Hey guys.
Got this motor here... What do you think it's voltage is?
Tryed 12v, didn't even move...

Have you measured the resistance of the coils yet?
It seems to be dead if 12 V doesn't jerk it.
Could either be worn brushes or burned coils.

Not really... I don't know what resistance to except so I could compare... care to give some tips @PonySlaystation?

I'm going to lean out of a window here and say that motor's from a hair dryer. Why? Because it seems to have some residual hair wrapped around its shaft, which looks like it was build for pressure-fitting/molding into a plastic part (the propeller). That means it was probably built for mains.

Please don't just connect it to mains, though. In the case I'm wrong that would be really dangerous and even if I'm not, the insulation probably isn't built for it to be safe to touch. Also, it might have been connected to some tap of the heater and was actually running at a lower voltage.

If you really want to run it, use an isolation transformer and a variac.

@GyroGearloose Motor coils often have a very low resistance <20 ohm.
If you get an open circuit, something is wrong.

Do you have a multimeter for resistance measurement?

In other words, if you salvage a motor from something, mark it with its nominal voltage. Throw out unknown motors. You'd certainly run them at the wrong voltage. Results are anywhere from degraded lifetime to downright dangerous.

There's your answer.

12V

(In reality the 2V below the smokey, fire, breaky, explody point)

@linuxxx thanks for the mention 🙂

12V shouldn't hurt. If it gets hot, tone it down. But it it stays cool, no worries. You could even go higher. Also FUCK OSK KEYBOARDS!!! 😡

@PonySlaystation Yes I do

It's dead... but also tested a similiar motor and it works :D to bad the shaft it's only 3mm

Does the shaft turn smoothly if you try to rotate it with hand?

@N0-Flux-Given Nope, it's jumpy...
But ya, I'm considering it dead...

I feel it's dead. But yeah, if you know it's rate/min, you can attach it to another motor of the same rate and see what the output voltage is(if any). Maybe check it's resistance to make sure if it even works...
