Big thank you for watching this video :)
Please check out the making video. Part1 : th-cam.com/video/JWPxP2uuCJ4/w-d-xo.html
Have a great day :)
You should try heat treating the rounded cover to see if you can clear it up.
So it cost what?
How do you control power supply
U ONLY NEED TO BALANCE IT TO A SMOOTHER ROTATION.
Почему бы не сделать полноценную функциональную модель двигателя, а не его часть?
Next up: Flying a plane with a micro radial engine.
Flying a drone with radial engines!
@@aaronatherton7431 I'd watch that
So would i
Tom Stanton, take notes
This would probably be too inefficient or battery draining. But I’m down to see it
Maker B. The only person that would build a micro radial engine to cool his coffee.
I wanna see him make a whole airplane at that scale with really scaled doen plain parts
Incredible machine work and craftsmanship. The engineering and precision involved to produce such intricate parts is truly superb. Very enjoyable to watch an expert at work!
Thank you for the kind words!
He has heard our pleas, and we are grateful to him
Hear, hear, Grom !
Airoplaneeeee
Ask for larger portions at lunch.
Absolutely.
Awesome 👏
Love how it starts up kinda rough then smooths out. You'd think it was running on gas. Video is excellent.
thats what i thought as well^^
Its called a lope in diesel terminology. 💁🏼♂️
You deserve that cup of coffee, great work! I’m subscribing!
Honestly?!
In terms of explaining, building and giving this to us, you are an ARTIST! THANK YOU MAN! 🍀👍😃🍾🌹💞
This is the coolest thing I've seen in a long time dude... when the whole world has gone to shit and it's all bad news this made my day.
Cheers
Glad you liked it :)
Hi Maker B,
I just watched your videos on the construction and modification of your 9 cylinder radial engine, so first off may I congratulate you on your workmanship, it is absolutely superlative and I have turned a strange shade of green with envy over your workshop.
I haven’t read all the comments, so forgive me if someone has already brought this up, but I may have a way of increasing the efficiency and power output. In your video you stated that the coils were being energized in numerical order starting with 1 at the top and then proceeding counterclockwise from the camera’s point of view to 2 then 3, 4, 5, 6, 7, 8 & 9 before starting the next cycle.
After you installed the clear crank case cover I noticed that by energizing the solenoids in sequence the amount of movement of the next solenoid’s piston (technically it is solenoid core, but piston sounds better) is fairly small. For example after energizing coil 1 you energize coil 2 which only pulls the piston a short distance and rotates the crank through 40°. However, if you look closely at the position of all the pistons you will find that coil 6’s piston is almost completely out of the coil. Unfortunately, while energizing coil 6 would drastically increase the comparative movement induced of the piston and by inference the crank it is more than 180° (200° to be precise) past the position of coil 1 and would cause the crank to try and rotate in the opposite direction. However, the piston of coil 5 is also almost extended fully and is 160° past coil 1. Therefore by energizing coil 5 instead of 2 it would produce a much greater movement in the piston which would result in the crank rotating through 160° instead of 40°.
If this sequence is extrapolated advancing the coil energization by 120° each step the sequence would be 1, 5, 9, 4, 8, 3, 7, 2, 5 and back to 1 producing 3 rotations of the crank instead of 1. Having said that trying to rotate the crank through 120° per coil energization may be too much so it might work better if only advance the energization order by 80° giving an energizing order of 1, 3, 5, 7, 9, 2, 4, 6, 8 then returning to 1, which serendipitously corresponds to the firing order in actual radial engines.
It shouldn’t be difficult to try as all you would need to do is either rewire wire the coils appropriately or if change the sequence by reprograming the microcontroller.
Great work,
masu
That was my exact thought since radial engines don’’t fire in numberical sequence. Thanks for asking! I’m looking forward to the answer.
Believe me, this guy has the video of highest quality ❤️❤️❤️😍
3:24 "Starting Up"
Age of Z Origins ad: *WARNING*
Actually I got a talabat ad lol
I love how it sounds like an old Biplane starting up... Just love it!
Excellent presentation style! Thank you for putting thought and time in the making of this video for our enjoyment.
Nice one. How do you drive it?
…?
Mate watch the original video?
Love your vids
Yes.
Drive
I'm disappointed the engine didn't drag the table across the room and fly out the window.
The Propeller was mounted in the wrong direction
Tolol
@@benediktfioriolli8165 Is that why it blew over his lego toys behind it, it was going backwards ?
@bill boyd oh... lol
Cause the holder is heavy ,thats the point
That is so cool.
At idle it has the same lopping sound that a real Gas Powered Radial Engine has.
Outstanding! I appreciate the complexity, the precision and the imagination it takes to do this. I also appreciate the care and high quality videography it takes to present it. I do have a couple questions: Where do you get these ideas and do you do this for fun (hobby) or professionally (as in build working prototypes on contract)? PLEASE keep them coming!!
Its cool how the technology used in such a motor is also used to make speakers(coils) and other stuff.
mmm electric magnets, big wow.
Trying to sound smart lmao
before
Its the tech in speakers to make that engine not the other way around
A solenoid
Wow, just seeing the internals and only knowing its electrical pulses I now know exactly how this engine works! Very cool.
I am actually impressed when i saw part 1 but I mostly enjoyed watching part 2
What a fantastic course on metal working techniques with a fun purpose in mind! On top of that, the inner workings of the engine mimic a real radial engine very closely on the principles of operation. Well done, sir!
For an electric engine (something i never thought i would say as an aircraft mechanic)This looks almost kind of practical!
You have a true mast-art rod & counterweight assembly on that crankshaft!
So frigging cool!
Would the induction on those rods heat them up too much to be usefull if this was more life- sized?
Well we have coolant for modern internal combustion engine and oil si why not use it for this as well
Plus they are being cooled by a lot of passing air
@@davidwelner9994 ambitious
@@davidwelner9994 there's no true need for the engine to be completely closed off too, you could have it exposed for more air cooling (though the drawback would be if something were to get lodged in it)
Wauw. Even the starting sounded like a full scale one.
Actually no, the full scale runs with petroleum so ya Mich like a combustion noise.
Yes It does, with that "hit and mis" sound at low revs. Would love to see this on a Remote Control plane(WW2) The Guys at Flitetest would get it flying
I've always wondered how radial engines worked. Now that I can see how. It's awesome. Really makes you appreciate the old aircraft that flew using them
Only, in (some of) the real aircraft, the cylinders (with prop attached to it) are rotating and the shaft is fixed to the fuselage.
Also, the firing order is not sequential in a radial engine. In this 9 cylinder engine, it would be 135792468. It would fire every other cylinder as you went around the engine.
This is 'Beyond' Bad ass. I'm speechless.
I always wondered how radial airplane engines worked. Thank you for the very well presented video.
That feel when your coffee is too hot so you build a plane to cool it off
7:20
When you try to build the LEGO City rescue helicopter to save the man in the river but you made the propellor too strong
H E Y !
hol up
Ryan Park HEY
HEEEEEEEEEEEEEEEEY
what puzzles me - why are putting so many people their thumb down? I guess those are the ones who haven´t got a clue how this motor works nor how much skill it takes to construct and fabricate it. Congrats - excellent work!
That’s the most beautiful electric motor I’ve seen.
Glad you liked it!
I enjoyed every second of this video!! I've seen the model combustion engines in action as a child in the model planes my father build. Love this!
Glad you liked it!!
This happens when the timing of the magnets is faster than the rotor is spinning.
This is absolutely gorgeous. I love to build things. The meticulous detail, and the cleanliness on this is outstanding. Very impressive.
Thank you :-)
Fun stuff. I was particularly fascinated by the way the whole crankcase flexed as this thing ran. Cool hobby you've got yourself there.
Thank you! I have always wanted to know how a radial engine works. Amazing!
This video is also beautifully lit and filmed with great care.
Impeccable work.
Waiting to see pretty big RC airplane with this on it's front
@PunchingMegaTree well, I heard something about traveling electricity by wifi, dont know of its true but it should work on plane big enough
@PunchingMegaTree nope. This can, but not at high RPM. Needs a decent gear bc has a good moment like all electromotors do but struggles to maintain high rpm.
@PunchingMegaTree i suppose a really lightweight plane would work, a sopwith camel for instance
Maybe PeterSripol can help
not sure how efficient the motor is but if that weight together with the battery and radio plus the weight of the plane body , looks like 1800RPM isnt gonna make it.. that rpm is just barely enough to push the plane on the concrete but really isnt powerful enough for the take off run..
Fantastic work man, looks great. I want to see it in a plane so badly.
Good stuff. I went into a bar in Yuma, Arizona earlier this year. On the wall, they had a wooden sculpture. Customers asked what it was and no one that worked there knew. The barmaid asked me if I knew. I did. It was a wooden sculpture of a WWI airplane radial engine. A beautiful thing to behold. Never seen another one like it.
Correction: 8:04 Maximum RPM is shown as 1,808, but the detector is reading the blades hit, which it reads as 2 per each roatation as there are 2 blades for the propellor. So the actual RPM is 904.
May be the detector has a setting, where it auto corrects for this issue, if so let me know @Maker B. Thanks, I really enjoyed watching the video.
The detector works by reflection from the laser back into the optics. It is the same practice that we use to check an airplane's tachometer if it's reading true. No need to divide by two.
When it stops you can see that there's reflective tape on one blade but not the other. Hopefully the laser tach is only registering the reflective tape (ie one count per rev).
@@engineer_cat Yep, that's how they work. Otherwise too much or the IR light gets absorbed into whatever is being measured and it fails to return.
Best thing from TH-cam recommendations so far!
Sry if this was already said, but I think you could move the propeller a bit higher from the table edge so you can get full performance
What a surprise the Shigley!! Magnificent book for mechanical design and widely used in all engineering schools in the world ...Good job
Beautifully machined.
I wouldn’t be able to resist the temptation to fit it to a model Corsair
An electric motor that sounds like a radial gas engine, how awesome is that!!!!!
++
Excellent craftsmanship. I learned today that all radial petrol engines have odd numbered cylinders
Lovely work, both the motor and the video editing. First class.
That thing is ridiculouly awesome. I still want a large one but that would be super expensive
With some neodymium magnets you could make something super powerful, in the range of thousands of watts with windmilling capability.
@@1100101food i think it would be cool sticking out of a 1950s ford pickup...hehe
Would like to hear more about the power source.
I don't often make comments on videos but I must compliment your engineering expertise, fantastic, thank you for sharing..
Thank you very much!
Thank you for sharing, beautiful machine!
A true stunning work of machine art! Can’t imagine what those “thumb-downers” were. thinking...
Those are likes from Australia.
That is an incredible beautiful peace of technology ❤️
Thing is straightforward art piece of mechanical engineering
Thank you!
Well done, sound also cool! World needs more radial solenoid engine! 🙂 Keep them coming!
This is so beautiful! Instant sub!
ONE THING MORE : YOU MUST TO ADD OIL INSIDE THE ENGINE to reduction the friction and sond 🥰👍
Bilal ELFAKROUCHI I think it sounds cool
@@jackjorgensen1440 Nah it sonds cool
@Salman Malik You're right about the sond
*reduce
Sorry I had to
@@rifkifirdaus2199 no
This was really cool! Thank you.
Just absolutely a thing of complete beauty.
Fantastic editing and video quality
Thank you!!!
PS: awesome skills, really liked the Ali cover you did first but cool to see the guts at work, cheers.
Congratulations. Wonderfull job!
Really a great job .WONDERFUL
DUDE!!!!!!! You even got the WASP engine rumble when you spin it over to start up!!!! In the words of Montgomery Burns... EXCCCEEEELLLLEEENNNTTT!!!
I know it's a LOT of work, but the curiosity in me would love to see a double wasp, with a tri or quad blade prop, housed in a gullwing fighter plane model, flying!!! haha Yeah yeah a lot to ask, but hey... if you're going to ask why not ask for it all!!
Any idea how much total construction time you have in this?
Beautiful work and excellent vid work with it!!! Keep it up!
What's next?!?! /evil grin
Excellent it is.
This would be a cool colab with @FlightTest
@@asandberg6 I need to see this happen so much! I wonder if there is a way to change the design to get more power out of it tho, seems a little under powered to me.
Like the F4U? I can't think of many fighter aircraft with two engines, the mosquito is the only one that comes to mind
@@midgetman4206 Do some research genius... Vought F4U Corsair/Engine type

Best coffee cooler ever ☺️🙏
It's gorgeous! I love the sound of solenoid motors. I want one in an electric car or bike.
I just loved it!! Awesome👍👏😊
A few hall-efect sensors, small magnet, some electronics to control the switching...
Very nice project!
Nah, contactors directly on the output shaft!
That is by far the coolest desk fan I've ever seen. I might even copy it!
Gotta love the way the EM fields flex all the coil wires.
What did you drive it with? Please tell me you went old school with a 4017 and 555 and not an arduino!
You got a great engine, I really liked it, I will put a like for your efforts
This is the best ever. Great job. Well done...
Thank you!
Looks like a dancing spider in slow motion 😂
But its pretty cool
What sis you use for lubrication for the internals of the motor... you might have shown in your last video about making it but I don't remember...
Thanks, great videos...
THAT is soooo coool! I love the video!
Nice Job kid! I always enjoy your builds
Great! And "P.S." so funny ))
* sees the domed acrylic front *
Yeaa ... That's gonna be a magnifying effect ... x)
yeaaa.... stfu
That's an amazing concept
Great job! I also need such souvenirs. Thanks for the video, I will try to assemble this model as well. )
Incredible. At some point we could see a vibration mode due to the sampling rate of the camera being nearly exactly a inverse multiple of the frequency of that mode
2:20 When you're an amazing engineer but skipped physics class
I actually kind of want to see it running with that fisheye lens crankcase cover!
@@Liamtronix with some light inside for extra effect!
That, coupled with the use of emojis and text instead of just speaking made this video painful to watch
He's an amazing phycisist! Has no need for engineering class! From ret. Boeing machinist A-3250 Auburn, WA
@@Semparo or RGB light
This is amazing. Great job, also with the tiny 4-stroke engine
Thank you!
That's a very nice rotary engined fan you built there, great work no seriously great work, this is how you take model airplanes to a whole new level.
The whole time i was wondering what the point was of making a noisy electric motor ..Coffee cooler!!!! brilliant
Proposed changes to make it look even better.
1. Change the acrylic's cross section (AT the ends) from square to round, have the bolts be inside.That way you can still look inside and aesthetically looks better.
2. Under the brass cylinders, make a spacer (from whatever thin gauge material you have that's stout enough) that has two holes, enough for you to pass the wires through and neaten the whole aspect.
3. Hollow the stand and make a star shaped receiver for the wires. Pass them though and put the whole engine on a bigger base that allows you to house the electronic bits, switch, pot et cetera.
4. profit.
This is great! Can’t believe there’s not a full scale one in operation out there in your garage to go on a real airplane! Pretty much a zero emissions one! Keep up the great works, wish I had the time to bring my creations to life too! The coffee cool 😎 at the end was a nice touch! Congrats!
Nice man, this looks cool.
덕분에 기계공학과 엔진에 대해 관심이 많아졌습니다 ^ㅁ^
I think the term ridiculously awesome very proper for this toy, a term from one of the comments!
Now to see it in a flying RC plane. :)
Awesome motor.
you are a madman....... i couldnt resist making a plane if i had this lol
Thats pretty cool on the RPM did you divide it by 2 to account for the tach reading both sides of the prop?
It was pointing into one side
Hey. This is an excellent work. What kind of driver do u use? How many volts and amps per solenoid in 1800 rpm?
top secret please!!!!!!!!!!
I started imagining writing code to run on a microcontroller the drive it, but that's just because I'm a software engineer, not an electrical engineer. LOL. It's probably something similar to a DC to 3-phase motor driver. But... 9 phase?
@@yarnosh Yeah i think so. Actually it doesn't have to be all electrical. He might have used hall effect sensors or something like that.
He don't wanna share it probably, jerk xD
@@yarnosh Technically, these aren't 9 phases, but 9 different solenoids.
I think the control is just sequential in this demo, as I don't see any additional feedback sensor, but he also might use one of the selonoids to trigger the sequency, which implies some advanced knowlage in MCU programming and electronics.
Would be nice to see how this comports as generator.
50 years ago I made one of those as a project in 8th grade electricity class. Much cruder of course, and only one cylinder. (Modeled more like my store-bought steam engine that burned pellets under a boiler.) Wound the solenoid by hand. Crank shaft was a bent piece of clothes hanger. Flywheel was a steel coffee can lid. A cam on the shaft pushed copper strips together firing the solenoid from a big square 6 volt Ray-o-vac lantern battery. Nobody had ever seen anything like it. Maybe 600 rpm, way too fast to count. Wow, these videos brought that memory back, and the challenge of cobbling that thing together from garage scraps.
Very nice work and craftsmanship
ㅋㅋㅋㅋ커피 식히는 용도 였군요~ 너무 아름다운 엔진이네요 감탄하고 갑니다
