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鐘旋轉的次數，單位是rpm。風扇轉速由電機內線圈的匝數、工作電壓、風扇扇葉的數量、傾角、高度、直徑和軸承系統共同決定。轉速和風扇質量沒有必然的聯系。風扇的轉速可以……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.
