Don’t forge, there are a couple of plugins/scripts around to help you draw the coils/loops. Some of them probably out of date, but a good starting point nonetheless.
There is the following utility
which can do the calculations for n-gon spiral inductors
[image]
and can export in kicad .mod format.
The guesstimated (using the equations for a circular coil) parameters for the above coil are:
Calculated inductance (Henries): 5.1530798890899644E-5
Calculated inductance (uH): 51.5308
Calculated self resonant frequency (Hz): 4457487
Calculated self resonant frequency (MHz): 4.4575
Enjoy responsibly.
This program creates coil footprints in KiCAD. You simply download the files, edit main.py with your desired parameters, then run the script to get the *.kicad_mod footprint file (drop into whatever KiCAD library you want) The program is hosted here...
Hi,
I’ve been working on a tool to automate the generation of PCB stators for electric motors.
The plugin is little more than a proof-of-concept a the moment, and the documentation still to be written.
But I’m looking forward to get feedback (suggestions, feature requests) from anyone out there interested on the topic.
I’m going to manufacture a test run and hope to get some pics to share soon.
Cheers,
Stefano
