HOW IT WORKS
This first iteration of the brushless motor led to many changes. Find out why we think 3D Printing is changing the world for the better.
The 3D printed parts to the brushless motor make a colorful collage! See for yourself what these parts represent.
Assembling all the 3D printed parts and electronics for the windpowerWriter.
We’re busy printing parts for the high school science project utilizing the 3D printed brushless motor. We believe 3D printing in education fosters creativity and independent thinking.
The winding tool is a 3D printed part that make the brushless motor assembly easier.

Find out how to select the magnets for the brushless motor.
A rotor with 2mm magnets was used in the testing.
The magnet is firmly fixed on the ground.
A permanent magnet is fixed on the lever above the coil.
Measuring, ranking and comparing the magnets before selecting.
Measure the basic characteristics of the motor by using it as a generator.
The goal of this project is 3D-printing a fully functional Wind Turbine at small scale.
The stator height is still 20mm in order to reuse the existing rotor with the 2mm magnets.
I’m using a scope to measure the RPM and the voltage.
The main housing needs to have space for a generator (same size as the 3d-printed brushless motor).
The first iteration of the brushless motor.
3D Printed Components of the wind turbine project.
Propeller shaft will have 5mm diameter and 2 ball bearings, and the generator is mounted coaxial with the propeller shaft.
The size of the objects is at the maximum of the build volume for an Ultimaker 2.
In the beginning I bought conductive and magnetic PLA from Proto Pasta.
3D Printed Brushless Motor consists of 4 main printed parts.
3D Printed Brushless Motor requires some additional non-printed pieces.
3D Printed Brushless Motor, Rotor: Use Magnets PETG or ABS.
3D Printed Brushless Motor, Motor Winding Tool - wires can be taped to the handle or tucked inside.
3D Printed Brushless Motor, Stator Winding Core.
Torque increases almost perfectly with the square of the speed.
Torque is more of a challenge, but with some physics, math, and a construction with a 20cm long lever and a scale measuring at a resolution of 0.1 g, it can be calculated.
All of the experiments performed to get familiar with conductive PLA.
I installed a hair dryer and heated it until the main block was feeling really hot.
The result when I was using the Makerbot Slicer with default PLA values and the magnetic PLA from Proto Pasta.
Finally, I reduced the temperature to 210° and I’m very satisfied with the final result.
The filament looked normal. It only had a small bulge between the cold and the hot part.
The cleaner box can be removed and added to a filament without unloading the filament from the extruder.
Aluminum foil was used for better contact.
The design is a single connected wire with various shapes.
It was quite a challenge to find good slicer settings for getting this printed.
While the result got better with each printing iteration, all of a sudden the magnetic PLA stopped printing.
