FAN CONTROL SYSTEM
First Claim
1. A fan control system, comprising:
- a first fan;
a second fan, which is adjacent to the first fan;
a first motor configured to rotate, which rotates the first fan;
a second motor configured to rotate, which rotates the second fan; and
a control unit configured to control rotational speeds of the first and second motors in order to control rotational speeds of the first and second fans, the control unit being further configuredto energize the first and second motors such that the rotational speeds of the first and second fans reach target rotational speeds prior to increasing the rotational speeds of the first and second fans to required rotational speeds, the target rotational speeds of the first and second fans being lower than those of the required rotational speeds of the first and second fans, andto energize the first and second motors such that the rotational speeds of the first and second fans reach the required rotational speeds after the rotational speeds of the first and second fans reach the target rotational speeds.

Abstract
A fan control system includes first and second adjacent fans, first and second motors configured to rotate the first and second fans, and a control unit configured to control rotational speeds of the first and second motors in order to control rotational speeds of the first and second fans. The first and second motors are energized such that the rotational speeds of the first and second fans reach target rotational speeds prior to increasing the rotational speeds of the first and second fans to required rotational speeds. The target rotational speeds are lower than the required rotational speeds. The first and second motors are energized such that the rotational speeds of the first and second fans reach the required rotational speeds after the rotational speeds of the first and second fans reach the target rotational speeds.
