AN885, Brushless DC (BLDC) Motor Fundamentals

Compared to brushed DC motors and induction motors, BLDC motors have many advantages and few disadvantages. Brushless motors require less mainte-nance, so they have a longer life compared with brushed DC motors. BLDC motors produce more out-put power per frame size than brushed DC motors and induction motors. Because the rotor is made of perma-

Jan 05, 2010 · like DC values using standard control loops. Vector Control Summary The indirect vector control process can be summarized as follows: 1. The 3-phase stator currents are measured. These measurements provide values i a and i b. Ic is calculated by the following equation: ia + ib + ic = 0. 2. The 3-phase currents are converted to a two-axis system.
