muy bonito.

[Ketkaiball]

Very beauty design. Receive my congratulations for a very good work!!!

[rayunseitig]

nice.

this is great!

There is a german chap running a 3 cylinder DKW motor flywheel with this principle. I have a single version underway as well. Not enough torque for a vehicle but dyno power is impressive off a 4lb flywheel on roller bearing cranks.

Incredible build quality, you must be a machinist. Did you find plans online for this?

[BlakeMason2]

Really interesting. You should post plans (yeah I'd buy them.)

[budsiskos]

what switch did you use and where did you get it?

[cffellows]

I used a microswitch.  Bought a bundle of them on eBay.

[fdoca]

Buautiful motor !

Does it consummed much current? in milliamp?

Can it be a powerful engine? Thanks

[cffellows]

It doesn't require much current, maybe an amp at 18v. It's no very powerful.

Nice work!

I have never made my own solenoid, did you wind the wire on a metal sleve or is the piston riding in a plastic or pvc sleve?

[cffellows]

The wire was wound on a plastic spool that I turned on a lathe. The center of the spool was drilled out for the plunger.

You ever think of using a magneto on the fly wheel to create the electricity to operate the the solenoid? I know that the same set up on a lawn mower creates like 20,000 volts for the spark plug, but I don't know how many amps that creates? Also it could be timed to only fire the solenoid when the piston is at it's TDC or a little past instead of the flywheel working against the solenoid. If it worked you could use a dimmer switch as a speed controller, between the magneto and the motor.

[mascobe]

Nice one! I am working on one of these with a mechanical speed control that varies the dwell of the switch which in turn changes the amount of on time in relation to the depth of penetration of the plunger. Too many ideas and I'm at a place in my life where time is a big issue so it may be a while before I can post a video of the finished motor.

[CraziestOzzy]

besides heat gain from those amps, is there issue with friction in the barrel where the "piston" sits?

[cffellows]

No. The piston is a pretty loose sliding fit inside the solenoid.

[jamesroney]

Now how about getting that to run without the aid of electricity.

[getjoenow]

does it have more or less torque than an "old fashion" motor? And what about the power use, is it better or worst?

[cffellows]

Less. These types of engines are not at all efficient. This motor is running on 12 volts and pulling close to 3 amps.

[budsiskos]

yah but its much cooler than a normal dc motor.

Elecrtonic steam engine :)

nice craftmanship! sweet!

[radicalnegative1]

Wow. That is truly amazing. Great job!
