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...

風扇轉速是指風扇扇葉每分鍾旋轉的(Of)次數，單位是rpm。風扇轉速由電機内線圈的(Of)匝數、工作(Do)電壓、風扇扇葉的(Of)數量、傾角、高度、直徑和(And)軸承系統共同決定。轉速和(And)風扇質量沒有必然的(Of)聯系。風扇的(Of)轉速可以(By)……enen

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 is acceptable.
