配置されて所定のタイミングで励磁方向が反転さ
れるステータと、前記ロータの外周部に設けられ
た被検出素子と、この被検出素子を検出するよう
に固定配置された検出素子とを備え、前記被検出
素子の前記検出素子による検出タイミングに基づ
いて前記ステータの励磁反転タイミングを決定す
るブラシレスＤＣモータにおいて、前記ロータの

けたことを特徴とするブラシレスＤＣモータ。 A rotor consisting of a permanent magnet, a stator disposed opposite to the rotor and whose excitation direction is reversed at a predetermined timing, a detected element provided on the outer periphery of the rotor, and a stator configured to detect the detected element. In the brushless DC motor, the brushless DC motor includes a fixedly arranged detection element, and determines excitation reversal timing of the stator based on the detection timing of the detection element by the detection element. A brushless DC motor, comprising a moving means for mechanically moving the rotor in the rotational direction of the rotor.
