Designing an ESC for my PCB Motor

Оригинал видео: Все права на это видео принадлежат автору канала: This video shows how i designed my PCB Motor’s ESC and what where the challenges involved in getting my speed controller to work. It has a PIC16F1503 as the main controller and a triple half bridge driver STSPIN230, to control the three phases of the motor. These are both powered from the same supply, to avoid having an extra power wire or on-board regulator, reducing the cost even further. I filtered the digital circuitry supply from an LC filter to attenuate any noise the motor can generate. It can operate from a 5V to supply and draws around 220mA in total. The back emf generated from my pcb motor was too weak to implemented a sensorless speed controller. So i decided to use a hall sensor to provide feedback to the microcontroller which handles the closed loop speed controller. In the beginning of November I will be giving a demo of this project at the Hackaday Superconference so see you there!
