  • I am very happy to see the vidoe after you give this The World's Simplest Electric Motor, the homopolar motor, can occasionally overheat or fly apart during over-enthusiastic experimentation.

  • I Love The Video It Can Increase My Knowledge The World's Simplest Electric Motor, the homopolar motor, can occasionally overheat or fly apart during over-enthusiastic experimentation.

  • Steady I Really Like This Video Steady I Really Like This Video

  • Good, I like that you share this video Homopolar Motor With Emergency Brake System , I wish success always

  • Nice Video The World's Simplest Electric Motor, the homopolar motor, can occasionally overheat or fly apart during over-enthusiastic experimentation That You Share , So Very Nice Thanks You

  • I Really Like The Video From Your The World's Simplest Electric Motor, the homopolar motor, can occasionally overheat or fly apart during over-enthusiastic experimentation.

  • Your Video Is Very Useful Sharing Homopolar Motor With Emergency Brake System

  • How did the chillies taste after this?

  • thanks for share...

  • OLD EL PASO! xD

  • Any relation to Steven Wright?

  • Holy shit. Automatic Breaking System? ABS?

    or did you just mean a piece of bent wire?

  • @Gunner3210

    Automotive ABS systems are all about "bent wire". The magnetic speed sensors are made of a bent copper wire coil that a magnet passes over. The brake system computer with a bunch of bent wires inside controls the pressure into the brake lines, which moderates the braking action.

    I have simply replaced the ABS CPU with a tin can ;)

  • @MrfixitRick You are mistaken. Modern ABS systems use hall effect sensors which are actually made of composite of semiconductor crystals. I assure, there has been considerable effort, research and technology that goes into producing these sensors. These sensors are extremely reliable and accurate.

    Even the older coil pickups you are talking about are very much more reliable than your bent wire. As a demo, it's fine. But it is a far stretch to call it a "Emergency Brake System".

  • @Gunner3210

    I guess this means my dream to be a millionaire by selling this design to the auto sector is out??

  • @Gunner3210 ABS does not usually stand for "Automatic Breaking System", it actually stands for Anti-lock Braking System. Just to let you know

  • @safc44 Thanks for telling me something I already knew. I know exactly what ABS really means. If you watch the video again, you will notice that the poster calls it "automatic braking system". I just sarcastically called it ABS.

  • Is that a neodymium sphere holding the whole apparatus to the stand? And do you use rechargeable batteries?

  • @Zoidberg227

    Yes and yes. 

  • homopolar are gay

  • @NaderX77 homo sexual and homo polar are 2 different things. homo just means same.

  • @AgentRikuOfficial actually it was just a bad joke

    but i didn't know that homo means same so thanks

  • @NaderX77 lol

    no prob

  • homopolar lol

    

  • so it more or less works under the same principal as an alternator

  • @guccamain

    The same principle of the Lorentz force is involved with the inner workings of an alternator.

    It is a different idea in that the alternator uses motion to create alternating current (AC), but the homopolar motor uses direct current (DC) to create motion.

  • @MrfixitRick thats pretty cool

  • bahahahahahahahahahaha

  • Is the battery expires?

  • @teelme99

    The battery will expire in several minutes.

  • Troll

  • Hey, thats a new way of opening a can, yaaaaaaaaaay...and nobody thumbs up this comment...

  • i hope you get to the point where you make pulse motors that generates more 80% output from 10% input

  • @CariagaXIII

    That's a good thought...and it may be possible.

    After watching over 15,000 Youtube videos, I have yet to see more output energy from a motor than input energy. However under the right circumstances, I think it may happen. 

  • @MrfixitRick please tell me how can you make more power then you input to a motor. that would rape the physics itself.

  • @MuF123

    As an example of a motor that appears to put out more power than input, would be a Thorium-based reactor engine. It requires initial power for the electrical/magnetic fields to start and keep the reaction going, but would output considerably more power than that input power. (no physics laws broken, just revisited...google "thorium car" for more info ;)

  • @MrfixitRick starting a regular car engine requires just 12V battery and then it produces way more energy than the battery put in the engine, you know that right?

  • @MuF123

    Good example, except with a regular car engine, you have to keep inputting energy by refilling the fuel tank.

    A few grams of thorium, equaling the energy of tens of thousands of gallons of gasoline, will run the thorium-based vehicle for a lifetime without refilling. Thorium is about $25 a kilo.

    Besides, thorium can be very safe to use and it can't be made into weapons. Thorium is as common as lead in the Earth's rocks and soil.

    Cool, eh?

  • @MrfixitRick Oh yea, filling the fuel, that's what I forgot. I'm glad that there is no need to add thorium to thorium reactor! Because if you had to add thorium to thorium reactor, it would be fuel too.

    I sincerely don't care about how rare it is, how much does it cost or how long will it last. It is FUEL.

  • @CariagaXIII then just hook it up to  generator.

  • FUAAAAAAAAAAA COMO AGO ESOOO ?¿ JIJI TA BUENISIOMO

  • This thing has NO torque does it.

  • @frostcat123

    It would not begin to run at all with NO torque. It has minimal torque, but is a small motor.

    The naval ship homopolar motors are 25,000 horsepower...with lots of torque! (google "naval homopolar" )

  • Would there be a way for the wire to move back when its juuuust under the speed limit, that way you can maintain the top speed?

  • @Jaramo1

    The top speed can be maintained with careful adjustment. However, if there is vibration, it tends to kick in the built in brake/governor.

  • A more mature joke then?

    im almost married for 13 years, so that makes me pretty homophobic.

    And for those who didn't get this:

    Wedding cake breaks down the sex-drive of women.

    and you can get it without a prescription.

    Back on the "Homopolar Motor With Emergency Brake System" dare you to place the battery on a floating device and whip up some cream with it.

    perhaps the fluid can function as a conductor? i doubt this would pass enough current through it to work..

  • Homomotor !

  • @PandaMagicFTW

    Here we go again...;)

    (see previous comments regarding homogenized milk)

  • @MrfixitRick Yes yes it means, a similar polarized motor I'm guessing. The name just sounds funny, because you sounds like homosexual, like a homosexual motor. Homomotor ! =]

  • @PandaMagicFTW

    This gadget can acually cure homophobia!

  • is there any possible way to do it using a 9 volt or will it be too unbalanced and be quite useless?

  • @MultiIpodhelp

    Using a 9 volt is possible, but will be "unconventional" as to design and likely "unbalanced'. I'll try it in a future experiment!

  • @MrfixitRick Just wire the neg or pos pole down to a plate magnet on the bottom, then toss a round magnet over the plate magnet. On top insulate whichever pole you drove down to the bottom and put a stick magnet across both, should be able to balance it pretty well with a properly polarized ball or dome shaped magnet in the middle of the bar.

  • OlDelpaso it's a fiesta on magnet

  • Tic tok tic tok tic tok lol

  • DO you need that certian type of magnet or will any magnet owork?

  • @kickass4510

    The only magnets that are strong enough and cheap enough are neodymium supermagnets. They are available online at a place like K&J Magnetics (see link in the "show more" box) or take apart a shake-type flashlight and use the magnet inside.

    Depending on your motor setup, you can use a 1/2 x 1/2 inch magnet, up to the 1 inch x 1/2 inch size seen here.

  • @MrfixitRick Cool... i have to make one of theesse

  • ha! he said homo! jk

  • @kickass4510

    You must have a good laugh when you ask for "homogenized milk" !

  • @MrfixitRick i was joking lol this motor is cool... i still dont understand how this motor works

  • @MrfixitRick This should make him pee his pants:

    Some homosapiens or homogenates do drink homogenized milk bought at the homo-gene market where you can buy lots of homo genetic foods. Perhaps his parents are homozygous and share the same homozygote gen? but back on the engine, its shaft could be made with a homo kinetic coupling so the rod doesn't wiggle the homopolar engine so much...

  • @Voyeurisnotiseur dammit! I didn't find the homo "jokes" funny till you wrote all that. I actually started to crack a smile by the time you got down to the wiggling homo coupled rods and what not ugh I blame you for making me turn into a 13 year old for a moment!

  • @kickass4510 I bet you laughed at "vibrate" too... grow up.

  • @doncurproductions2 no i didnt. i was making a joke i didnt actually meaan it i didnt find it funny at all. on another fact how does the emergency brake actually work?

  • can you make a can opener with that

  • @elielpopoca08

    This apparatus doesn't have enough power to make it into a can opener, but with a big enough magnet, it could certainly be done!

  • Oh...My...The battery is overheating! There's going to be a catastrophic meltdown!!! Oh thank goodness it has an emergency break. Wtf?

  • you sound like steven wright

    

  • It looks like a complicated can opener

  • @mitchabusa1 theres the problem, i dont like buying online. and its ok to be a smart ass with me my teachers hate me for it [insert troll face here]

  • that definitaly not a emergoency brake ahahah get it get it LOLLLL THAT NOT A EMERGOENCY BRAKE it an EMERGENCY BRAKE

  • that break would "break" your battery if you would not touch it after stopping :D but it's  very interesting and Im impressed by speed and mechanical performing especially:P

  • try attaching a fan to it...

  • where do u buy ur neodimium magnets?

  • @jorgelopez0911

    I prefer to buy neodymium supermagnets on-line from K&J Magnetics. The link is found in the "Show more..." box.

  • @MrfixitRick ok thanx!!

  • 1:37-1:40 look closely at the right side of the lower magnet and you will see a small spark.

  • @BIBbib123456

    The sparks from a homopolar motor are interesting. The battery is only 1.4 volts, which should not produce much of a spark, yet the sparks are often clearly seen. There is a high current draw and it is likely there are bits of nickel and neodymium burning off.

  • @MrfixitRick maybe the sparks are from the coil that you made in the copper wire.

  • @themassau

    The sparks also occur with other non-coil designs. Although the wire itself may be partly the cause, it seems more of a commutator on the magnet issue. It would be a good experiment to try a copper sleeve around the magnet's commutator contact surface.

  • I've seen homopolar motors before, but this is by far the best.

  • Anyone else found this video in the suggestions bar for a Hammerfall song? :D

  • If you used a full can, how fast would it spin before it blew up! :-))))

  • @ChuffChuffWoo

    I figure a full can should go at least 80,000 rpm before it explodes!

  • @MrfixitRick YUCK!!! ;-))

  • use a lithium battery next :D

  • @DAKODA65

    I can push it, but the di-lithium crystals might overheat, capt'n!

  • That could make a really good fast can opener.

  • @USMC17751

    Haha, funny! It's true that homopolar motors can be very powerful. The latest navel ships are using twin 25,000 horsepower electric homopolar motors that are supercooled, superconducting...and super quiet!

  • @MrfixitRick Yea sound is a differnce between life and death in certian situations.

  • lol not auto braking system just failiure in constructing motor sistem.(srry for my bad english hope you got the point.)

  • @edulitto1

    It took a couple of hours of my attention to get this to work right. It was not a failure in motor construction. Get the point?

  • NICE.

  • Or you can hit it all down with your hand ^^

  • Its able to.. freewill quite freely, great observation!

  • Green chiles! :D

  • cool

    

  • que es la volita de arriba?? un imán...?

  • @daarcksiidee

    sí, es un imán de bola en la parte superior

    (ye, it is a ball magnet at the top)

  • This is a great experiment! My son wants to do this for a science fair project. Would you please give me a specific parts list, or any references for where we could get the scientific info behind what makes this work? (I'm so new to this that even volts vs. amps sounds alien to me.)

  • @Crunchy68

    Parts List:

    Steel Coat-hanger

    14 gage solid copper wire

    3/16 inch ball magnet

    Heavy Duty AA Battery (rechargeable Duracell 2650 MAh NiMH shown)

    1 inch x 1/2 inch neodymium magnet

    Chilies tin (empty)

    For info, check out Wiki under "Homopolar generator" and see my other homopolar motor movies!

    Good Luck!

  • @MrfixitRick Thanks so much! I would not have been able to guess all that on my own (especially that the can was empty - clever!)

  • this looks pretty stupid, but in terms of control engineering it's actually correct and works hahahaha

  • @cheBeto0

    Thanks; it's hard to get to the essence and engineer simplicity!

  • Thanks!

  • If you used a Joule thief with a 1.2/5v battery, would you get more RPM?

  • @a4d2d0

    The speed would depend on how much power the Joule Thief can put out at it's higher 4 or 5 volt abilities.

    Generally with homopolar motors, the higher the voltage, the faster the speed, and the higher the amperage, the more torque. But this set-up requires a couple of amps to get it rotating and overcome resistance; it will drain this heavy-duty 1.5 volt battery quickly.

    If this AA battery had more voltage, and was able to maintain the same amperage, the device would rotate faster.

  • GREEEEN CHILIEEES! : D

  • MISTER !!!! u should work at black mesa !!!!

    i bet with u the teleporting experiment would ve benn worked perfect !!! :OOO

    xDDD

    douchebag xD

  • You know how I know you're gay?!...you play with homopolar motors.

    :D

  • @donsjuand

    And you drink homogenized milk, right, haha??

  • @MrfixitRick Hehehe :) I roll with the 2% so I guess that means I'm NOT gay?!

  • @MrfixitRick LOLZXZ THUMBS UP

  • ive never heard a can of old el paso green chiles called a device before lol,  nice design though!

  • What determins how fast these things can spin? Higher voltage? 

  • @intheshitter

    Yes, the voltage determines the speed. The torque is related to the amperage.

  • Nice one ! I would like to see it funning as fast as possible :PP

  • @OnnomonnomonnO

    Some homopolar motors can go up to 10,000 rpm...;)

  • this guy doesnt even tell us how it brake itself when the gear is shifted all the way up. pretty sure it doesnt know what hes talking about

  • et sinon t as eu la chiasse avec la bouffe mexicaine râââhahaha :/

  • great!

  • 77 people dont like old el paso

  • Ok, Sorry but when is there EVER gonna be a time where your motor is in an emergency situation?

  • Homopolar vibrates? What the fuck is this machine?

  • @Djrepsaj

    The word homopolar refers to this type of electrical motor...it means uni-pole or single pole. Most motors have a segmented commutator, or use electronic means, to rapidly reverse the magnetic poles to keep the motor running. The homopolar motor makes use of Faraday's Law regarding force on a rotating conductor in a magnetic field.

  • you should make the brake work from the opposite side that way it will start back up after it slows down

  • is there a switch ??

  • @dajakesta1234

    The only "switch" is the copper wire connection to the magnet, which gets "tripped" like a circuit breaker in this case.

  • In the description you say that the rod "senses" vibration. But there is nothing sensing here. It is simply harmonically moving to the end of the coat hanger. Just clarifying.

  • you know the homopolar motor is gay when it goes to fast.

  • You are cool

  • From where can you get the steel wire?

  • bet you made the brake system on accident

  • hey,gotta a question,why or how is the battery hanging? how do you do that? does it have a magnet in the bottom? I used all the materials you say u used except for the thing in the bottom and could not make it work,i scrapped and sanded the copper wire,what did i do wrong?

  • @drummaniaco

    I used the most powerful N52 magnet below the battery.

    The battery is magnetic (note:some batteries are NOT magnetic enough to make this work.) The magnetism goes through the battery and allows it to hang.

    The heavy-duty hanger wire must be smooth and rounded where the battery contacts it, not a point.

    Use a tiny magnetic ball if you have to.

    It wasn't easy, as it's all at the limit!!

  • @drummaniaco

    Also, the hanger wire is steel, not copper, and it must be scraped of the varnish coating so the copper wire makes contact with it.

  • Homopolar? How do you know the motor is gay?

  • I also have an emergency brake system, flick the battery...

  • i like the part where it spins

  • lol in dutch homo meens gay...

  • @ultimecia124

    I guess you have a laugh with homogenized milk, too ?? (hehe)

  • @ultimecia124 guy in every country homo means gay... in colloquial language....

    here is meant "homo" like "equal" (from greek ὁμός homos „equal“)

  • @ultimecia124 guy in every country homo means gay... in colloquial language....

    here is meant "homo" like "equal" (from greek ὁμός homos „equal“)

  • @ultimecia124 pretty sure homo means gay everywhere...

  • thats mint i would love to make 1

  • i wouldnt want it to slow down

  • Where do i get the wire?

  • @james4562000

    The hanger wire is a standard metal coat-hanger. It has been scraped and sanded where it makes contact with the copper wire. The copper wire is # 14 gage wire, found in household wiring.

  • now make a car.

  • BABY JUNK!

  • nice...

  • Lol boring xD

    If you don't want the thing to go to fast why don't you just:

    A. Use a less powerful battery

    Or

    B. Put a resistance in the circuit?

  • would a Grade N52 (neodymium), about 1" diameter do ?

  • @teC5

    Yes, a 1" neodymium of grade N52 is probably the best choice for this experiment!

  • put on the outside ring something tape. So it jumps on the tape and has no contact ;-)

    nice work u rule the world soon

  • Can I use any kind of magnet? because I can't find any neodymium magnet here in the Philippines.

  • @stitchloveslilo

    Most magnets are not strong enough. If you can find a shake-type flashlight, they have a neodymium magnet inside. Or, you can order magnets from K&J magnetics...link in the "more info" box.

    Here is another option to make a homopolar motor using a big bass speaker magnet...there should be lots of those in the Phillipines! Check out my movie "Two Hearts Become One" watch?v=nERQQl7KlHc for more about this.

  • @MrfixitRick thanks

  • @MrfixitRick o wow i always thought the super strong magnet from my shake flashlight was a iron magnet, so it is neodymium?

  • @stitchloveslilo haha Fail ka pare lol sirain mo nalang yung refrigerator

  • You need to get out more

  • how many Hp ? :D

  • Can you help me? I need a high speed braking system for my blender.

  • If it overheats put a resistor in it so that it does not have so much current going through it. Your battery will last longer too.

  • You should add something to make it start spinning again...

  • Would the hanger be able to support the tin if it was full, along with everything else it has to support?

  • @worlddomin623

    A full tin would be too much weight for the battery as a magnet. It could, however, be supported by placing a ball magnet between the hanger and the battery + terminal.

  • How about putting a soft spring on the sliding copper so it can maintain a safe speed instead of stopping every time it goes too fast?

  • How about putting a soft spring on the sliding copper so it can maintain a safe speed instead of stopping every time it goes too fast?

  • amagin 1 of those with a d battery lol it would be like a helicopter flying around the room!

  • What would you use a motor like this for?

  • It was such an accident that he even discovered this "automatic braking system" in the first place. He couldn't get the motor's "brush" to stay in place so he decided to make the best of it and call it his "ABS".

    It's not bad or anything, but this guy needs to stabilize the base.

  • @654magicman

    The parts are:

    1.) a strong battery that sticks to a magnet (Duracell NiMh rechargeable 2650 mAh are best.)

    2.) a strong neodymium magnet about 3/4 x 1/2 inch

    3.) a steel coat-hanger or welding rod as a stand.

    4.) a 1 foot piece of copper wire to wrap around the stand and touch the magnetnet (scrape the hanger for conductivity)

    5.) OLD EL PASO Green Chilies tin, empty

  • OLD EL PASO

    Green Chilies

  • Should build a way for the break to automatically reingage after the motor slows back down....

  • i was expecting it to automatically stop not slow down drastically... very good though

  • EEXXEELLEENNTTEE!!

  • thats no automatic breaking system

  • What is this cable?
