Frequently Asked Questions
Winding Machine
Is CAD data for this project available?
No, the CAD data for this project is not open source. For more context, read our blog post: Why Open Source Hardware Is Hard
Why not NEMA stepper motors?
NEMA steppers could be used. We use BLDC motors just because we build them.
Why closed loop control?
Closed-loop control is absolutely critical. If an open-loop stepper misses even one step (e.g., due to load, acceleration, or external force), the entire winding pattern gets messed up. Closed-loop ensures the motor always knows its exact position, correcting for any missed steps or external disturbances.
