Study of Phase Advance Angle Control (PAAC) Technique for Brushless DC (BLDC) Motor

The brushless DC (BLDC) motor is recognized by
the linear speed to voltage and torque to current respectively. It
possesses fast dynamic response and high power density with
high proportion of torque in spite of small size drive. However, it
is difficult for conventional BLDC motor drives where they
require wide range of operating speed. This is due to the torque
and speed response characteristics at high speed operating mode
in which deteriorated by the motor inductance components in
stator winding. Phase advance angle control (PAAC) technique is
used to control the phase current and improve torque and speed
responses in high speed operating mode. This paper discusses the
design of high-speed lossless BLDC motor using simulation
where the compatible phase advance motor drive is developed.
The results are then compared with laboratory proof for
validation.
