Abstract

　ステータは２つの磁気軸受部の間にモータ部を挟着し、ロータの側面に所定の間隔を設けて磁気軸受部を構成する磁気軸受ヨークを等間隔に円周状に配設し、磁気軸受ヨークにはロータの側面に対向する２つの突極を備え、一方の突極に磁気軸受用コイルを巻着し、他方の突極に第１永久磁石を設け、モータ部側に設けられた突極とモータ部のモータヨークとの間に第２永久磁石を設け、一方の磁気軸受部のモータ部側に設ける突極を全てを、磁気軸受用コイルを巻着した突極にするか、あるいは第１永久磁石を設けた突極にし、他方の磁気軸受部のモータ部側に設ける突極全てを、磁気軸受用コイルを巻着した突極にするか、あるいは第１永久磁石を設けた突極にする磁気浮上モータである。
