Matthias, you are very versatile, I am a professional of electricity and I really like wood, metal, stone, etc and everything related to craftsmanship, I am very happy every time I watch your videos, especially the quality of the image, the realization of the video and the cleaning of the environment in which you record. Thanks and waiting for the next one.
My Father has a box full of projects like this from High school.They were intriguing as a boy.His were all hand wound magnets of different function.I was the only ten year old who knew how an electric motor worked.
Matthias. Lots of comments so you may not see this one. Excellent build!!! Would be fun to see and old flat leather belt running from the flywheel to something that needs spinning? Perhaps a miniature saw mill blade?
+Matthias Wandel Not to really cut wood (tiny logs). Just a display or model. Well, if it didn't really cut wood, you probably wouldn't want to build it - haha. Plus it would probably remind you of all the work you had to do at your Fathers sawmill.
Got some solenoids from one old multifunctional printer. Now I know what to do with them. Thank you. Now I need to find some use for all the stepper motors. :D
Cool! I build one of these with a big solenoid from a copy machine and Meccano (Erector). After touching the "distributer wheel" once and felt pain I also installed a diode.
I loved this, thank you. I must make the wooden air enging I got plans for if I can find them after 3 computer changes. They are spread all over an external hard drive so it'll be a bit of a detective story. Best Wishes, Brendan.
Interrupting that coil like that must produce an unholy amount of back emf. A flyback diode might be a good idea. Great engine though, it's hypnotic like a steam engine.
A diode with a resistor in series (or a zener diode with a normal diode) will still collapse the magnetic field fast, yet they will reduce the back EMF to a predictable reasonable level. It will still dissipate the energy though. A little more complex circuit would be required to regenerate the energy.
Thanks, I found an old solenoid in a parking lot, and it's been collecting dust and I haven't found anything to do with it. Might make for a fun project.
Make a train and power it with the flywheel :) that would be an interesting series, making the track and points for your homemade locomotive. Great vid btw
Very nice work! I'm curious how long you are able to run this continuously? In my experience typical solenoids have overheating issues when they are rapid cycled like this.
The only real power losses on this engine except the obvious mechanical and resistive losses on the coil are induced currents in the rod and loss of magnetic energy when the switch opens. The first can be eliminated by using a ferrite rod instead of a metal rod and the second if you use a small electronic circuit to redirect the magnetic energy to the source (or store it to a capacitor until the next cycle). Resistive losses can be reduced by carefully timing the on and off time of the coil to have it active only the time that it does the most work. Mechanical losses can be reduced by using bearings. After all that the final motor will actually be very energy efficient.
Was the flywheel made out of European Buckthorn, by any chance? The size, colour and grain (and characteristic tear-out visible at 4:15) look a lot like it. The fact that it's also readily available (i.e., free) throughout southern Ontario also appeals to your thriftiness, I'm sure.
From what I've read so far, I guess it stores kinetic/rotational energy by basically getting a big heavy wheel to rotate. Now imagine turning the engine off, the flywheel will continue to spin for a while, so it has a lot of stored energy. And I guess when running normally, that energy is also continuously used. Interesting!
Main purpose is to keep the thing moving after the solenoid turns off. When that happens there is no force on the cam but the solenoid must be pushed back in before it can fire again. In order to do that the heavy flywheel is there to keep the shaft turning so that it comes around for a new cycle. Pretty similar to why internal combustion engines use flywheels. The flywheel there stores the energy produced by the power stoke where the explosion happens and gives off the energy in the next cycle to compress the air mixture again so that it can be fired again.
Is there any way to add in something that works like a throttle? That's a really cool project, I guess you could turn it into a replica steam engine with a few more parts.
So, a solenoid is a eletromagnet that pulls the metal rod, with a alternate current, to make movement. But if ou have something like a v16(solenoids) with somekind of intercalated system where 6 push, 6 pull (repell) the rods (these repelled ones could be eletromagnets too, to streghten the repulsion) makin it get high torque and high speed and reliability in control. if one hobbist wanted make it own v16 eletric replica or RC it maybe could. I dont do it because i learned all of this online and dont have the skills to try, but love it tho. Graphen, activated carbon, aliminium air or magnesium diy batteries are cool too, where are all the all diy eletric car topics on the internet?
Now this just needs a microcontroller and a power transistor as a governor. Then just crank the power supply up and if the time between switch closings increases: increase the transistor duty cycle, if the time between closings decreases: decrease duty cycle.
Neither a 555 will do. This device needs to be timed by its rotation and the coil needs to be fired at the appropriate point of the cycle and stopped accordingly.
Hi Matthias, Have you thought of building plans for a "tiny house". FYI, I think your combination of skills and practical minded point of view would make for a solid solution for many of us in the USA who are looking for a nice little home. Thank you for the channel--and best regards! Wil Machinist and longtime subscriber
Mr. Wandel, what characteristics make this type of electric motor not practical vs other types? I suspect it has to do with the limited contact time, meaning the motor is "coasting" much of the time. Am I tracking your line of thinking?
Please make a video of one of these motors but with 6 cilinders. But try to make it easy, just put each solenoid side by side (not like in a real car motor)
i bet you could make the piano that feeds the chicken when it plays it, that I saw on old movie/film I watched w/my gpa (you could probably make/tweek that ^ Awesome engine to be automatic feeder).?
Why the holes on the flywheel? I always thought that crossings were made in casted flywheels to increase the moment of inertia without added material, but if the material is already there, wouldn't it be better to leave it? The more mass, the better.
nightcoremixer1 Thank you. Well, if they're not into '70s music and they're addicted to the LATEST&NEWEST, last year Ciara made a nice cover of "Paint It, Black".
PaxGrime | Viper Boosting I was referring to the physical representation of functionality not the materials used to create it. I was purely stating that this could be a substitute for using a steam based motor for aesthetic purposes.
I've always loved solenoid motors :D! I've been meaning to build one for ages now from parts of an old harddrive, plus I have some hall sensors from an even older VCR :P
You should teach. Kids would love the way you explain stuff.
If I did that, I wouldn't have time to make videos, and you would have nothing to watch.
Matthias Wandel
You could just film the lessons. Make a neat TV show out of it, and have volunteers or staff edit the episodes down for youtube videos
Bob Y how to use a solenoid on a pocket hole jig
My 6 year old’s favorite channel ever since he was 3.
The most impressive thing about this video is saying "pull this e-clip off without losing it" and then you didn't lose it!!
I was waiting for that to fall across the room
e clip = jesus clip when it shoots of "jesus f#*k crist
Fun fact: the "e" stands for "escape."
the evil clip from e corp
My dad always called them that because he said when the flew off you looked upwards and asked "Jesus, where did it go?"
Matthias, you are very versatile, I am a professional of electricity and I really like wood, metal, stone, etc and everything related to craftsmanship, I am very happy every time I watch your videos, especially the quality of the image, the realization of the video and the cleaning of the environment in which you record.

I really like when Matthias does electrical projects, I hope he does more in the future!

The engine isn't nearly powerful enough for that

You always manage to create something that blows my mind, thanks Matthias.
If DiResta talked and explained what he was doing in his videos... this is what it would look like. Great video!
"on the next episode, i'll be turning this into a table saw."
might have enough power for a light duty scroll saw
to cut paper, maybe
It's like 0.0001 HP
Never said it would be a big tablesaw.
Mr. Wendel sir, I also like that you did not add a reed switch. pierre
I love your projects you are so good at coming up with a way to make everything by hand so simply. I love it

Cool! I build one of these with a big solenoid from a copy machine and Meccano (Erector). After touching the "distributer wheel" once and felt pain I also installed a diode.
Maybe for your next project you could make a reciprocating saw. That's something I've never seen among your collection of machines and tools.
Nice demo of linear motion to cylindrical. Thanks Matthias.
Ficou perfeito este motor solenoide. Parabéns! Rio de Janeiro RJ Brasil
I loved this, thank you. I must make the wooden air enging I got plans for if I can find them after 3 computer changes. They are spread all over an external hard drive so it'll be a bit of a detective story.
Best Wishes, Brendan.
Dude, you should be working for the Canadian Space Agency. Brilliant!
I really like the lignum vitae bearings. Classic!
Interrupting that coil like that must produce an unholy amount of back emf. A flyback diode might be a good idea. Great engine though, it's hypnotic like a steam engine.
A flyback diode would delay the collapse of the magnetic field, which would slow it down. So far, no issues with the contacts.
If it was causing an arc across the contacts, then some form of snubber would help, but as for now, if it ain't broke, don't fix it. 👱🏻
A diode with a resistor in series (or a zener diode with a normal diode) will still collapse the magnetic field fast, yet they will reduce the back EMF to a predictable reasonable level. It will still dissipate the energy though. A little more complex circuit would be required to regenerate the energy.
So satisfying to watch, well done
Awesome build and a good explanation as well. Thank you!
Thanks, I found an old solenoid in a parking lot, and it's been collecting dust and I haven't found anything to do with it. Might make for a fun project.
This would be awesome to incorporate into another toy loader project. Some type of electro-mechanical simulated steam excavator or something.
Problem is, it's not very powerful, so not the best to power stuff with.
It still fascinates me how in Canada every screw is a Robertson.
Lovely little project. Triple-like!
Make a train and power it with the flywheel :) that would be an interesting series, making the track and points for your homemade locomotive. Great vid btw
Very nice work! I'm curious how long you are able to run this continuously? In my experience typical solenoids have overheating issues when they are rapid cycled like this.
I ran it for about 10 minutes. Average current at 12 volts is 100 miliamperes. Its a very efficient solenoid, so it only gets warm
The only real power losses on this engine except the obvious mechanical and resistive losses on the coil are induced currents in the rod and loss of magnetic energy when the switch opens. The first can be eliminated by
using a ferrite rod instead of a metal rod and the second if you use a small electronic circuit to redirect the magnetic energy to the source (or store it to a capacitor until the next cycle).

i luv this been wanting to make one for a little wile now
You should make a large windmill.
Very nice. Would be great on a train model.
Muito interessante!!! Engenharia Mecânica!!! Shalom Adonai.
I recon this could be amazeballs to sharpen pencil leads, not the whole pencil, just the lead.
One of my favorite quick videos you've done, Matthias. What is a flywheel for, specifically? To balance it and keep it stable?
I think it's to give it momentum... but I could be completely wrong!
From what I've read so far, I guess it stores kinetic/rotational energy by basically getting a big heavy wheel to rotate. Now imagine turning the engine off, the flywheel will continue to spin for a while, so it has a lot of stored energy. And I guess when running normally, that energy is also continuously used. Interesting!
Also for the point when the contact is open to spin the whole thing through a cycle until the contact closes again.
Main purpose is to keep the thing moving after the solenoid turns off. When that happens there is no force on the cam but the solenoid must be pushed back in before it can fire again. In order to do that the heavy flywheel is there to keep the shaft turning so that it comes around for a new cycle.
Pretty similar to why internal combustion engines use flywheels. The flywheel there stores the energy produced by the power stoke where the explosion happens and gives off the energy in the next cycle to compress the air mixture again so that it can be fired again.
It's for inertia, without the flywheel it wouldn't turn constantly.
Hello Matthias-
Great little motor you have there. The simplicity is wonderful. What is the solenoid out of may I ask?
Great stuff. I suspect you were one of Father Christmas's gnomes in a former life.
Now make a miniature belt driven saw mill. ;-)
Two stroke electric engine. Brilliant!
That is just cool! LOL. Loved watching this one.
Any idea what device that solenoid was originally scavenged from? Awesome video!
Nice work!
I always wanted to build one of these, but I couldn't find/build a suitable solenoid...
Is there any way to add in something that works like a throttle? That's a really cool project, I guess you could turn it into a replica steam engine with a few more parts.
funnyest nice little motor now i want to build one myself and optimize it Thia should be like competition who can make it rev the most
Just add a small propeller to the crank and then you have a portable hand fan for hot days
Don't coils in mechanical solenoids get pretty hot? Could you use a fan on/as the flywheel to cool the solenoid if this is the case?
this one barely gets warm. Averare current is 100 milliamperes
Not near enough wood working in this project. Are you changing your focus?
So, a solenoid is a eletromagnet that pulls the metal rod, with a alternate current, to make movement.

You do not realy need an MCU
nope just a 555 timer and some other bits.
Neither a 555 will do. This device needs to be timed by its rotation and the coil needs to be fired at the appropriate point of the cycle and stopped accordingly.
You should make a stirling engine
That's some pretty thick coat hanger wire.
NOS. They don't make 'em like they used to. Or, maybe in Canada, they STILL make 'em like they used to. Hmm ...
Ohhh... I see...
This is the prototype for your homemade reciprocating saw powered car... ;)
:) instead of carving the base for the wheel, it was easier to displace the wheel out of the base board ;)
Am I the only one that thinks that this was filmed a long time ago?
Something is different. Now sure what. A new camera?
New style, maybe? Different editing? The outro is new... :)
Be careful bending that coat hanger, the ATF will be all over your house in a few minutes
Sehr gutes Video. Grüße aus der Heimat
Halfway though the video I saw wood and was like " hey! I know what that stuff is"
immer wieder schöne Videos
u should like lathe that flywheel, so thats its a "circle", would make it look nicer i reckon.
maybe not practical, but still a really cool project!
just curious why did you drill holes in the flywheel
Now you just need to make it into a reciprocating saw.

Is it too weak to use it for some sort of marble machine?
Hey Matthias, where do you get your exotic hardwoods?
Why was the copper used again? why is closing the circuit needed?
Mr. Wandel, what characteristics make this type of electric motor not practical vs other types? I suspect it has to do with the limited contact time, meaning the motor is "coasting" much of the time. Am I tracking your line of thinking?
I believe it's because the duty cycle (the amount of time it's actually doing work) is horrible.
Awesome work :)
How many rpm do you think the flywheel gets?
Now all theres left to do is building a bandsaw powered by this :D Lovely coil by the way. Where would you get one?
How much power did you get with what consumption?
That was neat and fun
Please make a video of one of these motors but with 6 cilinders. But try to make it easy, just put each solenoid side by side (not like in a real car motor)
Now put some wings on it, and turn it into a generator :D
could you make some sort of electronic pencil sharpener using this?
Awesome!
i bet you could make the piano that feeds the chicken when it plays it, that I saw on old movie/film I watched w/my gpa (you could probably make/tweek that ^ Awesome engine to be automatic feeder).?

how do i make a solenoid (with which wire) and what is the Volt u are passing through
Beautiful
where did you buy that solenoid

Why the holes on the flywheel? I always thought that crossings were made in casted flywheels to increase the moment of inertia without added material, but if the material is already there, wouldn't it be better to leave it? The more mass, the better.
Probably for aesthetic reasons.
Moment of Inertia is better per unit weight that way. (Short form, Mass further from the axis is worth more momentum than mass closer)
I LIKE

Now it's just a matter of waiting for the trolls to let out some steam, and the project is finished!
have it turn a generator and power itself!
