摘要： This electric fan has a rotation shaft that is provided rotatably with respect to a stator, a rotor yoke provided on the rotation shaft and formed in a bottomed cylindrical shape so as to cover the stator from a front surface, and a bracket that fixes the stator to a fan shroud and is formed so as to cover a rear surface of the stator, with a fan body provided so as to integrally rotate with the rotation shaft and the rotor yoke. The fan body has a fan boss formed in a bottomed cylindrical shape so as to cover the rotor yoke from a front surface, and a plurality of blades that is provided protruding radially from an outer circumferential surface of the fan boss. A first labyrinth portion is provided between an opening portion of the fan boss and the fan shroud.
摘要翻译：该电动风扇具有相对于定子可旋转地设置的旋转轴，设置在旋转轴上并形成为有底圆筒形以便从前表面覆盖定子的转子轭，以及将定子形成为覆盖定子的后表面的风扇罩，其设置为与旋转轴和转子轭一体地旋转。风扇主体具有形成为有底圆筒形状的风扇凸起，以从前表面覆盖转子磁轭，以及从风扇凸台的外周表面径向设置的多个叶片。第一迷宫部分设置在风扇凸台的开口部分和风扇罩之间。
