As the voltage goes up, the arc gets longer, until it can bridge the gap between opposite sides. All power then goes through the arc, it becomes a carbon arc lamp, and quickly burns up the carbon rods. Rapidly disintegrating carbon also sticks to the commutator helping to bridge the arc around to the other side. The big generator has better reaction-force spring brushes. It probably took this abuse with no damage at all.
It isn’t that fast; the limit on motors of these are 377mph-559mph. Of course these people are forcing it to max. But just bc it is max doesn’t mean it isn’t harmful to itself, but people thought it would do vvvveeerrryy little to no harm at all.
That first one... Holy fucking shit fucker, sounded like a goddamn jet spinning up, Put a damn propeller on that thing and you could probably fly a fricken house!
These perfectly working motors could have been sent to less fortunate countries like the United States. But blowing up in the name of science is much more worthy.
Many of these experiments are actually illegal in the former Soviet republic of Motoristan; motor worship is the official state religion there. They even have a dishwasher motor on their flag.
This can make a cool episode in some car chase, where the hero turns the engine of his electric car to the overdrive mode and seeing it literally burn, but still providing power to escape (or catch up). Also, internal combustion engines don't fail that spectacularly.
Yeah, internal combustion engines just kinda chuck parts through the block (usually a connecting rod or piston) but electric motors not only sound like jet engines but they actually explode in a rain of sparks and bullshit!
What I'm curious about is how in the hell did you get that huge generator up there? Unless this is in another room of course, but damn, those are some spectacular burnouts, I had to watch it twice!
i love all these vids, there is one thing yet to be seen on RU-vid: a motor disintegrating by true rotational forces - the common mode of failure seen so far seems to be a combo of commutator/winding overheat.
Wow, red stinking hot commutator bars! Good job, the builders, balancing those armatures so well that they can spool up way past their designed rpms without dancing across the floor.
Well i enjoyed watching this man did them motor's hit some SERIOUS RPM,LOL they were cooking and on fire AWESOME i love stuff like this i say thank god for people doing stuff like this it is what make's life interesting sound's like a jet,lol WE HAVE LIFTOFF.
