the change or derivative of current in an inductor is equal to the voltage. The change in current is fast as the motor spins creating very high voltage, infinity from a mathmatical standpoint but only for

an infinitely small amount of time. The reading is all voltage but no power or the ability to do work.

"the change or derivative of current in an inductor is equal to the voltage."

The more voltage, the quicker the current rises. No doubt about that.

Thanks for another comment to my video (even though it is obsolete). :)

what is this motor suposed to do?

[kmarinas86]

Nothing. But not to worry...

This motor no longer exists. See my latest videos on my newer motors by clicking my name.

Your multimeter simply has scrambled brains and can't measure what you are asking it to measure. There is no way you are measuring 1000 volts, you would get shocked, burnt, and possibly severely injured.

It would also help if you tell your audience in a clear and definitive fashion what you are measuring when you make your clips.

It claims to measure over 1000 volts in RMS. I bet most of the time it is not even close to that. If there is a spike in that range, it is probably for 0.01% of the rotation. If this machine is really reading voltages this high, then they must be much higher for much shorter periods of time with very little charge associated with it. That's probably why I'm not dead yet :)

U r weird

you read those high voltages because the batteries are like capacitors, they are almost like a short to AC. When you have low power high voltage, your current is extremely low. You can read it in your circuit because its being passed through the batteries like if nothing was there.

those little voltage spikes you made damaged your meter.. good thing its only money.

[Drevtoobe]

What's the exact brand, name, and model number of your multimeter? I am curious enough to read the user manual.

You are right that there is the possibility of ultra-thin spikes approaching 1000 volts. In fact, the theory states that the sky is the limit, and under ideal conditions, it is probably possible to produce spikes that are tens of thousands of volts. (On paper the voltage limit is infinity)

However, the most likely scenario is that the RMS measurement only works under certain conditions, and outside of those condition the multimeter "goes crazy" and the algorithm inside the meter can't deal...
