A BLDC motor phase commutation method is provided, which can correctly detect phase commutation timing and position detection timing of a BLDC motor in a compressor to stabilize rotation and RPM of the compressor, thereby minimizing noise and vibration. When the BLDC motor rotates through a mechanical angle corresponding to one period, the BLDC motor operates according to a first scheme in which operation of the BLDC motor in the first phase commutation section of a period is performed in the same manner as in the last phase commutation section of a period immediately prior to the period. After the BLDC motor switches to sensorless mode, the BLDC motor operates according to a third scheme in which the first phase commutation section of a period has a time interval equal to the average of time intervals of first phase commutation sections of periods prior to the period.
A Brushless Direct Current (BLDC) motor phase commutation method comprising, when a BLDC motor performs phase commutation after rotating through a mechanical angle corresponding to a first period, controlling operation of the BLDC motor in a phase commutation section of a period next to the first period to be performed in a same manner as in a first phase commutation section of the first period.
A Brushless Direct Current (BLDC) motor phase commutation method comprising, when a BLDC motor rotates through a mechanical angle corresponding to one period, setting a time interval of a first phase commutation section of the period to be equal to an average of time intervals of first phase commutation sections of periods prior to the period.
