Abstract
A system and method for controlling multiple cooling fans is presented. The circuitry for directly driving each of the motors is removed from the motor casings, thus increasing air flow and reducing replacement costs should a motor fail. The system includes a common processor for centrally controlling the speeds of the motors and monitoring the performance of each of the multiple motors.
