Abstract

　コギングを低減できるリニアモータを提供する。 　リニアモータは、Ｎ極とＳ極が交互に形成されるように複数の永久磁石２１が並べられる界磁部５と、界磁部５に対向して配置される複数の突極１４ａ，１４ｂ，１４ｃを有するコア１４と、コア１４の複数の突極１４ａ，１４ｂ，１４ｃに巻かれる三相コイル１６と、を備える。三相コイル１６とコア１４とからなる電機子１０の移動方向の両側には、電機子１０を挟むように磁性体からなる補助コア１８が設けられる。補助コア１８の中心から中央突極１４ｂの中心までの距離Ｐ１が、界磁部５のＮ極－Ｎ極間の磁極ピッチの実質的に１／４×（２Ｎ＋１）倍（Ｎ：１以上の正の整数）に設定される。
