rushless-dc (BLDC) motors have best-in-class
torque to weight ratio, high efficiency, and
effective control algorithms, which make
them effective solutions in applications
requiring high power density, such as cordless
power and garden tools, unmanned aerial vehicles
(UAV), robotics, and others. Improvements in semiconDigital

ductor packaging technology, motor control algorithms,
and power management integrated circuits (ICs) have
increased the industrial uptake of BLDC motors. Highpower
battery-powered motor-drive solutions require
power levels ranging from a few watts to hundreds or
even thousands of watts. High wattage systems require
high motor currents, resulting in design challenges of
system losses and thermal management. A system
designer's challenge is to accommodate all the functionalities
of a motor controller in a compact form for the
