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.
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".
@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.
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.
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.
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?
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.
@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.
@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 ! =]
@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.
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.
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!
@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?
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
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.
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.
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!
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.)
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.
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.
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.
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?
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.
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.
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.
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.
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.

Where do i get the wire?
james4562000 1 year ago
@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.

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 1 year ago
@teC5
Yes, a 1" neodymium of grade N52 is probably the best choice for this experiment!
MrfixitRick 1 year ago
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?

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 1 year ago
@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?

What would you use a motor like this for?
justindavidlake 1 year ago
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.

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
