A strange electric motor
Вставка

- Here there are no windings, magnetic fields, magnets, brushes,
but only two bearings connected by a conductor axis.
In this motor the current flows through the first bearing, the axis
conductor and then the second bearing. The electrical contacts
are applied to the outer rings of the bearings.
1. the engine must be started.
2. the motor rotates in either direction.
3. the engine is running both direct current and alternating current.
The power is approximately 3-5 Volts with very strong curre.
(this is basically a short circuit)
"Ball bearing Motor" the current passes through inner race of one side ball bearing , then to the shaft , outer race of other ball bearing , then to inner race , causes a temporally expansion of each ball , deforms it to elliptical and adds pressure between inner & outer race then cause a moment of rotation , for that reason , it needs a prime movement to sustain rotation , by the way it doesn't matter whether the current is DC or AC , it just used to heat up the balls.
Electromagnetism is where I felt in love with physics and now in Science in general. this is art to me!
Me as well!
Shit, home slice. Electrostatics will get you to fall in love with magic. Electromagnetism is so basic in comparison
@@bugabookatzenjammer661YESSIR, I am assuming due to your reference that you're at least partly referring to Dr. Chuck Buhler, the NASA electrostatic's chief expert responsible for the upstart Exodus Propulsion Technologies? He literally figured out a propellantless engine that already slightly exceeds a 1G acceleration curve, not much within an atmosphere, but throw that system in space, with adequate power and well, just do the math, we could make it to Mars in less than a WEEK. Alpha Centauri in less than 8 years. All thanks to... ELECTROSTATICS!
I should add a few points: First, I like it. It's a great demonstration of induction motors. Second, if you replaced the heavy copper mountings on either side of the rotor with two coils and passed a current through them instead, you would have something very similar to a regular 2-pole induction motor. No need to make the current go through the rotor spindle. Adding some shorted coils next to the main coils would produce the "shaded pole" effect and the motor would self start. I'll try it and post the video. Or you could do that yourself....
This motor is based on magnetostriction. The ball bearings undergo a shape change as the electric current is passed through them. Since the ball bearings are in point contact with both inner and outer race of the ball bearing itself. The motor, once started by hand will allow this alternating shape-change to force the rotor to rotate. Eventually the steel balls hard and polished surfaces will degrade due electro-erosion and the point contacts will be reduced thereby resulting in slowing down and eventually coming to a stop. It’s a laboratory curiosity and has no use in the real world.
I like it, I really like it. Since you're not using any magnet's you're no longer bound to their properties at high speeds. Now I want one, too
The spinning disc itself is a strong magnet
It is not the balls heating up and changing into an elliptical shape that causes rotation,as the balls being that shape would exert the same force in either direction that would cancel out any unidirectional force that caused rotation. The rotation is caused by the two magnetic fields produced around the inner and outer bearing races,and the opposite field being created in the balls. Depending on which way you spin it,determonds which half of the magnetic field in the ball is closest to the opposite field that is created in the rings of the bearing's. Grab yourself a compass,and place it near the bearings when the device is running.
+TinManPower Look into Faraday's Disc. I think you'll find it, and this video, very interesting.
+TinManPower from your explanation, do you think the size of the bearing would effect the rotational speed or torque. I mean would a larger bearing have more speed and torque???

Ehmm indeed, replacing carbon brushes motor to bearing carbon motor for decrease fraction.

Brilliant video. Never thought that this was possible
Its works on Induction motor Principle
@@shivaprabhu3204 This is not an induction motor.
The bearings heat up. Because the connection is better on the bottom because of the weight of the rotor the heating/expansion is uneven which gives the rotation.
+Richard Harris Nope!

Roobert33
The rotation is created by means of thermal expansion of the bearings as I said - more or less.
+Richard Harris more or less as well as I have said many times ;)
Sorry yes this is a well known mechanical effect.
Seems to be an induction motor. The current running through the bearings will most likely ruin them due to arcing between the race and balls.
what if you used journey bearings?
@@matthijsjanse3275 journal*
There are magnetic fields. This can not be argued for there is a current of moving electric charge. However, you could argue (wrongly I believe) that the motion of this motor is not due to electromagnetism but to thermal expansion of the ball bearings in the race.
how long before the bearings are completely destroyed?
They last only a few minutes.
@@ElectricExperimentsRobert33 hahahaha I wonder how much heat that have generated.
@@ElectricExperimentsRobert33 Did you try to spray the bearings with cleaner and lubricant every once in a while? I have a Cylinder spray (pink color) by Nortek and is called Clean and Lube - I use it all times for my electric and electronic works - it is great for all electric works similar to this.
@@fifaham not sure how well thus would work. In essence the motor works by heating up the bearings at the point of contact by a few microns. It’s not a lot in the grand scheme of things but with the tolerances seen on bearings it’s a lot. Mix any kind of lubricant into it and it could possibly cool the bearings to a point that their efficiency is dramatically reduced or even cause it to stop working.
@@adampolson6938 Thank you - I see that cooling the bearings will oppose the purpose of movement.
Its part of the infamous homopolar generator, however, you are only using the "motor" part of the principle. Tesla's version had both the generator and the motor functioning as one unit. Long story short, you would spin one disk with the magnetic field oriented in one direction, this would spin the electrons out from the center toward the periphery, the electrons were conducted via a conducting belt to the other disk, spinning the same direction, but the magnetic field was oriented in the opposite direction, causing the electrons to flow from the periphery toward the center, thus "motoring" the second disk, there you have a self exciting or self running dynamo electric generator.
This is the best motor/rotor I have ever seen!!
Ball bearing motor works due to heat in the ball bearings ! It is just a simple STerling heat engine this way, but the effiiciency is low...
Stefan Marinov has presented this years agó !
Regards, Stefan.
Interesting! I think this design has a very low torque output. There will be a magnetic field, but it is very weak since there is no coil, so you need to start it spinning, and a finger can slow it down.
Paul Sutter Yes ;)
+pds tech add gears for torque
the rotation is caused by the bearings , the arc makes them grow , this distortion is complementary to the rotation
The distortion is tangential to the rotation. Complimentary described acute angles that add up to 90° which doesn't make sense.
Rýán Túçk oh bullshit wise ass, you are so full of crap, i got this statment from a book i own that was written by electrcal and mechanical engineers on exotic batteries and motors and how the fuck do you get off telling me the distortion is tangential to rotation? also com·ple·men·ta·ry

Steve Blount yep loving Jesus doesn't make you a push over or a saint , whats your excuse steve. i do get way to defensive id be a fool to argue that, i got mad because he does not no what he is talking about and yet here he is telling me how things are. in the mean time thanks for your support and joining him in are argument you are both cut from the same cloth i presume and maybe thats why you hate me so much, have a nice day atheist shit bags
It's a single phase a.c. induction motor. The current in the rotor shaft and in the rotor itself is unimportant. The current on each side, going up from the connector to the bearing and down from the other bearing to the other connector creates a horizontal magnetic field tangential to the rotor. Eddy currents induced in the rotor cause the rotation. It will run either way.
Thank you for a good explanation.
Incorrect. This motor can also run off of DC. This motor works off of the thermal expansion of the balls in the bearing. www.physics.princeton.edu/~mcdonald/examples/motor.pdf
Try making it work with a flame, like a welding torch, to heat the bearings. It won't.
OK Then where are the coils?
I'm sorry? did you even read the article you linked?
it works based on a minute magnetic force from two contacting conductors.
This is an Induction motor Robert sir, the high voltage choke is inducing eddy current in the metal rotor 🙂.
This is very interesting. I get the feeling that the current going through the bearings may be where the rotation force is created, the ball bearings being charged, and reacting to the bearing races? With that in mind., I would like to try this without the center flywheel to see if it still rotates the shaft. All in all, it is pretty amazing.
Without flywheel it takes little couple ..
You came the closest to what I think is happening. Heat is the effect, magnetism is the cause. I was watching the mayan engine. It showed a magnet cut on a 45* angle on the N and S ends. Inbetween two parallel South sided facing magnets. The 45* angle magnet slid off rapidly to the side. If the 45* angle magnet was the ballbearing and the race and outer ring were the S facing magnets then, this is why the motor rotates. Not heat which would slow the motor down until it seizes. Car engines have starters, we used to crank cars over by hand.
In my opinion, the flywheel is axially magnetized. Current can be either direct or alternating. When current flows through the two bearings supporting the shaft, the balls become conductive rods in the magnetic field and the balls are pushed in the same direction, so the shaft rotates. The direction of shaft rotation, with AC depends on the direction of the axial magnetic field of the flywheel, with DC depends on the direction of the current and the direction of the axial magnetic field of the flywheel.
Excellent video. Amazing how long that flywheel keeps the shaft spinning when power is disconnected.
electronicsNmore Many minutes.
Flywheels are very useful. I found a few at the dump, so I will be experimenting with different sizes on my 40W homemade crank generator with supercapacitor bank.
hi did u r bearing motor worked
Srx.tinta
Very interesting. Does this motor produce a good amount of torque?
Enough to make it run for many minutes.
you video is beautiful, love the simple and clean idea you have .
because high current is technically simply passing through a conductor, there must be a magnetic field present. You pass current through a straight wire and the field will rotate at 90 degrees of course. the question is what makes the rotor spin lol. what is the created magnetic field in the shaft interacting with.. I have to assume lorentz force is working here and somehow either each bearing and each end of the shaft, or something else is creating a field as well.
Very nice build.
Bill
Pirate Labs Thanks Bill :)
Good and beautiful, but it would be preferable if you wrote some explanation for us, measuring the bearing, for example, how many amperes did it consume to rotate, and what were you doing with the switch, were you just disconnecting the electricity? And then you get it? . The video is very important, thanks
That's a beautiful motor. It appears that eddy currents are more useful than we think. Isn't that how the old electric wattmeter or energy meter (measuring kWh) works - a rotating disc of aluminium driven by a current-carrying coil? The drawback in this case is that the whole of the motor is electrified - hence the gloves, I would imagine. The amperage is also very high, and if the motor stalled for any reason then excessive heat would be generated. I would think that is the reason the low a.c. value of 6V is needed. It would be nice to measure the efficiency of the motor (i.e. mechanical power versus the input electrical power). It might be very low, frictional losses notwithstanding.
Electro this motor uses thermal expansion of the balls in the baring to run, it is extremely inefficient, but cool.
Mike oliver no, it's the magnetic fields produced that drive the motor. I don't fully understand it myself, but it's certainly not the balls. That would generate an equal force in both directions, thus producing no power.
why not insulate the bearing from the shaft and induce the same current to the shaft itself using a contact the field would be the same and the bearings would not overheat due to the current passing thru the bearing assembly. but still it will have the same pos or neg potential. and it may eliminate the heat problem.
I wanna see what happens when a bearing seizes with that mass turning at that RPM.
That would be fun. ;-)
lots of glowing metal, smoke, and sparks :D
I don't think it has anything to do with heat. It is either the torque on the electrostatic dipoles of the balls in the field between the two charged outer rings (when the balls spin their dipole moment is slightly offset from the radial direction due to the charges requiring some finite amount of time to rearrange) or it is because of the magnetic forces between the currents through the balls and that through the outer ring. All of the theories can be proven easily by changing some parameters and doing some measurements on the system.
I love a kinetic flywheel! ive researched them a lot, Williams racing has a 16 minute that tells why and how they are so monumental! never seen a "ball bearing motor" before, also interesting! I will have something of this nature aboard my EV's later than sooner, but im making progress! great clip, look forward to more, thanks for posting!
Have you tried this with roller bearings? The greater surface area could make the bearings last longer(or get hotter), if they're as thick as the ball bearings. Unless the many angles of the ball is needed to create this magnetic effect, The one angle of the roller bearing should be enough. It's not a heat engine. It's magnetic energy produced by the high amps. If there's current, there's magnetic fields. 230v to 6v, 20a/6v=0.3r, 0.3r/230v=0.0013a The flywheel works just like a flywheel, torque is stored in it. Hear the bearings squeal while torquing up the flywheel?
Sounds like the bearings need some graphite lubrication on them.
+Ortorea Screenname u have a fascinating face
The main advantage of graphite is it can be a dry lubrication and does not drag as much on the bearings, having tried silicon grease and seen heat dry it out it can set like glue. WD40 for example increases in viscosity as it dries out and becomes like glue and can cause a lot of drag as it dries out. But Graphite behaves in a different way as it can be both wet or dry lubrication. Provided the graphite is not suspended in a silicone based liquid that is. I would suggest experimenting with various types of lubrication as I have tried many on my large house fan as it was prone to seize up or squeal at me due to heat from the motor.
Put an airline on each bearing this will keep the bearings cool, and use a graphite, copper Grease.
Rewound mot would be ideal for this!
What's rewound mot?
Good it rotates without any magnetic/electric field.what is the torque and speed it can generate?
Il créait son champ magnétique . . .
The shaft is being driven by the bearing balls heating up at their small contact point and expanding. When the shaft is rotating this causes a push in the direction of the rotation, speeding up the shaft. It's very inefficient and damages the bearings, but damn it is neat.
I might be wrong, but it is fair to assume that all baring balls are heated equally and at a same time, without any phase delay. So, if all the ball bearings are heated simultaneously, and there is no phase delay, this motor can not rotate because heating of the bearing balls.
I would rather say that it is simply a version of Faraday's Homopolar motor.
The phase delay is caused by the contact point on each ball heating up & expanding locally more than the rest of the ball combined with the rotation of the bearing. The hotspot is rotated away from perpendicular with the shaft while still expanding causing the torque.
This is why the shaft usually needs to be rotating when current is applied for this to work. Sometimes due to part tolerances you can get the shaft to spinup from a stop, but only rarely.
Robert Szasz
Quote: "... The hotspot is rotated away from perpendicular with the shaft while still expanding causing the torque"
Just want to check I understand what you are saying. In essence bearing balls are expanding, while rotating, and that causes torque? Is that right.
The critical bit is that the balls aren't expanding all over at the same rate. The point in contact with the shaft expands more, as it rotates away and pushes against the shaft a cooler spot contacts the shaft, heats up, is replaces by a cooler spot, etc...
This certainly produces some thrust. How much of the total would require a large amount of work.
It would be interesting to run a ball bearing motor made of superconducting materials when below it's critical temp, as you can't deferentially heat an active superconductor.
Robert Szasz
Thanks, that sounds very interesting. I was more inclined to believe that it was connected to Homopolar motor effect. But this sounds completely reasonable. I just wander if it would be possible to replace balls with some other conductive material like carbon. These bearings are not really suffering under any heavy mechanical load.
basically, moving charges produces magnetic field!!!
as mentioned the contact patch on the balls expands as it heats up from current. No preload needed just the weight of the assembly on the balls is sufficient.
This is Stefan Marinov's ball bearing engine...
The bearings are either having an electro-magnetic charge as a result of the copper around them with the electric charge or the bearings themselve are homemade with the magnetic spheres. You aren't getting one over that easy. Clever set up though.

It is a vibro-engine. Vibration is coming from two normal alternative currents magnetic fields interaction.
I really dig this machine a lot. I've watched this presentation many times. I see great potential in using the stored energy within the system, which can be syphoned off that flywheel (which could be made much heavier... instead of 5 pounds, try 50 pounds) to make lots of electricity, some of which will power the device and keep it running... dare I say it, endlessly.
Try creating a vertical axis version, which will reduce the stress/wear on the ball bearings... and add an airing to the base of the shaft. An "airing" is a pair of magnets facing off to create an air cushion, i.e. no friction from metal to metal contact.
I will also add that there is no such thing as a homopolar motor, or indeed a homopolar anything. Magnetic field lines are always closed loops.
Very nice, an interesting conversion from electrical to mechanical energy!
its an off on swith and the flywheel keeps it running for a long time
dont focus to the metal disk. its about ball bearing.
Si lo tocas cuando esta encendido, da calmbre?
This is nothing more than a Thermokinetic Motor. They were invented many years ago. They are not really Electric or Electromagentic motors at all. The AC or DC currrent is a convenient way to heat up the bearings to produce torque.
+Jeffrey314159 Yes ;)
Does it mean, that such a motor with smaller bearings should rotate faster?
More or less..
+Electric Experiments Roobert33 are they more powerful than dc or ac motors?
+SMOKER I think they are too unreliable...
Cool. Have you measured the current? RPM? You left the power on for only a few seconds at a time. If powered for a while longer, will it continue to accelerate or does it stabilize at about the RPM shown in the video?
Philippe Jacquot Yes, makes sense.
Imaging this on a bike or 1 man vehicle. Pump up the RPMs in one direction, then use a lever to change the flywheels direction quick (like putting your car in gear) and ZOOM! Then you can charge it up every time you stop, or have some low amperage unit keeping it spinning as your go. I think it's so practical and could easily be implemented in a gas combustion system as to not disturb the powers that be.
+Paul Trace You can mix up the semantics all you want, but what we have here in this video demonstration takes place on the macroscopic level
+Jeffrey314159 whatever that meant
@@anonymousknight2881 This a 'thermokinetic motors', nothing more.

yes, the heat creates the ball expansion in the bearings
The current flow is equal to the rotation, and the rings a constant to any current had you no other choice to read the current flow using a stroboscope, I wonder which was created first the stroboscope or the voltmeter, for reasons the wheel was first? What is most intriguing is the round rings on the rotor, a natural and logical indication to rotation, it's mysterious, and a heavenly wonder!

To be clear the contact at the bearing is still engaged to the input current from the source you just add the field to the shaft too while the insulator on the bearing ID prevents the arcing.
The flywheel is likely made of "soft iron" (easily magnetized and demagnetized). The alternating current magnetizes the iron, which then interacts with the field from the circuit. This also applies to your other video with the washing machine motor.
Alternating current does not magnetize... Direct current magnetizes...
Landotter1 Actually alternating current does magnetize. This is how the principle of induction works. The difference between an AC magnetic field and a DC magnetic field is that the AC magnetic field's poles are oscillating at the frequency of the signal, whereas the DC magnetic field's poles do not oscillate at all.
Landotter1
Explain how a an AC solenoid works then?
AC can magnetize.
your explanation doesnt explain why this wotor works with DC currents.
AC DEMAGNRTIZES not magnetizes. DC magnetizes iron
Best 😅😊😊❤❤ Motor ever😅😅😅🎉🎉🎉🎉🎉🎉🎉🎉
I don't know how it's works
It's kind of hard to explain, if you have a basic understanding of electrical and thermal physics then you should be able to understand it. Look up a study paper or an article explaining how it works if you want to, they will probably go into more detail.
It's a homopolar motor
The current flows through the shaft & flywheel while the magnetic field surrounds and spins around both, but centrifugal force of rotation will also tend to throw off electrons, possibly interacting with the field, kinda' like the Searl disk. Why not spin it vertically with some outboard magnets and see if it takes off!
Sigh. If only people could *see* electric and magnetic fields these things would be mundane and obvious. No magic, just physics.
Certainly that is physical.
if only we could get half the fat kids off the couch to even try this mundane and obvious physics, life would be a thousand times better.
besides, I don't think baking brownies is that much more magical, still doesn't stop me from making them. ^^
interesting but the rings on the inside are magnets right and the outer rings are metal so when you run a current across them an apposing magnetic flux is created and the Motor spins.. simple but realy cool motor. you can also generate power by spinning the rotor.
The Motorless Motor!
Anything that generates kinetic activity can be called a motor
What about it, Kyle?
Not exactly, Jeff. Our muscles do that but they're not motors. The wind does that but it's not a motor. Gravity, a lot of things.
Nice homopolar motor. Lorentz Force in action. Best example I’ve seen yet. All the others I have seen create to much heat from tiny arcing to spin fast. Thanks.
I doubt those bearing will hold very long with them running dry like that.
Jacobus Hough In fact, they only last a few minutes :)
Electric Experiments Roobert33 so why don't you apply some drops of oil to them?
RadimentriX Right question; the oil is an insulator and impedes the flow of current, therefore it rotates very little.
Electric Experiments Roobert33
hmm, too bad :< doesn't something like "conductive oil" or another conductive lubricant (with little resistance) exist yet?
RadimentriX Maybe the fat graphite is a conductor can be good, but I have not tried it
is it a form of tesla iron lag motor, its very basic and similar to this design, iron slightly magnetizes and holds a field till another pulse comes along and causes a force of rotation.
With the wheel turning it creates its own electric field so keeps spinning .
Put some magnets on the flywheel moving past coils for another way, also if you attach an electric motor to the generator shaft to create the intermittent start up power supply with capacitors. Just a thought
Bearing torture!
Dead short on the power supply.
What about them?
Electric current heats a bearing and changed it shape which makes this drive running. The problem is that it can not run for long and the question is about efficiency.

ball bearing motor, swells the ball bearings to push the rotor through high current.
+Gareth Compton Nope!
Correct me if I am wrong, high current (little to no resistance) draws a whole lot of current to the motor, especially if it is metal. Also the efficiency would matter as well because that determines how much heat (aka swelling) occurs to the bearings. There is a UA-cam video explaining this principle. If you start it without it spinning, it will still swell but damage the bearing whereas you have to spin It for it to swell and push it to rotate.
+RyuDarragh I'm no expert but I agree. for the thermal explanation to work the bearing would need to be preloaded. the rollers are so small even if the localized heat was absurdly higher than then rest of the bearing but under the melting point and the rest of the ball fell back to room temperature instantaneously as it was rolling you'd still be measuring the expansion in microns. these motors are still running as the bearings are failing. I could imagine a motor that did run on heat like this but it would need to be larger with either tapered roller bearings and an anti backlash device or bearings that are interference fit.
your explanation made my balls swell too. NO HOMOpolar motor

Very beautiful video!
Bello! Il motore a corto circuito
Notice he does not disconnect the wires while it is running. Which means there is current still running through even though the switch is supposedly turned off.
Nice Set Up!
This motor could win the record of the world's most inefficient electric motor...perhaps.
There is also one that works like a cumbustion engine but its electric. Pistons are moving in a coil and a mechanical contactor switches the current in the coil so the piston moves in the coil, once it reaches its max position the current is switched of and the piston moves back because its connected to the shaft. And so on...
Incidently, the first mechanical motor to employ Electric Force was not invented by Faraday, for his used an electromagnetic field to induce motion. In Benjamin Franklin's day he had made a rotory motor that was propelled by electrostatic fields. He even invented a practical application: a device that warned of an impending lightening strike on your house!
Yes a bit strange. Nice presentation once again sir.
Principal is the same with 90 degree gyro effect. When we push a rotating mass like rotating electric motor, push direction gives effect in 90 degree angle to axial.
In this example ‘short circuit’ gives a way out by that gap or 90 degree gyro effect; but changing the electron axial direction itself. Actually good QM experiment…
Drum mass doesn’t change the power a same mass but wider and thinner drum would give more power because of momentum distance.
It is a funny experiment and giving a clue about why 90 degree. It is actually two times 45 degree in duality…
You see why in this video; of course the purpose of the video is not this experiment but you can get the clue.
The Double-Slit Experiment is SOLVED
Not really sure about the reason why this motor works but I do know that AC going through bearings causes fluting. Several companies make a lot of money selling products that reduce / eliminate current passing through bearings. This motor is using the bearings as a conductor so bearing life will be relatively short.
+David Howard Not sure? Could you give me at least one vague reason?
i remember my grandfather had a compressor and you had to spin the wheel then hit the switch to start it up then you had to throw the belt on it. sounds funny now looking back but it was the best big compressor i have seen to this day even! good job i want build something a bit more sophisticated i think.
i think because of the bearing it rotates so smoothly and it lessen the force that can interact to stop the iron flywhell to rotate. its kinda first law of motion.it stay in motion unless their is an unbalance force acting on, causing it to stop.
Hi. I noticed in this vid you kept switching the device on-and-off......on-and-off.....on-and-off.
What would happen to it if you just kept the power on?
Would it spin up so fast that it would fly apart or melt the bearings or something like that?
Nice little demo though. :-)
Thanxx for showing,
-BoomBoxDeluxe.
The bearings are screaming !!! , you may use another type of bearing that has plastic from both sides ... there is grease inside it , you can put two of them each side the rotor if you want .
Regards
It works by thermal expansion of the lower bearing balls when the high current goes thru them. I am surprised nobody in the comments is saying this
if this was the case then the passing current through the device when the wheel is stationary within fractions of a second would make the balls stick in their place and it wouldn't be possible to set it in motion afterwards. And this can be clearly done.

@@audiodood it requires analysis and calculations and I am not sure i can do that easily. It also requires experimentation and measurements. The currents involved are very high.
Mind Blowing Torque
This is a monopolar motor. It rotates as the Earth does.
Bah - hit enter early - did you happen to record what it's top rpm was? Did you play with frequency at all of the voltage to see what effect it may have? I want to build one now. :)
I'm going to guess the center rod is generating a strong magnetic field at right angles to the direction of current. Due to the hit and miss action of the bearings transferring the power the balls get dragged along by the fluctuating magnetic field. Just a guess though.
It's called a ball bearing motor , discovered in the late 80's, the high amount of current causes each ball to expand making an eleptical shape produsing a tangent force then rotation , it's not practical due to low torque and a prematurly wear out .
That is just plain cool! Great job!!
is there a reason why you dont let it ,ax out its rpm ? its frustrating to watch
it's called kinetic , Kinetic energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity
in reverse you can output some electric in which electric car use for charging their battery
Tom Hoehler I have not tried it with the bushings, but I think it does not work.
Very interesting! Of course the claim that no magnetic fields are involved is bunk. All electric current always produces magnetic fields. Given that ball bearings are hardened steel, I suspect this is a novel form of an hysteresis motor or of a reluctance motor.
Además del motor fascinante, me gustaria felicitarle por la calidad de los soportes de madera y las conexiones eléctricas. Saludos del chico electricista.In addition to the fascinating motor, I should like to complement you on the quality of the wooden mountings and electrical connections.Greetings from the boy electrician.
Do the bearings have an even or odd number of rollers? If an even number, would it still work if the number of rollers were odd? If an odd number would it still work with an even number? Would this unit still function the same if dielectric sparkplug grease was applied to the bearings or if it was submerged in mineral oil?
+Paul Trace It should work under all these circumstances. Maybe not with a thick grease.
