I can see why. Paranoid of it shredding apart like they did with CD's sending shrapnel flying everywhere. This is a metal disc we're talking about. It is much more deadly than a plastic CD!
I did this expierement. Small 4 pole motor. Nominal speed is 1500 rpm on 50 hz. With vfd on 220 hz and 7000 rpm, torque so low. Rpm go down becouse motor cant spin its own blower
Lesson learnt: use steel brushes if you are overvolting your brushed mother. They lasted longer, just beware of the molten steel flying everywhere. :^)
Thank God, Finally the Video I Wanted Came. I Do These Kinds of Experiments All the Time. I Like Burning Small Engines. Where Did You Get the 400-500 Volt Supply? I'm Waiting for More Videos Like This
I guess some of the RPM's only mention what you attach, not what the motor is actually capable of spinning at given the proper voltage. Some operate just fine at 300 volts, others struggle and die after the 250 volt mark and end in fire. :D
can anyone explain to me why the amps go up too when increasing the voltage? In electric cars, if I have a full battery, the motor gets more volts, less amps and with an almost empty battery the motor gets way less volts, but much more amps (at least for a short time until the BMS caps the amps drawn.) Cars with an 800 Volt system do use only half the amps as compared to the same model on an 400V system. But with half the Amps, the losses of the engine are only 1/4. But in all cases, the motor uses the same energy, but just adjusts amps to hold its target power / target rpm in comparison to the voltage available... Why the heck to all those tools spin until doom and just increase the amps drawn even if the voltage is risen?
because if you increase the load of the motor the amps will increase in a higher rate too. you can see that current draw is steady until comes the overvolt and the motor rpm doesn't climb as fast as he can. that's when the motor needs more current to keep it turning.
I was expecting those angle grinder discs to fail and cause mayhem
i watched this with safety glasses on
i watched the grinder squinting like i always tend to do 😅
@@casemodder89 do you expect the blade just throwingn out of your device intno yor face
@@MrCoolOfficialYT a man who squints at angle grinders is a fool on all days except one
@MrCoolOfficialYT you literally wear safety glasses in your profile pic :^)
Those angle grinders made me really anxious.
Haven't had any accidents myself, BUT I keep thinking of it as ANKLE Grinder,
Because angle sounds like ankle (yikes).
I chuckled when the rev meter started creeping away😂😂😂

here’s me watching motors die on a Thursday night with nothing else to do 😂
same how
Literally me right now.

The Biltema "dremel" tool DID make it's speced top speed....At 430 volts! LOL.
there was something not right about tha one. something dragging probably the bearings
It was 420 volts so 🌿
I thought the reader just looped around whenever it hit its top amount. Like it would actually be 130000 rpm
i want to see this with induction motors & a VFD, and incrementing the frequency until they burn up, that would be insanely funny.
Yeah that's on my to-do list, but it looks like I have to build my own VFD... Or do you have any suggestion on a suitable pre-built one?
@@Cskirt They do exist, Zuked has them on Aliexpress. But only 2.2kw.
I've tried this but the electromagnetic field collapses around 3 a 4 times the frequency, so above like 160hz the motor only spins down
I did this expierement. Small 4 pole motor. Nominal speed is 1500 rpm on 50 hz. With vfd on 220 hz and 7000 rpm, torque so low. Rpm go down becouse motor cant spin its own blower
Vfd cand produce so high voltage need for this frequency. For 87 hz need 380v insteed 220 for 50. And how voltage need for 200hz and same torque?))))
This is wildly satisfying and cool to watch what happens at such absurd levels
Your pfp sexy :3
1:25 The 1.9 PD TDI in the work van on a cold winter morning..
The cutting wheels seem to have a much better tolerance beyond their ranges than the grinders 😂
Holy moly that impact gave me welders flash😂
Same

7:19 V8 POWER BABY
Awesome video! Subscribed
1:50 THIS PART SOUNDS LIKE A CAR AND I LOVE IT
Man seeing those grinder discs spin like that made me have flashbacks of when one exploded on me
I knew exactly what to expect with the steel "brush" on that impact but still gagged when I heard that startup
230mm grinder accelerated to a speed of ~650 km/h ☠️🌚
4:09 make a wish! Happy birthday to you! 😅
Must have been an expensive video to make 😶
All my videos are expensive 😅, this wasn't too bad, mostly old used corded tools no one wants
@@CskirtAre you from scandinavia? I recognized the Biltema logo :o
@@kraəb it literally says Sweden when you click on the channel description.
@@VIPPotato Oh, well i didn't see that. Thanks!
In the day and age of lithium and brushless tools, you can often find corded tools in the trash or at the flea market for a couple bucks per lol.
1:30 Starting Up
Getting into Photonicinduction territory, I see.
I wish photonicinduction was still active 😢
Need to do it again but with brushless power tools
Liked, subbed, and lifetime follower before watching. This is home.
When you were testing out the Black and Decker and DeWalt angle grinders, I was expecting them to surpass their exceeded limits, and they sure did.
That DeWalt was especially impressive wow.
Free advertisement right there
These power tools are universal motor can run at DC and burnout way more powerful! I recommand try this next time!
bro took "playing with electricity" to a whole new level
Awesome! Keep up the good work! 😊
6:19 I’ve seen car engines fail less violently than that angle grinder. Holy fuck
Thank God, Finally the Video I Wanted Came. I Do These Kinds of Experiments All the Time. I Like Burning Small Engines. Where Did You Get the 400-500 Volt Supply? I'm Waiting for More Videos Like This
I bought it used, 3-phase variable transformer with overdrive
impact wrench was traveling to the future for a moment
Photonicinduction would be so proud :D
If he'll be ever back
5:00 so this is what my friend should've done to get that rusty exhaust bolt off 😂
Thank you for using your electricity bill just for us to see this kool experiment
Ahh, asmr to my ears🥰
Good god that’s some serious voltage
The black & Decker sounded like one of the old original series startrek warp drives starting up.
Pneumatic tools can do that type of rpm all day long 😎
this is giving me anxiety, yet I still watch it
Awesome video
5:20 thanks ❤❤❤
?
Well that settles it- I’m upgrading all of my corded tools to steel brushes
The impact wrench became a jackhammer 😂
6:28 very thanks!!
Nihayet gelebildin😍 uzun zamandır video çekmiyordu İnşallah en kısa sürede kanalında yeni videolarda görmüş oluruz Sevgilerimle❤ sana iletiyorum
I would have loved to see the hammers of the impact wrench after destroying the motors! Surely they have taken a lot of damage too!
this guy's neighbors must love him
443V to fail that old school saw, old tools were incredible lol
1:36 started sounding like a diesel engine or something like that
😂😂
That’s true, it did
2 stroke lawnmower
What power company you got there? Mine got my TV, speakers, PC PSU, washing machine and water heater shot after releasing three-phase current
3:20 holy shii that needs an epeleptic warning😂
Just FYI that grinder wheel was going 226 MPH 🤯
That's fine, battlebots are allowed up to 250mph tip speeds
Oh jeeeeeeeeeezus
Good vídeo!!!🎉
Happy new years
3:57 Holy shi- fire
That circular saw looked like it hit 88 mph!
I put my face shield on watching this at 4:34
The last one sounds like a jet engine starting up
bro the angle grinders caused me anxiety and i wasn't even remotely close to them
What kind of power supply are you using to blow these things up!?
I guess some of the RPM's only mention what you attach, not what the motor is actually capable of spinning at given the proper voltage. Some operate just fine at 300 volts, others struggle and die after the 250 volt mark and end in fire. :D
Missed opportunity to hit those grinders with ammer.
The motors with lights out @@ be cool
The motor:💥🥵☠️
The flux capacitor was going strong with these tools... They'll wonder where all the power tools came from back in 1955.
Biltema 💪🏻💪🏻😂😂😂
Hold on but I need to know if the impact tightened the bolt! :(
It stripped the threads, can't get it out anymore 😭
Next *Makita Mitre Saw Ls1040*
Imagine drilling materials at 30.000rpm
You'll probably drill a concrete in like 1 second
Yep, now I want to see someone actually do it.
Did the commutator explode on the black and decker grinder?
Just a idea: try overvolting cheap kitchen ware😂 like blenders and dough machine's or water cookers😮
He did tho
1:29 Engine motor start
I was scared that the circular saw was going to fly out.
This cats must be the masters of stare, especially the yellow one. He's the cutest. 😢
6:02 the jet engine is starting up
5:43 sounds like a supercharger
Aww popped iiittt!
Huh, I could smell that first one
Rotary tool: **says 35k rpm**
Also rotary tool: **barely can handle the 35k rpm**
It made one last attempt and hit 35k before popping. That's how they rated it lol
@RennieAsh No wonder my CD says 25k rpm
Good old "Meec" tools.....
What you had a biltema powertool are you uropean?
Yes, swedish
IKEA Swedish meatballs😂
I can smell the burnt motors from here.
how about one of those kids cars that kids can drive. how fast can it go with high voltage.
Bro's making mini tokamaks at home
Woah
Lets go a new video!
all gas no brakes
At last the third grinder sounded like a 2 stroke

1:27 Sounds familiar...
The dewalt grinder desperately trying to keep going even as it occasionally spat out bits of itself
1:35 a generator?
5:09 Is that funhy?
After 400v all tools are welders. 😮
Your check motor lights are on
The 2nd one 😂
Bro tryna create time machine
i like my tools sparky bro
Why mans live so short?
Mans:
4:57 My switch
Anything can become a DeLorean if you add enough voltage.
