Brushed DC motors develop peak torque when stationary and increasing with the increase in velocity. This limitation is not there in case of brushless DC motor.
Brushless or BLDC motors, when compared to brushed motors, have high torque, high torque to weight ratio and increased efficiency. They also have very less electronic interference.
BLDC motors also don’t have any windings on the rotor so unlike brushed motors they do not have any relation with centrifugal forces. This makes them pretty standard used motor for specialist applications. They also consume very less power in comparison.
