The manufacturer of five blades solar powered electric fan tells you the number of fan blades. The number of blades of an axial flow fan is generally an odd number. This is because it is easier to correct the center of rotation when doing dynamic balance correction. The manufacturer of five blades solar powered electric fan tells you that if an even number of fan blades is used, the system will easily resonate. If the material of the blades cannot resist the fatigue caused by vibration, the blades or bearings will easily break, so the odd number of blades with asymmetric axes Fan blades are more suitable. The same principle applies to helicopter propellers.

The difference between a three-blade fan and a five-blade fan:
The manufacturer of five blades solar powered electric fan tells you that the single leaf area of the three-blade fan is larger than that of the five-blade, and the range of air action is also increased, which will produce greater noise; but the mold and production of the three-blade fan are compared with the five-blade The fan is much easier, the cost is lower, and the connection between the root of the blade and the central axis is wider, so the blades of the three-blade fan using the same material are much stronger than the blades of the five-blade fan. Therefore, generally speaking, fans with low noise are mostly five-bladed; and the wind power of five-bladed fans is relatively soft.
The manufacturer of five blades solar powered electric fan tells you that the original home fans are basically three-bladed, but now people are pursuing five-bladed fans such as silent and natural wind, and the price is relatively higher.
