    摘要: A method of controlling the speed of a BLDC (brushless direct current) motor and a method of controlling the cooling speed of a refrigerator using the same. A method of controlling the speed of a BLDC motor includes: inputting a driving signal having a predetermined reference current applying angle to the motor to achieve a predetermined reference speed; measuring a rotating speed of the motor; increasing a current applying angle of the driving signal if the measured rotating speed does not reach the reference speed and the driving signal has reached a maximum input of the motor; and inputting the driving signal having the increased current applying angle to the BLDC motor.
