Abstract

There are provided an apparatus and a method for controlling a fan motor. The apparatus for controlling a fan motor includes: a signal generating unit generating a pulse width modulation (PWM) input signal having a predetermined duty value; a memory storing duty correction values according to the duty value of the PWM input signal and driving characteristics of the fan motor therein; and a signal controlling unit generating a PWM output signal for operating the fan motor by using the PWM input signal and the duty correction values stored in the memory.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0005323 filed with the Korean Intellectual Property Office on Jan. 17, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an apparatus and method for controlling a fan motor, which can simplify circuits and reduce manufacturing costs by omitting separate external components such as resistors, and generate pulse width modulation (PWM) for controlling a fan motor from data stored in a memory. ) output signal to precisely regulate the operation of the fan motor. Background technique [0004] Typically, where the speed of a motor such as a fan motor can be controlled, the speed can be controlled by adjusting the duty cycle value of a pulse width modulated (PWM) signal. The duty ratio value of the PWM signal can be determined according to the time interval between the t...
