Usually I don't do much machining in the summer, but their was a lot of cold and rainy days this summer. So I did manage to build one engine. I saw this MESCO motor somewhere, maybe this site, and I thought it was an interesting design. The single lever controls both direction and speed. Later I found the patent for the original design. I scaled the diagram up to size on a photocopier and took all measurements from that.

Here is a early mock-up, I could of milled the whole frame out of one chunk but my wife hates that! :-X(noise) So I hacked it out from some 1/4" Ali plate.

Testing and working out the bugs.

In this picture you can see the cam and 2 "brushes". I used some brass for the first ones, but they wore away after a while. The new ones where made from some 0.010" freeler gauge material (Stainless?)

All polished-up and painted, ready for assembly. I used some VHT Caliper Enamel, It is very hard and resistant to most nasty motor stuff.

And of course the Video, I found out after I filmed this, it will self-reverse if I crank up the voltage a bit.

Great Build! I love these old electric engine designs. What kind of voltage are you powering it with?

Chuck
 
I am running 10-12v at 2 Amps. I think I will re-wind the coils with some thinner wire. The original MESCO ran off 1.5v

Very nice! Beautiful polish. Thanks for the post.
(I'd self reverse too if my voltage got cranked up. ;D)
 
I did an electric in a scotch yoke configuration using solenoids. Was also thinking about doing one as a beam configuration with two solenoids.

Mine was not a model of a real device like yours and no where near as nice of finish as yours has. Nice job!
 
That's very cool!

I hadn't seen one of these solenoid sorta engines before.

Best,

Wow, that is gorgeous! I love the black and gold! The flywheel looks great. Did you sandblast the spokes?

Very nicely done. The finish on it sure makes it stand out.

That's very nice! A pretty motor, and quiet too.
Good job, and looks like an interesting project.
What voltage is used? Do you know the minimum voltage it will run on?

Great job!!! Thanks for sharing. I've been interested in making one of those.
