ABSTRACT:
A fan motor control device comprises a clock signal generator and a drive unit. The clock signal generator generates a low-frequency clock signal. A frequency of low-frequency clock signal is less than 23 KHz. The drive unit converts the low-frequency clock signal to a high-frequency drive signal and outputs the high-frequency drive signal to drive the fan motor. A frequency of the high-frequency drive signal is higher than 23 KHz.
