More information:
A solenoid engine uses the magnetic pull of solenoids to turn a crankshaft. The crankshaft on this engine was built from an old rotary motor shaft plus various m4 nuts and bolts, and is counterweighted to balance the rotational and reciprocating mass. This engine does not develop much torque, certainly much less torque than a standard rotary electric motor can produce, for the equivalent power input - for this reason the solenoid engine is just a novelty and an educational model.
I built this engine for fun, from mainly scrap metal and wood, and using mostly hand tools, and a basic drill press, during the summer of 2014.

Thanks for watching.
i like how the speed adjuster is completely mechanic i know it took a lot of time to calculate and build
Great job,best one ive seen yet.
All the best from OZ.
Thanks for your comment. Regards from UK.
Sounds like it can be put in a Vespa, this is so awesome, love from ZA
Under full load it sounds like a lawn mower starting... love it
Great Work!
Can you please upload a tutorial video for this?
I like the mechanism you use to change speed
I like the parallel motion link on the wiper!
Thanks - I didn't know that mechanism would have a name! I made it out of a wire coat hanger and some brass tubing, it's a bit more proper than relying on a wire bending as it was before ;)
Try googling "Watt's parallel motion". Oh and for more fun mechanisms there's always www.animatedengines.com/
Thanks for that and thanks for the link - I shall investigate ;)
BEAUTIFULLY BUILT!
Love it, would be awesome if you built a PWM controller for it. Kinda like going from a carb to fi..
Imagine a big flywheel on it
Hi David,
I love your work! Prior to seeing this, I only ever used electronic PWM's that i built...This is truly brilliant and i really appreciate the work you have put in to the aesthetics too! I understand the workings of this, however, I would love to know what you used to coat the copper to create the barrel of your PWM?
Regards, Riley Otton
Hi, the pwm barrel is made from copper water pipe and electrical tape. Thanks for commenting.
would you show a tutorial on how to build a simple single cylinder engine like this one? id love to build this!
I might do it one day ;)
what factors limit the practical output power of these "engines"? In other words: How are these "engines" fundamentally different from the way conventional electric motors function? Great video!
They use a coil to move a thingy that turns a crank, and motors use a coil to turn a thingy without a crank.
Nice design and craftsmanship, It is a motor not a engine.
Hey thanks. The motor / engine thing is debatable, but the Oxford English Dictionary defines the word "engine" as "A machine with moving parts that converts power into motion:"
You got me.
Beautiful peace of machinery !!! I really like how much effort you put in to mechanical, wiper, like commutator. Don't even wont to think about how much time it took you to make a V12. My question would be, how much more rpms can you achieve on, say v12, if you will upgrade it to, say rotary optical encoder? Its just a disk on crankshaft, with holes for optical sensors, which in turn will drive your NPN transistor. And instead BJTs maybe Mosfets would do better, they operate faster,have lower voltage drop, you would only need to add free-wheeling diod's. Would love to build one in future, but now I'm on my electric project. see videos :)
Yuri LM Sorry just noticed, you have flyback diod already :)
Nice solenoid
Really Great little engine!
Dude, this is definitely cool!!! Really great, But how did you do the speed control mechanism?
Thank you very much
they should make an electric car with that motor :D
great workmanship, well done. am going to try this myself and was considering using reed switches as I assume it would be less resistance. you must have thought about that, and I would be interested to know your thoughts.
thanks for posting your video's
I thought about using reed switches, but found it would be difficult to alter the duty cycle as compared to this mechanical setup. Thanks for your comment.
hey, just wanted to comment that I really liked your videos, but I have one question: how was the rotary switch made? it seems to be a copper pipe with sections masked, but how, also, could you maybe do a build video, where you take apart and explain the making of the parts? thanks!
I'm gonna make a huge one for a go kart
0:58 is it true thet you live next to the football stadium?
Yes...yes... yes yes yes... yes yes yes yes... yes yes...))
It's awsome it sounds just like a single cylinder diesel! Love the t03 transistor, why not a mosfet?
I just used what I had in my spares box. Thanks for commenting.
Very nice
great build! regarding the speed controller, how many degrees of the entire circle are exposed material? also at the slowest speed, is the current applied to the solenoid when it is fully extended? or maybe even slightly after it reaches its full extension? thankyou
Thanks! At full throttle there is approx. 180 degrees of bare copper exposed on the speed controller. At the slowest speed the solenoid switches on briefly approx. half way through the piston's travel.
What is the price for the this?
Congratulations, great idea !!
Do you have the link to buy this solenoid?? I did not find on ebay.
And what is it and why that 1k ohm resistor that appears in the map? Do you have the link that i can buy this resistor too?
Thanks!!
Tesla needs to see this
Could you tell me the construction and materials needed? I am a student of automotive engineering..Thank you.
Great! I would like to see how much RPM it can have without commutator.
hi! I am going to do this as my project in engineering,would you please help me how to make it and what components are required and where they are available.Execting soon reply
i like your work,for your next big project try making a w16 Bugatti solenoid engine
Um motor deste tipo consome muita energia? Ele gera muita força, quer dizer consegue deslocar alguma massa?
If you reworked the blue insulation on the switch rotor, you should be able to make it run in reverse too...................??
Well spotted - yes it does run in reverse - there is a small strip of bare copper on the outer edge of the blue insulation for this purpose.
Are there any practical uses for something like this or is it for play?
No it's just for play.
é só fazer um carro, caminhão ou trator com esses tipos de motor. ia ficar muito legal!
Would a solenoid with a shorter stroke perform better? Ideally you could get a faster cycle, but timing cold become tougher.
Is 50Hz a limit on how fast this can run?
Shorter stroke = less torque but more speed. I take it you mean 50Hz on the piston, or 3000rpm? If so, no, I have had this engine up to nearly 4000 rpm so far. Thanks for your comment.
+davidrobert2007
Thank you for the clarification
This things are very interesting, I really need to build one of these, I already have a few solenoids lying around...
Why not eliminate the switches and go full optical?
Where did you get your l brackets? I've looked all over and can't find similar ones
I just cut them from aluminium angle (available on ebay) and drilled the mounting holes. Aluminium is very soft and easy to cut and drill. I hope this helps.
is that more efficient than it's original design?
What do you use for a power source because my solenoid motor is a pig and wont work on normal sorces
This engine normally runs on an apple mac power supply, which is 24v dc and about 3a max. You may need either less friction, or more voltage, in your engine, maybe both. I hope this helps.
What's the purpose of the diode? Wouldn't the current just go back to positive through the solenoid no problem?
The diode in this application is called a flyback / freewheel diode, it's purpose is to allow the back emf (high voltage spike caused by the collapse of the magnetic field in the solenoid coil when it is disconnected from the circuit) to dissipate through the resistance of the solenoid coil. Without this diode the back emf would destroy the 2n3055 transistor pretty quickly.
Oh okay I get it. And the copper wire, I see that it rides the wheel, but where is the electrical path going? It makes sense on paper, but I'm trying to see it on the machine itself.
The copper wire that rides the wheel goes to the base of the transistor (via a series resistor) and the transistor (being used as a switch here) switches the solenoid coil on. This arrangement allows the rotary speed control switch to use a very low voltage to avoid sparking and burning of the moving contacts.
Hi, could you give me the layout to connect the solenoid the transitor and the batery. thanks in advance.
wow, what is the transistor for? I thought the copper strips already control the pulse?
I used the transistor to keep the solenoid current away from the rotating switch contacts. The rotating switch will spark and burn the contacts with the higher solenoid current going through it.
ah i see. thank you for your prompt reply! cheers.
So the speed control works with a copper pipe, that has a bolt/nut on its end, another wire on that, and insulation tape like so, that theres only a "triangle" of the copper am i right?
You are correct.
which material did you used for the piston?
neodymium magnet?
The piston is made of steel.
você pode me explicar o porque da mudança de velocidade ?
Why not a carbon brush instead of and copper wire?
great job anywway
Copper wire rides the step / edge of the electrical tape better.
hi david. how much or many newton has the solenoid?
The specification is not given on the suppliers website, but here it is anyway www.esr.co.uk/electronics/switches-solenoid.htm
como funciona o regulador de velocidade? o que é aquilo ? e porque aumenta a velocidade? alguem por favor me responde !!!
Very interesting and beautifully made! I'd be interested to know how you control the speed of the push/pull action of the solenoid, is it like a pulse of electricity that increases in frequency? Thanks!
Hey thanks! the solenoid will only pull but not push, and it is switched on when the movable wire contacts the bare copper section of the rotary switch / commutator. When the movable wire contacts the insulated section of the commutator the solenoid switches off and the flywheel momentum turns the crankshaft, pulling the piston out for the next power stroke. I hope that helps!
davidrobert2007 That is a very clever way of doing it, similar as to how the windings of a motor receive power from the brushes as the commutator rotates right? Was this a scratch build or could you get kits to do something similar, looks really interesting but I don't think I could do the metal work myself!Thanks!
Yes it is very similar to how motor windings receive power, and yes this was a scratch build. The metal work was very straightforward on this engine as it is all aluminium, therefore it is easy to cut, drill and form using basic hand tools - you should give it a try!
Can you sell me ? I really love the sound I need this in my office 👏🏻
awesome!
Could you please send me the link to the speed control
ЦукО опять провод!:))
I plan on building one of these myself but and have a spare laptop power lead but I'm unsure how to get the positive and negative from the single lead, could you please explain how you did this? :)
First, cut the laptop end plug off, seperate the two wires, then use a voltmeter to measure the output voltage, if the polarity (+ -) is reversed then the voltmeter will read minus voltage. I hope this helps and have fun building ;)
davidrobert2007 Awesome. Thanks for the quick reply also. :)
davidrobert2007 Do you think the laptop power supply could power your V8 design? Sorry for so many questions but I'm an electronics idiot so I have no clue. :P
The trouble is that laptop power supplies come in many different power ratings - here is a link to a video by Martin Lorton where he explains dc electrical principles about current, voltage and power ruclips.net/video/F_5sV8s9ZEA/видео.html - it's a bit lengthy BUT, definitely worth watching to help understand the basics. I hope this helps.
how the speed governor ? what is that ? and because it increases the speed ? someone please answer me !!!
The speed governor moves to adjust the duration of electrical contact between the rotating copper triangle and the yellow wire, when there is electrical contact the solenoid is switched on, and pulls the crankshaft round.
Hello dear engineer, I like your electric motor very much, please help me to make one too. I forgot to tell you about my job. I am a primary school teacher. Your attention, engineer, means you, dear and noble friend🌟🌟👏👏👍🌹
can you please explain how the speed control works?
When the yellow wire moves onto a wider part of the rotating bare copper triangle, the solenoid receives a longer power pulse, and vice versa. It is mechanical PWM, or pulse width modulation. I hope this helps explain it.
hello
as the speed control work ?
thanks
I love this electro mechanical devise! do you think using a laminate piston of high carbon steel would reduce magnetic lag and make a difference in speed and or power? I wonder how much more power your v12 model has than this one. I am big into apposed engine types used in aviation such as the 0-290 like what's in an old porch or VW Bug. I also like the balance of these engines naturally balancing themselves out firing in complete opposite ways at the same time. I've been seeing stuff on super electromagnets as well using paper thin sheets of cooper and insulator stacked up in a way creating crazy amounts of lines of flux and all that. I wonder can this concept be used with your circuit solenoid engine. do you imply the joule thief circuit in your circuit? I know a lot more about gas engines than I do electric but I was looking at your diagram and wondering if that transistor your using was making your circuit like a joule thief circuit or school girl circuit what have you? I don't want to sound crazy I've just got a lot of ideas from what your doing. I feel like this electro mechanical cam shaft you made is brilliant, and I want to know if you think this engine can be made to pull more than it needs.
Hello friend how are you, I am a boy who is developing a model similar to one of your works but I am in the process of researching the cost and benefit of the project, and have an analysis of efficiency in economic savings with this engine model, in which it implies durability potential, its maintenance management among others...so please support me with some data, mathematical calculations
lo malo es que hay roce para la propulsion eso es igual a desgaste
did you buy the solenoid or build it?
I bought the solenoid - available here www.esr.co.uk/electronics/switches-solenoid.htm
thanks!
shouldn't you add a second cylinder that gives opposite voltage so it pulls back too
A nice idea in theory but opposite voltage has no effect on the direction of solenoid pull, it can only pull and cannot push.
ok so it's not a magnet inside but just aluminum or any metal really
I thought opposite magnetic field would pull or something.
I wonder what the efficiency of this type of motors is.
still cool.
It makes sense that the solenoid would reverse it's action with reverse polarity, I don't understand it myself to be honest, maybe someone here could help explain it. In any case the solenoid engine is not very efficient at all when compared to a standard dc motor. Thanks for commenting.
i think it might work similar to a solenoid gun using eddy current and such
just able to repeal
Hope we'll see those motors in cars :D
davidrobert2007 is a heavy spring a possibility? the one i have is not encased as urs and u can clearly see a heavy spring to pull it back... i enderstand that reversing it wont pull it so i just stopped my curiosity at the spring
Why not use optical switching
+Rich Gordon I prefer analogue
soo cool
I speak the name of the solenoid to see if I can buy here
solenoid model is SOLEN 121E16530 www.esr.co.uk/electronics/switches-solenoid.htm hope this helps
thanks
How much would something like that cost?
If you build it yourself it costs very little money, but quite a bit of time.
how many volts and amps is it
24volts and 400mA max = 9.6 watts maximum.
I really want to build one myself but I cant get any information about it at all. Can somebody please help?
I just cant figure out where I can get the parts for the crankshaft, flywheel and PWM-wheel from.
A lot of the build process involves finding random "odds and ends" and cutting / bending things to fit - there is no set process, but what I did was to get ideas from other people's engine builds, plus a ton of research on google. For instance the crankshaft on this engine was the armature out of an old electric motor (maybe from a fridge - not sure as my friend donated it to me), the pwm wheel is made out of an aluminium airline fitting (cut down) with a bit of copper water pipe pressed onto it, and electrical tape to insulate part of the copper area. There is a lot of "Heath Robinson" type engineering involved, I recommend to start small and work your way up, and good luck.
you can find the flywheel in devices which use audio or video or data tapes (70/80-90ties electronics)
there's a few good tutorials on yt, you know. do a little research. visit your local hardware store. look at copper plumbing fittings for use in rotary switch. almost anything, balanced, with a center hole can be used as flywheel. steel or heavy copper wire is used for crankshaft.
What are things used for it.
It has no real practical use.
Класс вот бы такой большой и в жигули и на мопед
which is better upon delivering loads, solenoid engine or electric motor?
how on earth do you start it up
By spinning the flywheel by hand.
oh okay
Hey hiw to work it
how to make this ?
how much torque?
Very little when compared to a traditional motor using the same power.
