14mm Tiny Linear Stepper Motor

Post by JorgeP »

Here is a tiny linear stepper motor, most likely from a camera focus mechanism. These can be found online in bags of 10, 20, 50, etc. for faily cheap. There are 3 parts: The Case, the Shaft, and the Nut.

I learned how to extrude edges and round off (bevel) edges with this project. Does not have the flex PCB connector, Magnetics, or Coils. I just made it for visualizing the size of the motor for a scale model project out of paper I have been working on, you can guess what it is by the Photos below ("No Disassemble")!

The paper models, seen in the second photo, are 1:87 custom models based on MiniModel.cz 1:100 scale papercraft and will use these motors for steering, maybe also driving since I have 40+ left :) The Daimler Ferret is 100% custom and built from actual repair and service manuals.

I also attached the project file for the Motor.
