Amazing and inspiring work Professor Laimer, you're gathering a lot of students, like me, with your videos and creations!
I'm FDM printing impellers for home appliances development for 5 years, but never went over 20.000 rpm.
I suggest you to put this in a precise balancer, it makes a huge difference in performance and reliability.
why would you want to spin a motor 20,000 rpm.. you want 500 rpm with a bigger prop
@@johnnyllooddte3415 Higher aspect ratio is always more efficient. But in my case I had limited space to work with (home appliance development) so I had to use higher rpm to reach my target air flow
This is awesome. Congratulations.
Finally we can take over lockheed martin
very inspiring work professor. greeting from malaysia.
Молодец дядька)
I'm definitely building one
Awesome.
Wow .... great!!!
Nice 1
what is the efficiency/ power increase between this and a regular brushless motor? would love to see you make another motor the same size without the array to compare.
yeah you wont be catching me standing on the side of a spinning assembly.
Axial is also not very safe.
Why is it not safe?
Because those are 2 main ways in which shrapnel will go.
Absolutely
Two words.. Final Destination!! Imagine tripping over something and face planting into that thing.
Could you do a video showing how you did the wiring connecting to the ESC and etc?
would love to see one of these on an RC plane.
How would you go about determining the duty cycle of this motor? Have you had any failures due to heat/vibration? Also, amazing work! Inspiring!
one flite at flight test before burning up
Man, really... You are nuts...
Standing so close to a spinning motor that wobbles like this one does.
If a blade brakes from the propeller you could loose a limp or worst.
Nice content, but I would have loved it even as much if the camera would have been placed on a tripod and you were controlling the motor from a save distance.
Before taking this video, I've done a test from a safe distance with higher RPM ... ;-)
do you think that you could stiffen the axle and get less "wobble" from the propeller ?
Actually the motor shaft itself isn't wobbling at all. It's the propeller mount and the spinner which are not perfectly aligned mounted on the shaft. Here you can see the motor running without the propeller: ruclips.net/video/NFvMC3l3fGY/видео.html
Christoph, excellent work!! It is very clear to see that it is the propeller nose is not aligned and not the shaft. More importantly, the propeller is putting a high load on the shaft, so wobble would be only a small factor. If you take a look at the video he made where he pushed a motor to 30,000 RPM, you will see that he is using a very large safety factor. So, I think he knows his limits and he is documenting them very well.
yes my thoughts exactly..this is why he probably hasnt posted in 3 years from the hospital
This is insane!
It this motor compatible with electrobikes?
can wait to see parts of the assembly delaminate and see stuffs flying around.
I'm attempting to do something similar for a hub motor in an electric vehicle. Is it possible to tune the array for max torque or efficiency at about 1000 rpm?
I’m wandering how heavy was the weight that the motor could not move it. It would be a good indicator of how heavy the pusher drone could be (all other factors considered).
Make a plane with that.
Hello,very nice design. Wonder what the parameters od this stepper motor are. Whot is the trust at whot current. Whot is the maxsimum engine trust at which RPM? GREETINGS.
Hi Christoph! Curious if you can tell us the diameter/pitch of the prop? Thanks!
14 x 8 inch, spinning backwards
I really wonder how powerful it would be with a metal stator core that is magnetic.
Which battery and motor is suitable for 120 A esc?
Have you tried putting a strain gauge on the motor housing? Would be interesting to see
:-) ... It would twist the data wires quite rapidly. Certainly an interesting project to do something wireless with an Arduino.
A small esp 8266 should do nicely. Small. Built in WiFi.
How strong are your magnets ?
It's is best
Question could you do a Test too see how long this motor last tell it over heats
??? it lasted one flit before burning up
What amperage esc are you using
The ESC supports 100A. That's overkill, 30..50A would be enough.
3d- Files link is broken can you update it please ?
what is the thrust of your motor with this particular config ?
my question exactly
??? it lasted one flite before burning up
Battery voltage?
Plane?
what is the thrust
He made a video in which he fully explains everything.
@@paulhendrix8599 no he didnt explain the thrust
How long can it run before it melts?
??? it lasted one flit before burning up
@@johnnyllooddte3415
A whole flit? Impressive!
what about the heat?
Depending on filament it may actually be able to handle the amount of heat that is generated by the centrical force of the motor and coils inducional impedence
@@vegas6669 ??? it lasted one flite before burning up
aint no halbach girl
how much thrust please
from wear ware you
