A solenoid motor is a cross between an electric motor and an internal combustion engine, and the sound is closer to the second. In the first half of the nineteenth century, this design was seriously planned to be used to set mechanisms in motion. Now, on this principle, small mock-ups are being built, either working simply on their own, or, less commonly, rotating fan impellers. Especially those friends who in childhood read a book about Carlson, who remembered the accident described there, and who did not dare to build models of steam engines, Stirling engines and ICE. The author of Instructables under the nickname Dr Qui decided to make the solenoid motor, although without an impeller, but beautiful.
Beautiful - means, without a single extra hole in the stand. Therefore, the master performed debugging on a temporary stand made of plywood, and only having decided on the location of all components, he transferred them to a permanent one. It is pine, carved with a band saw and polished. On the reverse side, a recess for wires was made in it, filled with hot-melt adhesive along with them:
So the master performed the terminals for connecting the power source:
This flywheel was once part of the engine in a VCR. Everything has been removed from it, except, in fact, the flywheel and the shaft:
The crank is made of a flywheel from a CD drive and a screw from it:
Here they are individually:
To fix all this, Dr Qui slightly modified the aluminum corner:
And attached to it such a thing with a bearing from the same VCR engine:
For the beauty flywheel glued “pancake” from the hard drive with epoxy (see KDPV).
Rocker carved from aluminum:
In the central hole placed the bearing:
The rocker arm is welded using Durafix from several aluminum parts:
I drove it all a little on the aforementioned plywood stand with the first solenoid that came across from the telephone switch. Here, the “pancake” from the hard drive to the flywheel is not glued yet, and all mechanical connections have been made by hard wire. There is no contact group yet, so far you have to manually turn the solenoid on and off:
It turned out that the solenoid quickly overheats, and the method of transferring force from it to the beam is not optimal.The master looked for another solenoid in himself and found this:
Secured like this:
To transfer the force from the solenoid to the beam, he made an L-shaped link and a holder for it. Here again could not do without Durafix:
The transfer of effort with pieces of stiff wire is not serious. And here is more solid:
As a contact group, Dr Qui used a micro switch from a CD drive. An epoxy nut glued to it with a polymer insert, the stock was increased by the holder used in fountain pens for fastening them to the shirt:
So the master made a cam, pressing the rod at certain positions of the flywheel:
Connected the solenoid mechanically with the L-shaped link:
Connected terminals, micro switch and solenoid electrically:
Having decided on the location of the components, I transferred them from a temporary stand to a constant:
And he started the engine from a 12-volt battery used in the UPS:
Immediately after turning on the engine, the flywheel must be pushed, without which it will not start to rotate, and the solenoid will overheat.
