Sure enough, testing was less than perfect. These things happen in R&D.
Once everything was hooked up and ready to go, we popped on the fan, and the entire product started shaking and screeching. Not exactly ideal.
Our first theory was a loose motor. Since it spins from 5000 to 10000 RPM, and delivers five to seven meters of air delivery, we can’t let even the slightest issue go unresolved.
Upon a closer look, this wasn’t the only issue.
We’re going to need to take a step back and modify the design, as well as run more calculations to ensure each component is the right fit.
It could be a complex set of problems, or just a poor installation of the motor. We hope it’s simple, but it’s worth investigating.
Take a look and hear it:
We've used a digital anemometer to measure the wind speed, not only it did not reach our expected wind speed, and it is making a lot of noise.
But after checking on it, we realized it is more than that.
We’ll need to go through the designs, do some more calculation to check what went wrong.
Perhaps checking all the components are in the correct spec.
Or, we just didn’t install it properly. Hopefully this is the main reason causing the crazy vibration and noise.
