Q:Why do most fans only have 3 blades?
We usually use the fan for axial fan, the blade is odd, this is because if the even shape symmetrical blades, and no adjustment of balance, it is easy to make the system resonance occurs, if the blade material is unable to resist fatigue due to vibration, will cause the blade or the spindle is broken, so odd pieces of the fan blade design on asymmetric multi axis design
