Abstract

　マグネットロータと、ステータコアと、モータコイル５とを有する単相ＤＣブラシレスモータを駆動する単相ＤＣブラシレスモータの駆動装置であって、マグネットロータの磁極位置を検出する磁極位置検出センサ６ａ，６ｂと、モータコイルに接続されたスイッチング素子３ａ，３ｂ，４ａおよび４ｂと、磁極位置検出センサから出力される磁極位置検出信号に基づき、スイッチング素子をオンまたはオフ制御してモータコイルを通電または非通電状態とする制御回路７とを有し、制御回路７によりステータコアと対向するマグネットロータの表面磁束密度の変化率の絶対値が所定範囲内にあるとき、モータコイルを非通電状態とし、簡素な回路構成で単相ＤＣブラシレスモータの効率を向上させることを特徴とする。
