Key Points
BLDC controllers receive data
about the rotor position and
send pulses of current to the coil
windings to change their polarity in
the sequence required at the right
time.
BLDC controllers have an analog
front end and a digital back end.
They are categorized according to
how they estimate rotor position—
with or without sensors.
BLDC drivers provide the power
needed for each motor function.
These drivers are categorized by
the current switching approach they
use: trapezoidal, sinusoidal, or FOC.
