This Application Note describes the design of a low power 3-phase
BLDC (Brushless DC) motor drive with Hall Sensors, based on
Motorola's MC68HC908QY4 microcontroller.

BLDC motors are very popular in a wide application area. Compared
with a DC motor, the BLDC motor uses an electric commutator
(replacing the mechanical commutator), and so is more reliable than the
DC motor. In BLDC motors, rotor magnets generate the rotor's magnetic
flux so that they achieve higher efficiency. Therefore, BLDC motors may
be used in white goods, high-end pumps, fans and in other appliances
which require high reliability and efficiency.
