Abstract: A method for controlling a brushless direct current (BLDC) motor is disclosed. The method includes: receiving a constant current; comparing the constant current to a reference current; based on the comparison revealing that the constant current is smaller than the reference current, providing a first speed command to the rotational speed control unit to increase a speed of the BLDC motor; based on the comparison revealing that the constant current is larger than the reference current, providing a second speed command to the rotational speed control unit to decrease a speed of the BLDC motor; based on the comparison revealing that the constant current is the same as the reference current, providing a third speed command to the rotational speed control unit to maintain a speed of the BLDC motor; and controlling, by the rotational speed control unit, a speed of the BLDC motor.
