3D Printed Generator and How It Works.

In this video I build a 3D printed generator. It is driven by a gear ratio by hand. There are 8 pieces of magnets with a diameter of 15mm. The centric wave has a diameter of 12mm and is ~ 90mm long. For the 6 pieces of copper coils I used a 0.5mm painted copper wire. It is needed ~ 50m wire. The rotor has a diameter of 95mm. All parts were printed from PLA.In the video I used a much too strong lamp. As a result, the efficiency is relatively low. This should actually be slightly higher.

Here you can see the assemblies.


Print the parts.
You can download all parts.





The coil holders are mounted. These are wound with 0.5mm copper wire and pressed into the stator.
They are fixed by means of adhesive tape.


The magnets must be mounted alternately. The opposing magnets attract each other.



The parts are assembled.



An alternating magnetic field is generated which moves the electrons back and forth. This generates an alternating voltage.



This 3 phase AC voltage must be converted to DC. This is done with a simple circuit. Only 6 diodes are needed.



Performance test in my Emco Compact 5.


The generator can also be driven by means of gears.
