3D Printed Axial Flux Stepper Motor

This is my axial flux stepper motor. It’s called an axial flux motor because the magnetic fields line are oriented in the direction of the axis of rotation unlike a regular stepper motor where the magnetic fields line are oriented radially towards the center.

You also may have heard it referred to as a pancake motor. One of the major advantages of these motors is the ability to have multiple rotors and stators stacked together like pancakes. This results in a very strong and relatively compact motor. They are often used in heavy machinery and in applications where space is a limited resource.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
