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. WebThe generated motor torque here is calculated offline through the measured phase current and the motor angle.
