The construction of this small motor is straightforward. I used brass wire for the rotor and PVC for the frame, although any non-magnetic material would be suitable.

For the rotor, I formed a simple structure from brass wire and soldered two 67.5 × 34.5 mm solar panels mounted in opposite directions. I then attached the two solenoids (see component list) using hot glue and connected each coil to its corresponding panel. The two assemblies are identical.

At the top of the rotor, I fixed (with superglue) a small iron screw, which serves as the magnetic suspension point.

The stator consists of a frame with a magnet positioned at the top to suspend the rotor, and a second magnet placed laterally to generate the static magnetic field that interacts with the coils.

NOTE: This is still a prototype and leaves room for improvement. For instance, the solar panels could be tilted to better align with the direction of incoming sunlight, increasing efficiency. In addition, a more precise and refined construction would improve both performance and overall appearance.
