It's like a steam engine, except instead of steam pressure it uses electromagnetic force. The switch acts like the steam valve, opening and closing as the crankshaft rotates. You could control the timing of it by sliding the switch forward or backward, or by changing the shape of the cam. The switch is noisy and will wear out, but for a demonstrator that only runs for a few minutes once in a while to show off to people it's very cool and keeps it simple and mechanical with no electronics needed.
I'm thinking the same thing. I'm not really an electrical motor hobbyist but I'm interested in it. I'm wondering what could be used instead of this switch to do the same task like maybe a magnetic switch or sensor similar to a crank trigger on an automobile crankshaft dampener?
You could construct a more robust momentary contact switch to replace that relatively fragile microswitch. I think you should use a little graphite lubricant inside the bore of the solenoid to further reduce friction. Still, very good work.
First person I've seen since Highschool using Siemens Solid Edge. I loved using that program and could always make some pretty cool stuff with CNC and 3D printers! Glad to see someone putting its advanced amount of tools to use!
demonsparkx make something that amazed me that our problem ,that problem this is basic or toys don't worry. log your own made ,how good you are thanks,,,
this idea could have so many applications. In a production line a really bored worker would be responsible for making one of the parts. When you have the ability to make all parts and bring them to work together it becomes an interesting project.
Very interesting concept. I have a suggestion, though. I think that switch won't last too ling. You could instead use solid stated components, like an IR switch and transistors instead of that mechanical switch. Less moving parts, less wear.
+Robert Kattner the inductive current might at switch break is likely to damage the contacts in short order. At the very least, put a diode across the coil to limit contact arcing. the micro switch position should have been made adjustable to peak the torque.
Watching you work is like watching early inventors experimenting and discovering. How early in life did your tinkering start? Who was your mentor, your hero? How long did it take you to outfit your shop? It's just fun to watch you create from raw material! It would be wonderful if parents realized what you are demonstrating on RU-vid should be part of all children's curiclum.
Excellent work. You really need to add a 3d printer to your tools mate. That would outclass the woodwork and non metal part machining by the factor "a lot" 😜
The switch will break pretty fast because of the relatively high voltage of 30v DC and the inductance of the coil there will be high voltage sparks of about 2kV in the swich. Try a small thyristor from old high power electronics or buy for 1€
@@karimadel5911 Actually the pistons in a two stroke single piston motor are push only so the solenoid doesn't need to push and pull. The momentum in the flywheel allows the solenoid to reset while the power is off.
Wow 😮!! all those tools!!!!.... mmh! That is where the young boys and girls should be working with all sciences, and learning. It is a great privilege to have a room full of all tools electrical, mechanical, and other more... Excellent... thanks for sharing. 🚀
Never use gloves on rotary machines such as that sanding belt... If a piece got caught in the space between the belt and the wheel, you'd break your wrist, likely at the least with worse injuries resulting...
Nice wor,well thought out. I agree the switch will let it down in time, may be better with a read switch, It will go forever then, lol well done worth watching a craftsman at work
So what exactly is the output of this engine? You said you used 30V of DC current what would be the output of this? And what would you suggest it could power? Such as a toaster?
the solenoid generates a magnetic field that pulls the metal. I think it pulls every time the piston is away from the solenoid and stops pulling when it is inside it (hence the asymmetrical wheel for the switch)
MattyE It uses the skill of the coil. if you get some voltage on it, it will inhale the core to the coil. for getting it back it uses the contact switch there i guess. it will disable the power supply to the coil and the core jumps out from the coil
