Motor commutator arcing at 10,000fps

[xmodalloy]

So, why don't they slant the brushes to have only one point of contact to the commutator when it first arcs? Or would that just make things worse? Seems like it might be worth experimentation.

It's over 9000

[rocketman221projects]

Cool. What camera are you using? Thats a very good picture at such a high frame rate.

[BarneySaysHi]

Amazing video, thanks!

[superdau]

Wow, very nice! For some time of the spin up the music was also in sync with the sparks ;)

Btw. it looked as it was always the same gap that drew arcs (it has a dark spot below the contacts).

[thewii552]

any chance you could release the camera project?

[tesla500]

@thewii552 I could release the first camera I built awhile back, that's the only one that's in a usable state at the moment. Let me set up somewhere to upload it to.

[RODALCO2007]

That is an awesome video. Top quality camera you have there.

Interesting to see the arc between two of the segments staying in tact, obviously faulty winding or carbon dust build up.

[wcocowcocow]

honestly that is the most awesome thing iv ever seen.

[digihawk159]

How many volts did you use to make it do that? I happen to have the same motor, and want to do something similar. Any suggestions?

[anthonyj777]

Hi very impressive setup there, I'm confused though; I thought the CCD you were using was only capable of 320x240 @ 940fps ? the video look to be a far hight resolution and you say 10,000 FPS?

[tesla500]

@anthonyj777 This is the new camera, which is about 10x faster than the old one. I posted a video a week or two ago showing the new camera.

[anthonyj777]

@tesla500 Ah right, will check out the video, only just found your channel.

Wow, is all I can say about the camera!, well done:)

[ninjaspeak]

What song is that?

Love the videos by the way. Your love of destruction reminds me of the Mythbusters.

[tesla500]

@ninjaspeak Thanks! The song is Plunge into Hyperreality by JT Bruce

[Garcansdad]

Great video! Even the music is just about in perfect sync. Tell Photonicinduction he needs a camera like that to record his destructive exploits!

[tesla500]

@Garcansdad Thanks! I swear I didn't even try to sync it up, I was astonished how well the music just happened to line up.

[thegamer589]

can i ask wear can i get a camera like that

[tesla500]

@thegamer589 Companies such as Vision Research, NAC, and Redlake sell them, however a camera like this costs about $40k. Hence why I'm building one instead of buying.

[MrTurboturbine]

Nice! one of the best high speed shots yet!

now just connect the power to the brushes and crank it till it pops :)

[tesla500]

@MrTurboturbine I'll have to find a junk motor to try this with. It would be very interesting to see arcs connecting all the comm bars (and therefore shorting the mains!).

[bkraz333]

You could do some serious original research with that camera. Great job!

[douro20]

I've cleaned up some universal motors a few years ago, and I found that cup leathers work really well to clean up the bars on the commutator.

[colt4547]

Fantastic video! That is one of the most interesting videos I have ever seen on youtube.

[marcelh85]

Verry interesting! keep up the good work

[Aussie50]

Really interesting indeed!. great video!.

I wonder if the camera would handle the arc light from a Universal Motor running off a MOT :D

[tesla500]

@Aussie50 Thanks!

I've gotta try that with the 10 MOT resonant setup. I can crank the exposure down as low as 2us, so hopefully too much light won't be a problem!

I wonder if a vacuum cleaner blower can break the sound barrier?

[Geoffr524]

Awesome lesson, how armatures behave.
