Abstract: A Brushless Direct Current (BLDC) motor starting method and device are provided. With the method and/or device, startup noise and vibration and startup failure rate can be reduced using a constant low-speed startup scheme when the BLDC motor is in startup mode. Additionally, Pulse Width Modulation (PWM) duty is also maintained at low level when the BLDC motor starts up, thereby preventing excessive current from occurring due to desynchronization of the motor at startup, so that it is possible to optimize specifications of an inverter in the BLDC motor. The BLDC motor starts up with a synchronous speed and a PWM duty of a rotor of the BLDC motor being kept constant, and the BLDC motor switches to sensorless mode if a position of the rotor is detected a predetermined number of times or more during a specific time period.

Abstract: 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.
