Testing a vacuum cleaner motor

[BoomBoxDeluxe]

WHAT?! We didn't get flames!

I'm disappointed.....where's my hammer?! :-D

Place the live wire on one brush, the neutral on the other brush, then turn up the variac.

Crank it up as hard as it goes until it pops. :-D I WANT FLAMES!!

[theperkule]

turn it on 999

[fredbrill1]

my on off switch won't stay "on" position...can u help

[gaypotter]

dont put your dick in that thing

[Bjumpje]

in the inside of the motor are flames



[RCPhilNX]

@Bjumpje where? This blinking are Sparks. Thats normal.

[lexichronicle2]

they can do a few tens of kRPM. The one in that tiny handheld dyson can manage 104kRPM, ya... rly...

Dental drills can go way up beyond that to insane RPMs

[frohman3]

I swear, I took out a motor from an old shop vac, and that thing is serious fast.

[mjf425]

mini jet engine awesome gotta have it lol nice vid man

[TheDidlo1]

Neat, I guess. The worlds fastes pencel sharpener. It could eat an entire penel as fast as you can push it in. Also eats pens, chop stix and cigarettes

[williamblake69]

niiiice ....... what is the thing you are twisting to controll the input voltage?

[omataqo123]

if i was to put it on a wheel how fast can it go?

[omataqo123]

this may sound stupid but which one is the motor? lol

[omataqo123]

Nvm this question

[infamoussafg]

@omataqo123 the red one with the clock on it

[compactc9]

no, the gray/silver thing to the right is.

[rhett443]

wow... im taking apart the old one in my garage and using this motor to power my Siren

[HappyDiscoDeath]

pulled an 840 watt motor out of an old Hoover 409 that's missing the wands and brushes. put it on the floor sideways, and it rolled away real fast before running out of wire! freaking awesome!

[Bigjohnnywad]

What uses could a old vacuum cleaner motor be used for? I have one in my house and am wondering.

[poortuber]

@Bigjohnnywad well it is a basic jet engine , all you need are a fan blade on the front , a cowling , and a combustion chamber to ignite the fuel , then strap it to a 12 volt car battery and lash it to a bike and you have a jet powered cycle . lol

[Emanuelcoco]

Fuck You stupid motor vacuum cleaner

[pitbike2006]

would a 3 amp variable autotransformer  work ? just for something like a motor in your video ? free running

[DocterrNick]

could you use the motor on a go kart?

[Laakkonen1]

no. it delivers only few hundred watts and it needs pretty high voltage to give enough power.

[cutty02]

@Laakkonen1 a few hundred? 8A @ 120v = 960 watts that is 1.3 HP that should be enough to get you going at least 20mph with the right gearing.

[fairyheli2]

@DocterrNick no, but imagine this on a bicycle

[Helicopterpilot16]

How much did the variable autotransformer cost you, I've seen a couple on ebay for $45. this is what I,ve wanted to do!

[Laakkonen1]

0eur/0usd. 8A 230V.

[dellone13]

were you using a speed controller on the motor?

or what?

and where did you get it?

[Laakkonen1]

I used a variac, variable autotransformer. Varying the voltage caused the speed to vary. One classmate gave me that motor, probably she disassembled it from her old vacuum cleaner (she bought new one recently :).

[NathanH5]

Was the motor free-running, or was it spinning the vacuum fan? If free-running, it should surpass 20,000 rpm.

[Laakkonen1]

Fan was mounted. I'm gonna disassemble it and use the motor as ARSG's motor.

[Latias82]

Nice vid. How high could you go before you start to exceed the motor's limitations?

[Laakkonen1]

Not very much over 230V. It's iron area and windings' thickness are seriously underrated. It blows the air through the motor and gets still warm/hot.

[Latias82]

Ok cool. Is it possible to get a vac motor working with just battery power, wired in series to increase voltage? Obviously the motor wouldn't turn very fast due to the weak voltage, but I'm just wondering.

[Laakkonen1]

Yes, these motors work on both AC and DC. There is a certain threshold voltage due to the commutator. As you can see, it spins pretty well even at 25V.

[twocvbloke]

What vacuum cleaner did the motor come from?

[Laakkonen1]

Probably Miele's, but I'm not sure because classmates gave that to me.
