Questions
How big is the BLDC inverter PCB?
It measures 259.7 × 159.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BLDC inverter use?
104 parts, built around the IR2101PBF, LM2576HVT-12, LM393 and L7805. 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 BLDC inverter KiCad files?
From the vladBaciu/Sensorless-BLDC-HW repository on GitHub, at the commit this page was made from: the board is KICAD Workspace/Licenta_Vlad/BLDC inverter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLDC inverter design in my own project?
Its repository states no licence, so its author keeps all rights: ask vladBaciu before reusing the design.
