What Is Brushless Motor Vector Control?

Vector control and sine wave control are two brushless motor control methods. The core difference lies in the current control method. Vector control directly controls the vector current components in the parallel and perpendicular directions of the rotor magnetic field, eliminating the limitations of controller bandwidth and phase drift. Through mathematical calculation and reference coordinate conversion, precise control of the stator coil current and voltage is achieved, making the current quality independent of the motor speed. This control method simplifies the control process and improves system efficiency and performance.
