A simple solenoid engine (Motor)

 

Built from old bits of junk laying around.

 

 

Since I did the video, I've managed to get 1100 RPM out of it. Now I have to see what kind of work I can make it do.

Neato, I see a fan for the summer shows at least.

It is cool, but i dont understand the solenoid part of it yet. I guess i would have to see the solenoid side not moving to understand the mechanics of it better.

the solenoid acts the same way as a piston in a gas engine.

That pretty neat. Looks like you have a pretty large solenoid on there.

A selinoid what??  Over my head on what this is.  I can't seem to run video clear enough to see much. Is a GAS engine then, not an electric???  I'm lost here.  Doesn't it scrare you to run fast and maybe think the thing could start tossing parts??  If it takes long time to get full rate, how can it be hooked up to items to run them?  Lost on that part too.  OK, I'll "Dumb" out of here....

That is very interesting.

If you've conquered perpetual motion, I want to buy 100,000 shares in your

company.

A solenoid engine is basically an electric solenoid that pulls on the crankshaft to spin a flywheel.

Technically it pulls on the connecting rod to operate, opposite to a gas engine that pushes on the connecting rod.

Other than that operation is basically the same as a gas engine.

 

Large versions of them were built in the 1880s trying to make enough torque to run industrial equipment.

They are horribly inefficient. This little monster draws over 10 amps at 12 volts to operate.

 

As for RPM, in the video it was only going 400+ RPM, last night I had it up to 1100 RPM with no failure.

I don't want to run it much faster tan that since I don't know what the flywheel(pulley) is rated for.

The pulley is of an injection pump for an old Gardner & Denver compressor

 

the bearings are good to around 3500 rpm.

The weakest part right now is the aluminum con rod. Its just a piece of 1/8 aluminum flat bar, with no bearing or bushing.

 

 

It actually runs very smooth.

The Microswitch that fires it is on an aluminum arm, and is operated by the counterweight on the eccentric.

I just ran it up to 700 and it was increasing at about 5 rpm per second, according to my cheapo digital contact tachometer.

That is slick.

I've never heard of a solenoid engine either.

So the micro switch kicking on and off acts the same  as the combustion cycle in a gas engine.

 

If you could drive a generator, it could produce its own electricity and run  indefinitely without any outside "fuel" source.

Unfortunately they are "Currently" too inefficient, too much loss from the mechanical parts. (friction etc.)

I would think a fan would be the best bet at actually getting some sort of work out of it.  I can't imagine it having the ability to do much if at all via a V-belt due to the friction load.  Cool thing to watch though.

You expand more energy than you create.  I don't think this would ever be possible.
