Sirojudin Munir Releases a Clever STMicro STM32-Powered FOC Motor Driver under a Permissive License

Maker Sirojudin Munir has designed a new sensor or sensorless field-oriented control (FOC) driver for brushless DC (BLDC) motors — and made it available to all under a permissive license, hardware and firmware.

"I like building things from scratch," Munir explains by way of introduction to the project, "and this time I decided to make a new version of my BLDC FOC driver. This project started as a redesign of my previous motor driver, with improvements to the hardware, current sensing, firmware, and communication system. My previous FOC [driver] took many rounds of trial and error before it finally worked well. This time, I made a new version with a completely new design."

A field-oriented control (FOC) driver is designed to deliver smooth and precise control of a brushless DC motor with a high efficiency. Compared to a traditional control system, it works by aligning the stator's magnetic field orthogonal...
