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-

BLDC motor control with Hall sensor based on FRDM-KE02Z

Replacing a DC motor with a BLDC motor places higher demands on a control algorithm and a control circuit. • First, the BLDC motor is usually a three-phase system; so, it has to be powered by a three-phase power supply. • Second, the rotor position must be known at certain angles in order to align the applied voltage.
