Apparatus for DC motor of cooling fan

The present invention relates to direct current motor control device for the cooling fan to improve the PWM output voltage compensation speed, The cooling fan is a direct current motor control apparatus battery monitoring section that monitors a battery voltage; Motor output monitoring part that monitors the output voltage to the motor; After the reception, and the duty of the PWM signal based on the first adjustment to the battery voltage, a PWM signal having a duty predetermined transmitted from the ECU (Electric Control Unit), the duty of the PWM signal according to the motor output voltage secondary adjustment MCU (Micro Control Unit) that; And according to the duty of the PWM signal output from the MCU to convert the battery voltage to the PWM output voltage may include a gate driver that provides a direct current motor.
