Abstract:
Provided is a sensorless BLDC motor apparatus for providing a drive current allowing the rotor of the BLDC motor to be aligned in a predetermined direction during an initial position setting section (or for a first period of time), and providing a drive current allowing a frequency thereof to be varied at predetermined time intervals so as to accelerate the rotational speed of the BLDC motor during an open loop section (or for a second period of time), and a method using the same.
