Motor Control, Part 4: Understanding Field-Oriented Control

Field-oriented control (FOC) is a technique used to control various motor types, including permanent magnet synchronous machines (PMSMs). FOC makes use of Clarke and Park transforms that convert the three-phase sinusoidal currents into the direct and quadrature currents. You’ll learn how the direct and quadrature currents are controlled to bring the stator field vector orthogonal to the rotor field vector to maximize the generated torque.
