Introduction: 3D Printed Generator and How It Works.

By My Website
About: As a child, I grew up with Lego technic, model trains, computers and steam engines. As a young adult I started working in a small metal workshop in Austria. There I learned the knowledge of metalworking. When …

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.

Step 1:

Here you can see the assemblies.

Step 2:

Print the parts.

You can download all parts.

Step 3:

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.

Step 4:

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

Step 5:

The parts are assembled.

Step 6:

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

Step 7:

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

Step 8:

Performance test in my Emco Compact 5.

Step 9:

The generator can also be driven by means of gears.
