Sorry, I'm French and my english is not very good.

This instructable shows a demonstration of a single-phase asynchronous motor (induction motor).
I made some pieces with a metal lathe, but you can customize the implementation using a simple drill and recycled materials (metal, plastic, wood, cardboard).

Step 1: materials and tools

Some Duplo bricks (like Lego but slightly larger)
2 or 3 x relays (I use only the 12V coils)
1 x capacitor 4.7µF
1 x used bicycle dynamo (I need only the magnet)
1 x transformer 110 or 230V / 12V
Some pieces of metal (aluminum tube, brass rod)
A few pieces of plastic
A few pieces of epoxy copper plates for printed circuit boards (PCB)

Tools :
Drill (preferably drill press)
Possibly a little lathe
Saw, file, soldering iron, glue
<p>Ok, first of all I want to thank you for this instructable. It was very informative and I intend to make a version of this. I have a question if you could kindly clear up for me. Why the need for two coils? Your using AC in the coils and this in turn should create a changing (oscillating) magnetic field. Thus, this should induce a current in the cylinder using just one coil, right? So wouldn't just one coil work? Please explain.</p>
<p>Shaded pole motor :) you could do the same thing without capacitor and one coil and one aluminium plate between rotor and stator.</p>
C'est tr&egrave;s bien !
<p>very good for teaching kids thanks a lot</p>

Excellent, thanks!<br><br>And please don't ever apologise for your English &mdash; it's better than that of a LOT of English people!!
<p>Very cool, thanks for sharing!</p>
