In this video, I share my experience experimenting with High Frequency Injection to obtain rotor position estimation without using any physical sensors on a motor. There are still many things that need improvement, especially in terms of reliability at higher torque. But I hope this experiment can be useful for those of you who are exploring motor control as well!
