Eric, thanks for you answer, im gonna try myself!! really there is a no clear what make it works????? i found this verrrry interesting!!! sorry the bad english. Greetings from Argentina. Raul

You noticed that I had to answer in 2 parts, becasue of the 500 words limit.

Good luck with the experiment but be careful, things can get hot.

Part 2:

I mounted the bearings on a plastic board to avoid holding it by hand. Check that the shaft can rotate. Then I connected both bearings outside rings to a car battery. I needed to start the shaft but then it rotates fast. The bearing are getting very warm so I didn't want to keep them too long under current.

I don't know if it is dangerous (blowing up the car battery?) so I don't want to advice to make this. I measured 119 A and that is much.

Very interesting, please explain how works, thank you!!!!!

part 1:

I can explain how it did it, but I cannot explain what it is that makes it run. Some say it's magnetic forces, others that the balls are expanding and thereby flipping.

I used 2 bearing and removed the grease from them. Then I mounted both bearings on a shaft. You should measure with an ohm-meter that the 2 outsides of the bearing make contact with each other.

Look ma, no magnets!

[VanDeGraaff]

Oh yes it can, many car owners and mechanics are blind from battery explosions. Car batteries are mean bastards.

Be mindful of what you say, if someone got blind from blowing up a battery because of what you wrote here, you would be responsible!

It is saddly just ohmic heat, you can find the explanation on Mike's electric stuff..

[GraffixWB]

LOL.. I LOVE this!!! I'm an EE student. I tell all my peers all the time that we don;t know shit. here is the proof

Great video.. 5 stars

The battery is 70 amp, the 119 amp is it generated from this bearing motor? Thank you in advance

It's a precaution

It isnt going to happen straight off the bat, the seoncd you short it

It's rare but possible, and ive heard it happen before.

[LeoDJ1992]

I've shorted a lot of car batteries and that has NEVER EVER happened.

[Driv3th3hiv3]

When a lead acid battery is discharged it releases explosive gases

When a lead acid battery is shorted it can produce around 500-900 Amps and this heats the internals of the battery causing the rapid production of said gasses to explode, spraying hot acid everywhere

can your motor take a lode.?

[leonardnemoi]

The shaft of the ball-bearing-motor appears to be rotating. The two metal cylinders seem to be rotating as well.

Where are there "ball-bearings" involved?

[Davioware]

does the thing rotate because the eddy currents heat up the bearings in a circular fashion, and the high precision of the bearing allows for this (i would imagine) very negligible rotating pattern of expansion to create rotary pressure on the axle like in a Wankel engine, thus turning it?

[gomemdesoto]

The battery will vent explosive hydrogen gas while under these almost short circuit conditions.
