従って単調非減少で増大している。界磁磁石（５）は、その両端に回転軸Ｐとは反対側に突出する突部（５１ａ，５２ａ）を有している。界磁コア（２）には、界磁磁石（５）が貫挿される貫挿孔（４）が設けられている。貫挿孔（４）は界磁磁石（５）の磁極面（５ａ，５ｂ）をそれぞれ覆う貫挿面（４ａ，４ｂ）を有している。具体的には、貫挿面（４ｂ）は突部（５１ａ，５２ａ）と嵌合する凹部（４１ａ，４１ｂ）を有している。そして、界磁磁石（５）を挿入するに際して、貫挿面（４ａ，４ｂ）は界磁磁石（５）を導くガイドとして機能するので、容易に界磁磁石（５）を貫挿孔（４）に貫挿することができる。
