Abstract

ｎ相（ｎは正の整数）のブラシレスモータ装置において、ステータ１４と、所定の極数を有するロータ１２と、ロータの回転軸に直交する面に固着され、該ロータの２倍の極数を有する磁極位置検出用マグネット１６と、磁極位置検出用マグネットに対向するように配置されてロータの磁極位置を検出するｎ個のメインホール素子１８ａと、メインホール素子に対して周方向に所定のオフセットを有するように配置されてロータの磁極位置を検出するｎ個のサブホール素子１８ｂと、メインホール素子の出力パターンの変化に応じて「２」をカウントし、所定タイミングでメインホール素子の出力パターンとサブホール素子の出力パターンとが同じである場合に「１」をカウントし、これらカウントされた値に応じてロータの回転を制御する制御部を備えている。
