Brushless motor with electronic commutation - Hall Sensor. Neodymium Magnets 20 x 3 mm - ali.ski/GgUm2 Hall Sensor A3144 - ali.ski/4LwL5 Transistor IRFZ44N - ali.ski/JtE-hs
Thank you, I'm very touched. I have been busy with other work recently, there are more financial prospects. But I'll try to make new videos, though less often. I have many ideas and plans for video and even bought a lot of materials for this.
*Посмотрев на колесо с магнитами вспомнил случай, мой дед рассказывал в молодости у него друг был, тот создал газовый вечный движок он работал на разности температур. Пол установки было закопано в земле а половина нет. Так вот, он не продавал это и не пропагандировал ничего но был очень общительный и об установке знал весь поселок. В итоге получил срок. Так вот Grain если в ходе эксперимента что то начнет работать само по себе лучше это утаить* 😁
Этот макет мотора - мотор Минато (патента США №5594289 14 января 1997 г., в котором японец, бизнесмен, Кохеи Минато описывает принцип действия аппарат магнитного вращения), ничего особенного тут нет и ещё бы лучше работал, если бы как и в патенте Минато автор видео использовал бы два полюса электромагнита, а не один. Подобные моторы (с одним полюсом) делал как игрушки, только у меня сигнал на включение электромагнита брался с геркона и через триггер Шмитта (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hcNLolWz4nw.html)
It is supposed to use the MOSFET B-GEN so that it does not get damaged because the sensor gives a negative pulse to the MOSFET gate while it needs a positive pulse. I did an experiment through my channel and drew the circuit

Я один из ваших постоянных подписчиков, и ваша кропотливая работа поражает меня, и я надеюсь, что, если вы сможете продать мне это произведение по разумной цене, у меня останутся важные воспоминания о самых важных творческих людях, которые появляются в социальных сетях. При всем уважении, желаю дальнейших успехов. @назар.
Спасибо за такое лестный отзыв, но я давно разобрал данный девайс, впрочем, как и многие другие. В 2021-м году я делал еще несколько разных моторов, все они также демонтированы.
I have made this circuit on many occasions and it works beautifully. I have just been wondering what would happen if a pull down resistor is used with the hall output instead of pull up. Would the output simply go high instead of down when the magnet passes by or such configuration would conflict with the hall's internal circuitory? As always I appreciate everything you do.
If you were to invert the signal from the hall effect sensor, I would imagine that the placement of the sensor would need to be 180 degrees out of phase from where it was previously.
I buy such coils on the market of old things in my city. But it's not at all difficult to reel the coil 300, 500, and even 1000 turns using a wire from an old transformer or motor.
Great 👍 You're the best. Can you make a perpetual engine(rotation or piston movement)؟ With permanent magnet and without electricit power. ( completely mechanical)
Если можно،вы можете мне посоветовать так как у вас есть опыт и в результате постоянного трения с машинами складывается отличное от теоретической науки представление. У меня есть железное колесо над которым я хочу провести эксперимент.Вы мне советуете вращать это через магнитное поле как по вашему опыту, или вы мне советуете вращать его механический Через ремень ; 24в двигатель вольт, и в каком из двух случаев экономить энергопотребление? Спасибо
Thank you so much for this, it answers a ton of questions I have for my project, I cant tell you just what it means after a great deal of time researching. Subbed, liked. (Im guessing the mossfet gets pretty hot?) What guage wire was it? around 23swg? and the LED also acts as a Fly Wheel.
Other RU-vid channels, sites, something from my school hobbies ... Sometimes I invent myself, but most often I transform, modernize or supplement someone else's idea.
Hii, iam inspired from this circuit, implementing it in magnetically levitating wind turbine which is utilising only permanent magnets and eddy current drive with tungsten carbide, will upload it soon Inspired from Nicola Tesla
G,day Grain your videos are great i have enjoyed doing a few of your projects .. i have hit a brick wall with reading the electrical diagram .. i am stoked you put the wiring diagram up .. it is just that i cant understand the mosfet transistor diagram .. do you have a video of you soldering up the wires on the mosfet transistor and hall sensor .. i have all the right componentsi have tried pausing your video and copying your wiring but no good .. any help would be most appreciated
Thank you! You can use any conventional bipolar transistor with an allowable voltage and current, for example BD139. How to connect IRFZ44N - anod7.ru/files/IRFZ44N.png
@@grain-diose He is asking that if you had each wire in different colors some folks do, it would be so much easier to follow which wire went where if a person stopped the video and or any schematic?
i was asking about the colour of the wires from hall sensor to the mosfet switch ... i have a red , green and black wire .. i just wanted to know what colour wire connects to positive and what colour connects to negative as i have little know how
In this case, you can use any Hall sensor, you just need to know / determine where its anode, cathode and how it reacts to the magnetic field (north / south and distance).
grain Oh thank you for the response! Are the magnets alternating in polarity? For some reason I assumed the same polarity was facing outward all around (but would that still generate ac?). I'm new to this, lol, so thanks again for the response!!
Take the tube with an internal diameter of 22-25 mm, wind 500-1000 turns (or more) with the thinnest wire that you will find. Take neodymium magnets 20 mm - aliexpress.com/item/10pcs-20-x-3-mm-Super-Strong-Rare-Earth-Disc-20mm-x-3mm-Fridge-Permanet-Magnet/32799951088.html Connect the LED and then move the magnets by hand in the coil and you will see it yourself.
If you can not find the wire you can buy it - aliexpress.com/item/Sample-0-1mm-1000m-pc-length-QA-1-155-Copper-Wire-Copper-Line-Enameled-copper-wire/32628561928.html
I am wondering when the magnet passes by the sensor, does that cause an electric current ( energize the coil) to go through this type of MOSFET (NPN that is), or does it stop the current ( de-energize the coil) that was already going through it when the magnet wasn't by the hall sensor? ( I suppose that would mean by default the NPN MOSFET passes current through it). If this happens to be the case, wouldn't it make sense to use PNP MOSFET instead so it acts like a reed switch as when the magnet passes by the hall, the MOSFET lets current flow through it and the coil is energized at that moment and pushes the magnet? I am confused as always. And thank you for everything you do.
1. The pole of the coil and the poles of the magnets are located at repulsion (if the transistor is open). 2. From the video at 1:36 it is clear that in the absence of a Hall sensor, the transistor is on. 3. When the magnet is in the sensor area, it opens and it closes the transistor. The coil is turned off, the rotor is coasting. 4. The magnet leaves the sensor area, it closes, the transistor opens, the coil turns on, the coil repels the magnet that is nearby.
@@grain-diose I did make this set up back when I first watched it. Except I put my wheel horizontal and I played with it moving it by hand to see when the coil is on and off and for how long each duration. The coil seemed on for more stretch of time and than off-time. I felt the coil should only be one when it needs to for a brief moment when the magnet just passes it, not on it, and certainly not before it ( depending on if one want attraction or repulsion). I noticed I was able to get only so much RPM out of it which wasn't that blazing by any means. I made my disc from the top of a plastic bucket and I placed 12 (N52 Magnet 3/4 inch). I placed the hall right where I could get the most bang for the buck by using my hand mechanically moving the disc to see. Come to think of it, I don't think I tried the reed switch with the setup to see if I would have got more rpm. I should try that to be honest. I also wonder if PNP MOSFET (IRF 9540) will turn it on as the reed switch, just at the time when it needs to, to see if it works better and get more rpm, or combine your transistor with an NPN 2N2222. Maybe it will go faster plus maybe will keep the coil stay cool and not be on when it serves no purpose. I don't know. Looking at your disc at the moment, seeing its circumference, by observing the size of your magnet 20mm = 3/4 inch, and the distance between each magnet, gave me the answer. The distance between two magnets is hardly any more than the size of the magnets. Yep, my plastic bucket lid too big. :-) The diameter of my bucket lid was a good foot and even with 12 magnets, there was probably 3 times more open space than what I see with yours. It seems I have used the same size magnet as you do and looking at your disc it would take perhaps a little over 16 over your magnets to cover the entire circumference of your disc. Meaning the circumference of your disc is roughly one foot which means your disc is hardly over 4 inches (10 cm) in diameter. My disc 30 cm in diameter. Go figure. That is my detective conclusion, details never caught. I also don't know what the numbers on your coil mean except the turns of course. l like to know the size of your wire if it is less than .5 mm or? I assume it is Russian size or? Thanks for everything you do. I like your presentation style of all your videos.
@@alchemy1 Don't forget one thing, that both the sensor and the transistor have their own opening and closing times. This limits the maximum RPM. However, MOSFET can operate at frequencies of tens or hundreds of kilohertz, but I was not interested in the opening time of the Hall sensor. Ask if this is an RPM limitation. In any case, I also achieved a not very high RPM (I did not measure it), in the video you see the maximum - 2:20 By the sound you can understand that this is no more than a few thousand RPM.
Да, можно расположить вообще 8 катушек - на каждый магнит. Конечно мощность и эффективность возрастут кратно. Но такая цель не ставилась, я ведь не производством занимаюсь, а просто показываю принцип работы.
Я имел ввиду другое - вторую сторону катушки. Позвольте оставить ссылочку ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Q90EfYu9Btk.html и вот ещё ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-c4S_gV_aBdY.html
This is a coil from an electrical board, I bought this from the old things market. But there is nothing difficult to wind 300-500 turns of wire. The coil frame can be made of cardboard or plastic.
By the way, the simplest and most qualitative solution is to use as a rotor fidget spinner with three magnets. This will be a better solution because the rotor centering will be more accurate. If you watch the video carefully, you will understand that my rotor centering is not good. This can be understood by the sound even. The test engine I made from the fidget spinner and there was no such vibration. But I made too many motors from the fidget spinner and I decided not to repeat this method. And yet: be sure to wrap the rotor with adhesive tape along the radius. Otherwise, at a high speed, the magnet will come off and may cause injury to you.
so its reverse pole sequence, sir i guess next u should mark magnet polarity for better beginner understanding like me, next make a reed switch trigger motor..? yesss...!!!
I am one of your permanent followers, and your meticulous work amazes me, and I hope that if you can sell me this piece at a reasonable price, I will have an important memory of the most important creative people who appear on social media. With all due respect, I wish you continued success. @nazar
