# KMotor_Pro

Current KiCad 9 GPL fork of KiMotor with deterministic PCB motor generation, extended stats, fabrication presets and a second magnet-PCB workflow.

Credits

• Original KiMotor concept and base implementation: Stefano Cottafavi
• Fork, UI overhaul, routing fixes, silkscreen/alignment helpers and ongoing development: I-T-C-R-W

Current Feature Set

• Radial coil generation remains the default stable path.
• Parallel, Radial and Compact coil style controls are available.
• maxSpec layout can switch dense / near-square slot setups to the compact workflow.
• Optional PCB / Wire winding mode for stats derivation.
• Fabrication presets for common JLCPCB and PCBWay setups.
• Generate Magnet PCB and Generate Both create a second board with shared mechanics.
• Corner alignment helpers generate NPTH hole arrays plus angular silkscreen scales.
• Terminal references and board info text are placed deterministically.
• Generated GND and mask zones are replaced without deleting unrelated board zones.

Physics / Stats

• Total, phase, coil and ring resistance
• Total copper length
• Turns per layer estimate
• Ke est, Kt est, Kv est
• Winding factor estimate
• No-load RPM @ 12V estimate
• Stall current and stall torque estimates

All higher-level motor values are currently shown explicitly as estimates.

Mechanical / Layout Improvements

• Safer geometry and intersection handling for vertical and near-vertical cases
• Deterministic slot anchor placement
• Deterministic center-via placement in the tested low-height edge cases
• Support TH / support via handling with collision checks
• KiCad 9 footprint directory detection via version-aware variables such as KICAD9_FOOTPRINT_DIR
• GUI layout cleanup and equalized column scaling
• Status panel with Ready, Running, Finished and Failed

Scope / Status

• 3P is the primary stable target
• 1P is improved and usable
• 3P+N still needs a final dedicated neutral-routing topology
• Compact is currently a stable workflow/UI mode; its dedicated final geometry solver is still being expanded

Next Steps

• predefined compact / maxSpec coil geometries
• further magnet-PCB production geometry
• richer derived motor stats
• later API-oriented deterministic engine extraction
