Document Type and Number:
Japanese Patent JP2021145530
Kind Code:
A
Abstract:
To provide a fan motor control device, an information processing device, and a fan motor control program that stably operate a system.SOLUTION: Fans 181-184 are rotated by their own motors. PWM controllers 231-234 transmit PWM signals to the fans 181-184, respectively, to rotate the fans 181-184. A PWM delay controller 260 delays the respective PWM signals transmitted from the PWM controllers 231-234 to the fans 181-184 based on the respective drive times of the fans 181-184 by the PWM signals.SELECTED DRAWING: Figure 2
