README
README.mdMagnetorquer Optimization Tool
A tool for calculating the optimal trace width to maximize magnetic moment for PCB magnetorquer coils with various copper weights. This tool helps design optimal PCB-based magnetorquer coils by considering various constraints like trace width, spacing, current density, and power limitations.

Overview
This repository contains two different versions of the magnetorquer optimization tool:
magnetorquer_optimization.py- Command line version with basic functionalitymagnetorquer_optimize_with_graphics.py- GUI version with interactive graphs
Prerequisites
- Python 3.7+
- Required Python packages:
text numpy scipy matplotlib
Installation
-
Clone this repository:
bash git clone https://github.com/yourusername/magtorque-optimization.git cd magtorque-optimization -
Install required packages:
bash pip install numpy scipy matplotlib
Usage
Command Line Version
Run the basic optimization script: (I recommend using the graphical onen as this one is outdated)
python magnetorquer_optimization.pyYou'll be prompted to enter:
- Voltage supplied (V)
- Max power (W)
- Inner length (mm)
- Inner width (mm)
- Outer length (mm)
- Outer width (mm)
- Copper weight (oz) (USE 2.0 OZ)
- Number of layers (USE 6.0)
GUI Version
Run the graphical interface version:
python magnetorquer_optimize_with_graphics.pyThis provides an interactive interface where you can:
- Adjust parameters in real-time
- View optimization graphs
- See immediate results of parameter changes
Script Analysis
Working Scripts:
-
magnetorquer_optimization.py(Command Line Version)- Most reliable version
- Provides basic functionality
- Gives consistent results
-
magnetorquer_optimize_with_graphics.py(GUI Version)- Working visualization
- Includes real-time parameter updates
- Some unit conversion inconsistencies but functional
Known Limitations:
- All scripts assume uniform copper thickness
- Edge effects are not considered
- Thermal considerations are not included
- Magnetic field uniformity is not calculated
Parameter Guidelines
- Voltage:
- Power:
- Trace Width:
- Trace Spacing:
- Copper Weight:
- Number of Layers: Samwise - 6
Contributing
Feel free to open issues or submit pull requests. Areas that need improvement:
- Thermal analysis
- Edge effect calculations
- Better handling of non-square geometries
- Manufacturing constraint validation

Questions
How big is the ZPlus Panel PCB?
It measures 97 × 97.3 mm and has 4 copper layers, 1.61 mm thick.
What parts does the ZPlus Panel use?
37 parts, built around the HHM1589D1, CDBA240LL-G, SM101K07TF and SFH 2430-Z. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ZPlus Panel KiCad files?
From the Rivercraft911/magtorque-optimization repository on GitHub, at the commit this page was made from: the board is Temp/ZPlus_Panel.kicad_pcb and its schematic Temp/ZPlus_Panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZPlus Panel design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
