FORC Speed Controller

In Brief

FORC is a high-power ESC for field oriented control, designed in Altium and based on the Vedder ESC architecture. It was my first PCB project, taken from no experience at all to a finished board in 4 months.

Objective

Before starting this project, I had no experience in PCB design, at all. I had never touched a PCB software nor taken any advanced circuits courses. However, knowing how universal the applications of printed circuit boards are, I wanted to learn the process of how they are designed.

So, I designed FORC, my attempt at a high-power ESC specifically designed for Field Oriented Control. The software I used was Altium, which I chose over other beginner friendly choices like KiCad because it is more of an industry standard. My design is based on the Vedder ESC architecture, which is the gold standard for speed controllers in the application I am looking for.

The ultimate goal of FORC is to use it to drive my DIY OneWheel build, which is why it required specific components like an IMU and FSR sensor.
