Overview
Winding BLDC hub motors by hand is slow and inconsistent. This machine automates the whole process: it winds the motor hub with real-time 3-axis stepper control and sequences each winding pattern from a programmable G-code file.
What I built
- Real-time motion control using quadrature encoder feedback.
- Custom G-code interpreter for programmable winding sequences, which also runs the calibration sequence for multiple motor hubs.
- Self-calibration logic that detects the motor hub slots automatically.
- Smooth acceleration and deceleration profiles for precise winding control.
- Touch interface and IoT support for remote monitoring.
- Complete mechanical design, hardware integration and firmware, end to end.
