Abstract
An intelligent air moving apparatus for cooling an electronics enclosure includes a motor for driving a fan at a variable rotational speed and a microcontroller for controlling the rotational speed of the motor. The microcontroller includes a speed sensor for sensing the rotational speed such that when the sensed rotational speed deviates below a target speed, the microcontroller detects a locked rotor condition.
