Field oriented control. Feb 19, 2025 · Field Oriented Control (FOC), also known as vector control, is an advanced motor control technique used for AC motors like permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC). Field-oriented control (FOC), sometimes called vector control, benefits both accuracy and efficiency. Current is sensed on the motor leads. This document explains the principles, algorithms and implementation of FOC, as well as the advantages of digital and analog methods. 2 Field oriented control algorithm’s main task is to take user defined voltage uq and, by continuously reading the position of the motor rotor a, calculate the appropriate phase voltages ua, ub and uc. It is the most efficient way to control permanent magnet synchronous motors such as 3-phase BLDC motors or 2-phase stepper motors. The electrical drive controls become more accurate in the sense that not only are the DC quantities controlled but also the three phase AC currents and voltages are managed by so-called vector controls. Apr 20, 2023 · Field oriented control is optimum to maximize torque Stator winding currents and consequent field intensity and direction can be represented as three rotating vectors 120 degrees apart, in a common static frame. FOC uses orthogonal applied current to drive electrical motors. com Learn how to use the Field Orientated Control (FOC) scheme to achieve accurate and efficient vector control of AC motors. na yzx2 6ikpuc 20tq41 vmvp bb dvb3bo 7j md7 bkjh5j
