From the project

Matlab, Simulink, Hardware and C-code for a custom inverter project.

A low-voltage three-phase voltage source inverter designed from scratch to drive a BLDC/PMSM gimbal motor. The repo covers the whole path from motor model to spinning shaft: Simulink models, LTspice circuit simulation, KiCad PCB designs (three revisions), and STM32 firmware that generates sine-weighted PWM (SPWM) with the timer and DMA hardware instead of CPU interrupts.

Mosfets: common questions

How big is the Mosfets PCB?

The Mosfets measures 222.5 × 104.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Mosfets?

121 components, from 38 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Mosfets design files?

From the abd-alaj/BLDC-motor-custom-inverter repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Mosfets design in my own project?

The repository has no license, so all rights stay with abd-alaj. Use it as a reference, and ask the author before reusing the design.
