Advanced-Linear-Motor

An advanced design for linear motors. Uses also some advanced algorithms and Python scripts to optimize the copper usage, resistance, and heat dissipation.

Design goals

• 6 layer PCBs
• 70µm or 105µm thick copper
• Maximized copper packing for efficiency
• 3 phases
• 1 phase spans 2 layers
• Minimize the number of via

Adjustable Parameters

The following parameters can be adjusted to customize the design:

• number_of_tracks_per_pole: Defines the number of tracks within a single pole.
• clearance: Minimum spacing between tracks, in millimeters.

These parameters can be found and adjusted in the CONFIG section of the code.

PCB Parameters

• pcb_length_mm: Length of the PCB area dedicated to the tracks (in mm).
• pcb_height_mm: Height of the PCB area dedicated to the tracks (in mm).
• no_of_poles: Total number of poles in the design.
• no_of_periods: Number of repeating periods for the track layout.
• no_of_phases: Number of electrical phases (e.g., 3-phase motor).

Installation

1. Clone the repository:

   git clone <repository-url>

2. Place the plugin in KiCad's scripting plugins directory:
   • Windows: %APPDATA%/kicad/scripting/plugins/
   • Linux: ~/.local/share/kicad/scripting/plugins/
   • macOS: ~/Library/Application Support/kicad/scripting/plugins/
3. Restart KiCad to load the plugin.

Usage

1. Open your PCB project in KiCad.
2. Launch the plugin from Tools > External Plugins.
3. Adjust the design parameters as needed:
   • Track width, clearance, via dimensions
   • Number of poles and phases
4. Click Run Plugin to generate the layout.

Examples with Different Parameters

Example 1: Lower Number of Tracks

This example uses a lower value for number_of_tracks_per_pole. The clearance is kept at 0.25 mm.

Example 2: Higher Number of Tracks

This example increases the number_of_tracks_per_pole and the clearance is kept at 0.25 mm.
