http://archerycalculator.com/arrow-front-of-center-foc-calculator/ WebApr 8, 2015 · Field-oriented control (FOC) is more than just a set of vector equations; it is a treatise on how all AC motors fundamentally work. By its basic definition, FOC simply means controlling the orientation of a motor’s field (s) to achieve a desired result. From that definition, all motors do field-oriented control in one form or another.
