Thanks to TH-cam users Mark Horstmeier and ramosel I now doubt my own explanation in the video. Please read
www.physics.princeton.edu/~mcd... for a better operational theory.
Ball Bearing Motor
The parts:
(None of the dimensions is critical. Material doesn't matter as long as it conducts electricity.)
3 M6 stainless Nuts, 1 M6 stainless Bolt (50mm long) , 2 Ball Bearings (OD: 20mm, ID: 6mm, Width:6mm, seals removed, grease removed with brake cleaner), 2 flexible isolated wires (Diameter 1.5mm, Length 20cm) Wires are soft soldered to outer races of the bearings.
The power supply: Old 12V Battery charger with conventional transformer.
Batteries must not be used (current way too high!!) Modern (eg. computer) power supplies are unlikely to work, as they switch off totally when short circuits are made.
Kids! Don't do this at home! Danger of burns, fire and electric shock.
Be sure you have a residual-current circuit breaker (RCCB) installed. Never use mains electricity directly.
Here's an explanation of the thermal theory (which I doubt after reading Kirk T. McDonald's paper):

Electricity scares me. That is why I mostly play with fire.
Va gina de ick
I have a turtle head poking out of my shitter right now.
I haven't seen one of these in years. In the mid. 80's we were playing with these things, we used a ballast resistor to limit the current to something reasonable and truck batteries for the source.
There was a massive write up and argument about how they worked in New Scientist at the time, the articles went on for months. I didn't believe it from the write-ups so I got the lab to build some test models.
The larger the bearings the more likely they are to self-start. You can also apply power to the inner bearing and have a tube attached to the outer bearing and spin the tube
very intersting. can you send a link or information about these publications? I think thre thermal explnation is problematic.
No I can't. You claim to be a professor you should be able to do a literature search on New Scientist, or even google "Ball Bearing Motor" which takes you to "en.wikipedia.org/wiki/Ball_bearing_motor" Maybe it was before the mid 80's it was a long time ago, and they are saying late 70's. I'm willing to go along with that. Really for a professor asking someone to even do basic things like look on Wikipedia is a bit much.
@@salerio61 Thank you for the rapid answer! I was referring to your sentence: "The larger the bearings the more likely they are to self-start". I could not find this result in the literature. I have another suggestion for the rotation mechanism, electrical (not electromagnetic), and hoped to see if you also suggested it in the past. Thank you!
It was empirical observation. Get different sized bearings and try it
I just got them today, hope to do the experiments tomorow.
This is simply a single-phase induction motor with no capacitor start facility, hence the flick start. It is electromagnetic.
No, sorry, guess again.
electricety -> magnetism
+way qsx electricity that moves = magnetism (also magnets that move create electricity)
Do you even listen to yourself? Dude it IS magnetism LOL. You guess again
You can talk from your ass?
Very Cool! I dont think the explanation on how it works is correct, seems to me that it is set up similarly to a rail gun; but I could be wrong, I'll have to think about it some more.
nice seeing you here
Hey Cody! Big fan of your channel. Do you know why this works, and if so, you should do a video on it. Maybe even make a larger scale one if possible.
yes I do agree, this might clarify: www.physics.princeton.edu/~mcdonald/examples/motor.pdf
hey cody, get those thumbs up. seriously man. it's time.
If the claim that thermal expansion of the bearings is true, then one might see better efficiency scaling it down. The thermal expansion great enough to push the racers of a larger bearing would require significant heating/cooling gradient rates.
1. its a homopolar motor and any homorpolor construction gets hot very quick and thats why these types of motor are not in use.
2. Its a battery charger not loader and using the charger to power things is not advised because of the amount of current that it can deliver and the damage you can do to the internal circuits.
this is a clear example of electro magnetism..
The noise at the end of all those videos playing simultaneously was amazing. I could listen to that all day.
its oddly relaxing
im amazed at the fact that someone would actually think about creating a dead short through 2 ballbearings
New or old, practical or not, however it works, you made people think and that's good.
Nice video, thanks.
while I congratulate you on your home experiment, the reason this wouldn't work in long term applications like cars or tools is that the bearings would fail rather quickly due to electrolysis and heat. set it up in a vise/test bench, hook it up to a load (say a fan, etc) and let it run for 30 minutes or an hour. see how hot it gets. then run it till failure see how sloppy the bearings get. that's why graphite is used as a self lubricating electrode in today's wound multipolar motors. and the bearings are isolated from electric current.
use swiss ceramics
fknra: Just a question to your comment and believe me I'm not being a smart ass or being rude I just wanted to ask. What if the bearings had the seals in them and were packed with grease like they are for other uses, would that not prevent the heat and wear? Or is this different with adding electric current?
Marty Mcfly the heat would still be a problem. sealed or not. the creation of heat is a problem of induction. the more amperage/load, the more heat (which is also an issue with normal electric motors) but running any type of electrical load combined with the physical load and eventually (rather quickly) arcing is going to pit the bearing surface and you'll suffer failure.
Wun Wun do Swiss ceramics transmit electrical current? (not sure which ceramics you're referring to)
Thank you for an interesting display on the interaction of electricity and the ensuing magnetic fields created in the metal. Classic.
WOOW ! What an AMAZING selfrunning SHORT CIRCUIT !
yeah it seems inefficient
+xxuncexx
It IS inefficient.
Yes ... not simply inefficient...it's a joke. it can't work in any ways. A total waste of time.
Try other devices HHO, MEG, GEET, BEDINI etc.... surely better than this.
+mptrax
actually, the physics behind it are explained in the video, and I have tried it myself. It works...
It's an amazing device for welding ! Just that.
the heating part is not something to brag about, if you are trying to make a motor for propulsion then crating heat is the same as trowing energy out the window. that is one of the problems with conbustion engines, about 75% of the energy in the petrol will turn into heat, and not into motion. SO basically you have dragged one of the major downsides of combustion engines over to eletrical engines, making it a lot less eficcient. cool discovery tho.
not much of a discovery....the same effect happens every time you turn on an incandescent lightbulb.....
exactly, and even then, the heating part is wasting energy, you want ligth not heat, it is not a bonus. that is why LED ligths are more efficient
since youre the wise god i figured it would be a good idea to check out your channel before bashing you, just in case you uploaded some fundamental shit. instead i come to find you have alex jones talking about michelle obama being a tranny in your liked videos, so im going to go on a limb here and guess you also believe the earth is flat and everyone should drive teslas.
there is a magnetic field being created. the ball bearings are acting as an armature and the outside race is the stator. this proven by spinning the bolt after the field is energized
Three cheers to Latheman! For those commenting on the lack of use of a motor that bogs down when put under torque, let's look at the positive "what is possible" aspect of this video. Problems are simply opportunities in the making. Latherman got us started, let's now solve the torque problem. Great video Latherman!
I had the same idea about a week ago. Nice to see that it actually works.
Excuse me but this is not a heat engine. It is an electro-magnetic engine closely related to rail guns. The current passing through the bearings create a magnetic field and the force applied is 90*deg off the flow of current (right hand rule).When the bearings are not turning this force is equal on both sides, but when you spin the motor the force is unbalanced, so it spins faster. Basically, it works like a rail gun ejecting the projectile but keeping the bearing inside a circular race.
AHHHHH. Nice one m8. You just revived my faith that not everyone is a complete asshat.
Some of the uneducated dross and even willful ignorance in evidence in these comments are pretty awful to witness, albeit perfectly "par for the course".
If you say so, here i am thinking that i'm an electrical engineer.
Obviously not a very good electrical engineer. Steel is not a good enough conductor to create a magnetic field big enough to do the amount of work shown. Please refer to the documents Latheman posted in the description. Also look up other examples of this motor.
Nicolas Marez, thanks for the heads up. I hadn't read the description (facepalm). I find the Wikipedia page lacking. While the edu paper is technically true, he doesn't talk about slop in the bearing and the ball cage is also conductive. As usual, engineers look for the most important cause and forget all the other smaller explanations.
Felep Channel Which is worse? Being late to the party ot being a lame ass troll with no repartee?
That thing must draw a lot of amperage. By the way, it's operating via electromagnetism, and not ver efficiently.
I can't imagine just how hot that conductor gets.
he said electromagnetism, it is different to just magnetism. electromagnetism is basically creating magnetic fields and sustaining them using electricity (the moment electricity goes your electromagnet goes as well) whereas just magnetism can occur naturally or can be created by magnetising a mixture of metals (aluminium, nickel, iron and a few others) using low voltage and current and later strengthening the magnetisation using high voltage high current. so later the magnets will work even when the electricity is out, main example of magnetism is neodymium magnets and main electromagnet would the tip of a crane they use in a metal scrap yard to move ferromagnetic metals such as iron, nickel and cobalt.
if I have a box and I tell you there is a magnet inside....but you are not able to look at the inside of the box.....How would you propose to discern if it is created by a permanent magnet or one induced by an electical current?? (remember...the ONLY thing you have to work with, is the field itself....) follow-on question.....what would the criteria be for differences between the two......
Tim Hyatt i would look for wires going into the box. if there are no wires its a permanent magnet. the field is the same electromagnetism is different to magnetism by the way its created, not the magnetic waves themselves. in my last comment i was talking about the way its created.
No wires means you'd guess permanent magnet? Then I'd build it with the wires and battery inside the box, and you'd guess wrong. You owe me a drink.
Pretty neat. Instead of relying on the wire wrapping to decide the direction of spin, just start it in a direction with your finger.
Energy is motion, and friction (motion=friction) within the electromagnetic aether.
Try using some rollerblade bearings, or some of those bearings they use in bait casting fishing reels. Should be very low friction with the steel to steel.
this is amazing!! one thing i would like to point out is that regular brushed motors work underwater too
maybe an interesting novelty, doesn't lend itself to any practical purpose though. Much too inefficient. The overheating due to a high drain on the power source.
You should try this with a ball bearing ring inside a larger ball bearing ring. See if something crazy like it exponentially grows in speed the more layers you add.
+midgetconi lol, no
Baka 0ppai neither, I'm curious.
+midgetconi ah, a scientist :)
Nothing wrong with proposing an experiment, for no other reason than to see what happens :D It's generally the imaginatively impaired who like to throw around insults in response to curiosity
Ken Oakleaf I kinda want to see him use this engine in something to see how much power is behind it
you could, for fun, but if you need the efficiency and actually to build a real thing, the way motors are constructed can't get better
Maybe add some dielectric grease? Amazing how well that works! Thanks for uploading.
well, i was impressed..subbed & looking 4ward to more stuff
The most compelling explanation is via electro-magnetic forces: www.physics.princeton.edu/~mcdonald/examples/motor.pdf Needing to start the motor by manually spinning is a great indication that a rotating field is required.
Your experiment with the motor submersed in water negates much of the argument for a thermal basis. Submerged, you would expect that the motor would slow appreciably. As well, if you let the device run, as the unit got hotter (but below the point where the resistance drops the current below operation), you would expect less performance.
Thank you for the link to this interesting paper. At the time I made the video I only read Mr. Marinov's explanation which sounded totally reasonable to me. I now think that I was wrong. I will add this link to the description of the video.
F-ing awesome paper (pdf), thanks for the truth, as there's too many bogus "BS" claims. Some things actually work, as unbelievable as they are.
Yes, only the explanation you were given initially was wrong. The fact that the motor runs in the first place is amazing. THANKS for an absolutely intriguing video! Keep right on creating good stuff like this! Love it!
Mark Horstmeier
Hermann Strijewski Thank you very much for your nice and encouraging words.
I suspect that those bearings don't last too long. There must be some pitting or arc damage eventually.
Very cool (especially when running under water). I am continually fascinated by the effects you demonstrate.
+Peter W. Meek Thanks. Yes, surely. And there will be heavy radio-frequency interference. And of course they are extremely inefficent. I don't see any practical use for them.
+Latheman666 No practical use I can think of. However.... try it in non-conducting oil?
Make a video of that?
+Anthony Morris the oil surely wouldn't get between the tightest tolerances, its possible it could make it run better. Maybe less waste
I suspect you wont last long
It just killed 5 minutes of my spare time, that's practical use :)
It'd be an interesting feature in a woods hop, imagine installing it on an out feed table of a table saw. It definitely inspires when considering applications.
Nice! You’ve given me ideas. Thank you
Love this kind of stuff!! Very cool!! :)
+bluehandsvideo Thanks!
+Latheman666 i know its 12 volts, but do you know the amperage?
its basically a dead short. so it will be whatever the power supply can give you. the current that flows through the bearings creates a circular electromagnetic field which keeps up the rotation. as the current isnt very high(6A?) it doesnt self start. if the 12V supply had a big capacitor it could maybe selfstart. but there would also be a risk of welding the balls in the bearing to the outer or inner layer.
Think he describes it, above, as being 12v 4-6 amps from the battery charger on the bench
fredlllll
you are wrong fredlllll
the right explanation is at the of the video
the opening question right out of the gate: Can you imagine an electric motor that based neither on electrostatics or magnetism.
um...... then it wouldn't be an "electric" motor since electricity and magnetism are the SAME force. hence the new and improved terminology ELECTROMAGNETISM.
so let me rephrase the question another way: Can you imagine air that isn't based on air or air-like substances...? Can you imagine a set of clothes that are invisible, YET, they cover you so gently not even you will feel them against your skin.
it makes NO SENSE!!
it IS an electric motor, and it IS based on magnetism and other such electron manifestations.
you're using wires from your power supply that (gaps) generates an electrical current!
the fact it runs under water is not proof of anything other than the fact that water is not as good a conductor as the steel your little contraption is made of. in fact, the more pure the water, the better it insulates. people get a shock from water not because of the water, but because of the impurities WITHIN the water. but whatever, this is fake science.
thumbs down.
It's a standard motor if you properly apply flemmings left hand rule.
that was my thought right off the bad.....you're applying an electical current, which induces associated magnetic fields..... someone needs to go back and study Maxwell's laws...
okay, just imagine he said that it does not operate with Lorentz forces and the idea is still there.
Ciroluiro
ok, so what? the Lorentz forces are magnetic flux exerted upon an ALREADY moving electric charge! for this thing to work the guy has to spin it by hand.
i'm sorry, but i don't get why the Lorentz field has anything to do with this. the Lorentz forces are a fucking GIMME. they exist no matter what. this baboon didn't do anything special here. and using some esoteric phrase like the "lorentz forces" is what? some lame ass attempt to make us electrical types respect you?
you're a dumbass too....
+KingTesticus what? No! I'm just saying what I think the guy tried to say by saying all that. Of course it is an electric motor and magnetic and electric fields are bound to affect it, but the point was that the main effect driving the motor was the thermal expansion due to the heat.
There's no need to be aggressive.
Cool Idea,
I suspect that eventually the sparks will create minute pitting on the inner and outer races that will interfere with the running.
Great idea
man, this chanel is cool, it just poped on my recommended, and I'm all about science
0:10 Yes, it is a thermokinetic motor, nothing new about that! Make sure the water is pure or there will be corosion.
Non-efficient?
very nice interpretion of the homopolar maschine. great idea.
Thank you for sharing this video.I think it is very useful and help me a lot in working.If I need other help ,I will look for you.
it probably gets hot because it leaves a large path for current to flow
It's kinda like induction
Neil Caulfield
Tony Mak
Donn Worry MM420
put that "Motor" underload and it will weld it self that's why we has brush and brush less
Right hand rule for motors. Current flows through the axle, initiate motion at a perpendicular angle (spin the axle), and torque is created electromagnetically to continue the spinning of the axle. The electric current flowing through the bearings will quickly damage the balls and races of the bearings. This is why you often see ground straps attached to the suspension struts on your car. If ground current is allowed to flow through the bearing internals, it will wipe out your hub bearings.
That it's getting hot just means it is about the worst motor ever. You're running it with some amperes and it produces like no torque at all it's just strobg enough to turn a screw in a pretty low frequency. And beside of that the motor does of course work with magnetics and not with heat expansion because steel would never "bulge" at a spot, the diameter of the races would just increase
this motor doesn't look like I can do any actual work, and it heats up quickly which is a bad design for an engine
@motorguy81 the theory behind this motor is well understood, they use lorentz forces to rotate. play store was correct in what he said.
although the same forces are used to make rail guns (i cant be bothered explaining them to you, google it)
put them in skates. haha
I can't imagine a practical application but damn... physics is cool yo!
My boss built 1 of these at the tv station I worked at. From memory it may have been in the April issue of Elektor in 1989, 1990 or 1991. Because it was in the April issue there was discussion as to whether it was an April fools thing or a real thing. It worked, it sucked vast amounts of current, it destroyed bearings, it got hot and smoked but most importantly it actually rotated when power was supplied.
It's getting hot because it's running a monstrous amount of amperage (compared to a DC motor which uses much less and makes a ton more power).
got news for you....you're stil using magnetism...it's just electromagnetism....and it's not a "heat engine" as there's no fuel being burned..the heat your generating is from the resistance of the materials you're using..... as for the ball bearings "bulging"....thermodynamic heating of small metal objects doesn't work like that.....
Its a very inneficient magnetic motor.
Great example of Magnetic Spin through a conductor/wire. More professors should demonstrate it this way, it would be much more dramatic than using a hand to explain "The Right Hand Rule."
Dude! It's an awesome project if you're the first doing this :D I also checked ur other videos and u absolutely need more subs.. Hope u gonna have it :)
Hey I enjoyed the video. As to the real World application who cares. It is interesting to see new and diferent uses of electrical power.
Yes Walter, some people miss the point:-)
Thank you for the videos Latheman666, my students will love to see this!
+Canyon Racer there's also the application of a cheap, makeshift drill.
give that a try and see how well that works out for you......
How much torque, could it be used in a electric scooter?
No. Extremely inefficent.
+Latheman666 there is a thing that happens on variable frequency drives, where if the center shaft is not grounded the bearing will spark and put themselves. I wonder if that is the equivalent of generating power by spinning it. Have you put a meter on it without a power source and spun it at high speed?
+Timber Wolf pit* themselves
1) submerge it in oil
2) add a CVT
3) add starter that spins in both directions
4)???
5) profit
That is why he added the CVT ....4 2 compensate the cool thing about motors like this is what it lacks in torque it makes up for in submersability hello under water fun!
Realy intresting work
hows that not based on electrostatics lol
Maceto because the motor is not driven by the electromagnetic fields in any shape or form. at the least the engine can be simply explained with mechanics of materials. The engine is driven by a constant cycle of changing tensile strains within the bearings themselves that are caused by temperature differences in them. this heat can be either directly applied to the rings of the bearings or dissipated by an electric current.
once you plug something to a wall it becomes electrostatics driven one way or another
reminds me of ur mom, just get her started and she'll keep going.
well said.
Gets hot pretty fast tho
socar128 kinda like her ;)
his mom kept going but you stopped after a few jabs. (^~^)
This is so cool! Have you tried larger bearings and measured the RPM?
Cool mini wrench
so this thing is use to boil water rite ?
wat
It can is used to youre welcome
Johan Rosly
😂🤣
hate to break it to you, but you are still using electricity, which is magnetism.
Thegreata891 put a compass up to a wire with an electric current. it's not exactly magnetism, but it's electromagnetism.
Hate to break it to you but electric current (electricity) CAN induce a magnetic field.. but there is a big difference. Besides his design is not based on any sort of magnetism
It was Published in a magazine more than 25 years ago in Electronics
There was a man from Santa Barbara who invented a motor called the N-Machine. Using these simple and powerful concepts the machine ran these concepts to the limit. He was often mocked and was never held in high esteem, probably due to politics, or at least that's what it seems to me. Often times there are different ways to accomplish a task or to explain a particular phenomenon. It may appear to be or even be an inferior process; however, such things can still be used and learned from.
It even runs on a highway to hell... I'm sorry I'll leave
jak1259 AC/DC is shit
not shit, but over rated.
Somik Datta compared to your Indian music it's 100x better
acdc is good
Kylen Phillips Aqy
I have failed to see the point. An inefficient motor that requires electricity to run. Now that's something to write home about. Mostly I am curious as to your nickname. Why the 666? No need to answer if you don't want to but I am quite curious.
This motor is interesting mainly because it uses thermal expansion of the ball bearings as the driving force of this engine.
Erik Peterson Hey, thanks for the comment. Appreciate someone actually explaining it as opposed to some bs smart ass reply :)
That's the claim in the video anyways. Whether or not the claim is true is another matter.
rockethead555 I was hoping for his answer. I could have just as easily made my own assumptions but whereas it is his nickname I asked him.
+Erik P : has nothing to do with thermal expansion of the bearing. you should have guested it when it was running under water.
it is just a cool diy electrical moter. I enjoyed watching as a diy projects/toy but the explanation is way off.
many theorists say the ball bearing spins because of expansion and contraction from the shorting of the round balls, i refute these explanations and believe they are actually caused by electromagnetic pulses that occur withing the contact circumference of these bearings.
Awesome. Thanks for sharing this
LOL,,,,what you have there is a dead short. It's not going to turn.....
Dc buddy, one series path.
but no resistance, still a short ac or dc
of course there's resistance. and it will turn just like any homopolar motor will under the same 'dead short' scenario.
Cool but your explanation is wrong.
Brilliant! I was searching for an electromagnetic explanation (you don't need coils of wire or permanent magnets to get the effect). I failed. It's a kind of heat engine. Thank you so much!
oops! I just re-visited this video and saw latheman's ref to the princeton paper. So it's em, not a heat engine. btw you can make a motor which is powered by electricity without using either em as mechanical force or electrostatic. An electric heater powering a sterling engine.
Cool.
Too much PhD's comments but, no one proving their thoughts like you've done. Congrats!
Much as I love to know the 'why' of a thing's workings, in the long run, if it works - and it obviously does - does the 'why' really matter? I see many fun/interesting uses for a larger version of this. Thanks!
As another comment, I just realized how useful it could be to send a low power signal through the barings. Simular to how some devices have screens that can flip around once. maybe this could fix the delima of the reversable screen. You certainly would never have to play with messy wiring between the two physical components.
So many comment here stating this is an induction motor, magnetism etc...
This actually does not work with magnetism. It works with heat.
It was already explained in a1968 physics magazine that I had.
The high current required heats the the tiny spots where the balls make contact with the races and the metal expands there pushing the balls along.
That was so simple yet very impressive. How did you come up with that? Just curious.
I would say it operates on eddy currents, but it's a neat effect.
Love that miniature adjustable wrench! LOL
I am curious about the rotational torque/speed chacteristics. It appears to create a lot of heat, and those curves would be interesting data for comparative analysis, for determining utilized power efficiency.
Still, a neat trick...
does it still move with a load like pushing a fan blade lets say?
fantastic. I can hardly believe the simplicity.
Nice idea ! How did you solder wire tips to the outer rings ? because usually outer rings are made of steel not copper?
I think there is more than what eyes see. And maybe we are not seeing the method we should use to run it efficiently. In example: if you take a transformer and a capacitor and make an LC circuit with the primary, then on the secondary you connect this motor (= short circuit) the impedance of the primary coil will drop and the current will flow like if no coil is there and the capacitor will limit the amount of current flow. At the same time on the secondary you have full amps flow that that specific configuration can provide, so it run run fast, with little current consumption on the primary. To avoid or drop the temperature, use bearings of one material and a shaft of other material (maybe bearings of steel and shaft of brass) making a Peltier effect. Use different configurations of materials until you find the one that keeps the bearings cold. Hope this make any sense.
That very cool Thanks for sharing
There is a great application for it - to heat your tea and stir it at the same time.
that was some nice stuff
Have you done a "to failure point" video for this set up? Have you tried this on sealed bearings? This is a very interesting channel and it clearly deserves a subscribed.
would it run under a load like the bolt turning a belt or fan?
unpractical but very cool!!!! At least people are experimenting and using their brains! Thanks for the video.
That's what I was looking for. That design. Thank you.
For your new book: "What NOT to build" ?
It's complicated. I don't want to share the idea at this moment. Maybe when I finish it.
Sounds promising.. Please keep us updated.
Why not, afraid no one will care?
Do you think that the bolt could be up scaled to be a drive shaft? Or is there way to little torque?
Wow interesting, what happens if you run them continually , do they heat up an melt, seize or does a coolant need to be applied for continuity
Would this work if your wire connections went to the inner races and spin the outer races? non conductive bolt or coating, with a connection between the 2 outer races maybe?
this is a cool simple little design for a small engine. good idea bud.
They pull tens of amps
Martin O'Donnell
i didny say it was cool because it was efficient it is just a simple cool design made with household items.
Actually, it's a pretty _hot_ little design...
can u reverse the setup and use a longer bolt so u can connect it to a drill and connect the red and black wires to a multimeter to see if it generates power. thanks in advance
Fascinating!
Very cool stuff !!
Have you tried driving the shaft and checking for output?
Could you power the centres and the outsides of the bearings would work as very weak wheels or no
MOST EFFICIENT BUILDED MOTOR EVER..GREATE
Because it is such a great idea to have arcing across a bearing surface. Also RCD isn't going to do much when you are using a transformer.
could try wraping the wire all the way around casing to ensure even voltage or at opposite point...
a pair of heat sinks attached to the bearings may help with a fan blade?
Can you make outside spin like on metal pipe etc??
