The fan speed refers to the number of rotations per minute of the fan blade in rpm. The fan speed is determined by the number of turns in the coil, the working voltage, the number of fan blades, the inclination, the height, the diameter and the bearing system. There is no necessary relationship between speed and fan quality. The speed of the fan can be...

風扇轉速是指(zhi)風扇扇叶每分(fen)鐘旋轉的次数，采用rpm作為(wei)標準計量單位。这一轉速指標由(you)電機内線圈的匝数、工作電壓、風扇(shan)扇叶的数量(liang)、倾角、高度、直(zhi)径和轴承系統(tong)等多個因素共同決定，其中任何一個參数(shu)的改變都會對最終的運行效率產(chan)生影響。

Fan speed, quantified in revolutions per minute or rpm, constitutes a fundamental operational parameter that describes the rotational velocity at which fan blades complete their circular motion around the central axis. This performance metric emerges from the complex interplay of multiple design and engineering variables that collectively influence how rapidly a fan operates within its mechanical system.
