Solar motor with levitating rotor
Little by little a Mondocino motor develops - fascinating!

The first piece of the rotor is done. Later, the coil wire will be wound into the notches in the corners.
The solar panel is mono-crystalline and has a maximum current of approx. 200 mA at a voltage of approx. 0,5 V.
This translates into a maximum power of approx. 0,1 Watt.
The match shows the small dimensions of the motor.
Here you can see the completely glued rotor. The axle is made of Plexiglas, because I couldn't find round polycarbonate rods.
I glued a steel sphere (1,2 mm diameter) into the peak (right).
It is hardened and provides a long life expectancy with little wear and tear.
I put two R-10-04-05-N ring magnets on the front and the back of the rotor respectively.
I used a Q-40-20-05-N block magnet for a stator, which I embedded and glued into a Plexiglas plate.
On this picture you can see the dark wood inlaid work (marquetry) pretty well, which I used for aesthetic reasons.
I embedded a small wooden plate and a tiger's-eye on the side. This semi-precious stone constitutes the counter bearing to the steel sphere of the rotor. That's basically an inlaid work in the inlaid work.
The stone has a Mohs hardness of 6-7. So, it should last for a while when the rotor peak rests on it.
Here you can see the complete motor with all windings. Only now, when everything was done, did I glue the magnets to the mounting and the rotor.
The rotor really levitates in the magnetic field! I am pretty satisfied with this "debut work".
The next Mendocino motor will be out of wood. I have already something in mind that I want to try out.
