Title (EN) FAN, AND ROTATIONAL SPEED DETECTION METHOD
(FR) VENTILATEUR ET PROCÉDÉ DE DÉTECTION DE VITESSE DE ROTATION
(JA) ファン、回転数検出方法
Abstract:
(EN) A fan (10) rotates with a rotating shaft (30) to generate an air current. The fan is provided with: a plurality of blades (11) radially arranged about the axis (CL) of the rotating shaft; and a boss (13) for connecting the plurality of blades to the rotating shaft. The boss of the fan has an end surface (15) formed on one end side of the rotating shaft. The end surface is configured so that one circumferential part of an annular region (CR) concentric with the axis of the rotating shaft will have a different optical refractive index from the other circumferential part of the annular region.
(FR) L'invention concerne un ventilateur (10) qui tourne avec un arbre rotatif (30) pour générer un courant d'air. Le ventilateur comporte : une pluralité de pales (11) disposées radialement autour de l'axe (CL) de l'arbre rotatif ; et un bossage (13) pour relier la pluralité de pales à l'arbre rotatif. Le bossage du ventilateur comporte une surface d'extrémité (15) formée sur un côté d'extrémité de l'arbre rotatif. La surface d'extrémité est conçue de telle sorte qu'une partie circonférentielle d'une région annulaire (CR) concentrique avec l'axe de l'arbre rotatif aura un indice de réfraction optique différent de l'autre partie circonférentielle de la région annulaire.
(JA) ファン(10)は、回転軸(30)と共に回転することで気流を発生させるものである。ファンは、回転軸の軸心(CL)を中心に放射状に配設された複数のブレード(11)と、複数のブレードを回転軸に対して連結するボス部(13)と、を備えている。ファンのボス部は、回転軸の一端側に形成された端面部(15)を有している。そして、端面部は、回転軸の軸心と同心円となる円環状の領域(CR)における周方向の一領域が、円環状の領域における周方向の他領域に比して光の屈折率が異なるように構成されている。
