Fans

Abstract: cooling , the speed of a brushless DC fan is controlled by varying the input DC voltage. Variable-speed fan , are controlled to the minimum level necessary for cooling. Since fan power consumption is , speed controlled by varying its input voltage and frequency. Beyond fan speed control, there are , DC motor driven fan, one way to improve efficiency is by using more complex three-phase electronic , fan reliabil ity. PWM heating is another source of motor losses, occurring when a DC fan is operated
