How to optimize the size of the impeller and the selection of the motor according to the volume of the air, I need to design according to some known quantities, and I hope to have more professional people to answer
For the selection of impeller and the size of the motor, you need to see the specific volume, normally you have to consider an air volume and pressure balance, then up to select motor power and speed, in the same size, and the number of leaves and the width of the wind wheel are influential, so this requires you provide is not clear, can not give you the right reference
At present, most of the domestic fans are the products of the unified design in the 50s of last century. They have low energy efficiency and great noise. So there's a lot of potential for energy savings here. Energy saving 10~30% is easy to do.
The key is to understand aerodynamics, and to design blades based on aerodynamic principles. The blade seems simple, so twist it, but how to twist it, there is knowledge inside.
The impeller of the fan seems very simple. Many farmers entrepreneurs believe that this thing is not just to get it out of flower, the product. Actually, there's a lot of learning in it.
