AEO 40mm 8 blade FAN--over 400 watts!

I had gotten a box of small EDF fans from AEO a few weeks back to see which of our Neu motors would fit and work in the different fans. I have the 30,40,65 and 70 mm 8 blade fans all without motors.

Yesterday evening i installed a one of the Neutron 0707 motors in the 40mm size AEO fan. After starting out at 10 volts we kept pushing up the voltage to see where things would go. When we got to 75,000 RPM and 400 watts it seemed like a good point to stop for the evening. It did not show any signs of distress--motor was only a little warm from. I am not too sure where the blades will be depart the fan but it looks like the setup could top 500 watts for short periods and not hurt the motor.

Now to find a clean model to put it in....

Steve,

Are these fans available to the public yet (to your knowledge)? Thanks.

I had no trouble getting them. If there is interest I can carry them.

Wow, what in the world does an EDF40 sound like spinning at 75k? Did you notice what the amp draw was at the 400w mark? I'm guessing it was around 25a? GWS was getting close to 400w on the GWS EDF40 with the 2018 motor in testing, but there was a high rate of motor failures. Would be great if your motors can handle it

It was about 20 volts and 22 amps --from the power supply settings. I am thinking that a higher Kv motor might be good so it would hit 400+ watts on 4S.

The sound does get your attention

Plenty of projects ! Can you give the exact motor and EDF refences (+ kv, etc...) and where to get hem, please ? I'd like to purchase one set for an old project. Thanks !

What version of the 0707 were you using, Steve? A loaded rpm of 75000rpm @ 20v doesn't gel with the 3750Kv, nor the 4800Kv.... if it was ~4200Kv (not listed) that would fit.

setup could top 500 watts for short periods

Wow!!!!!

I was told it was too good to be true and there was no way a small motor could do this... Oh but wait that was a Chinese motor......

Sign me up, this is the GWS 20mm fan motor that they have been advertising.

I need to get me some of these.

Which one though that is the question?

500 watts Steve, is that for any of the 707's?

Where or how do we get a motor?

This is one of our motors--not Chinese. More testing and abuse is in the works --stay tuned.

You will need around 5800-6000Kv to get near 75K on 4 cells? Will be interesting to see what the amp draw goes to.
