I made this some time ago, but it just always makes me smile and so ran it tonight and made a short video

Some more details of the solenoid v-twin are here along with some still images of the detailed design.
It doesn't generate much torque, but would be interesting to re-design as a more powerful motor
That would be a 2-stroke?
Hello Baja, this is actually a 4 stroke, the switches are driven from cams that are geared 2:1 from the crankshaft. Hopefully the image below helps:Quote:

Nice attention to detail.
I've finally managed to complete the plans for this motor/executive toy

A short video of this little model solenoid motor running

So simple to make and great fun if you're just wanting to get back into machining something
Sat watching my model solenoid motor on the desk and thought that this is a great example that shows the bearing fundamental train frequency, so had to video it in slow motion to share with you all.

Also, note that the switch is following the cam very closely with little bounce
Thought I would talk through how this strange little electric motor works:

I've been looking at improvements to the solenoid motor. The first thing I tried was magnetic confinement, I think you will agree this improves it.

I have a few more ideas on the list, but please do add more and I will see what I can do.
Sometimes people take your design and improve it. Henk Kaan used my plans for the solenoid motor and selected different materials to produce a sharper looking model.

This little machine is a great desktop toy and easy to make over a weekend, especially a rainy weekend.
I've been looking to make the solenoid motor powerful enough to drive a toy vehicle.
I've improved the stator of the solenoid by reducing gaps and wrapping the coil in a cast iron dust/swarf and epoxy mix. I increased the size of the armature magnets and overall have a 5x increase in force. More details: Solenoid Tractor - glue-it.com

Latest video of the motor running, just need to connect the crank to the wheels.

and now the tractor moves

Just to show that a solenoid motor can power something useful

what do you think?
A comparison between the sounds of a real Field Marshall and the solenoid powered model tractor

hope you like the inspiration I found in the sound
It is always a pleasure when someone takes your design and makes it better. Here Frits Kaan created a wooden version of the solenoid motor: https://www.glue-it.com/gallery/elec...motor-of-wood/

OK, there are some hidden bearings and a brass flywheel, it still looks very cool.
