PWM control remains a popular method of fan speed control for a number of reasons. One reason is that motors, DC motors in particular, are very responsive to PWM. They adjust their speed with little lag time after receiving a PWM signal. Another factor is that PWM signals themselves are very fast, especially when few or no computations are required.
PWM is the best and easy way to control speed of DC Motors. PIC Microcontroller L293D. In this tutorial we will see how to control the speed of a DC Motor using Pulse Width Modulation (PWM). My question is should I use two L293 IC for 2 motors? both joints moves up and down wards. not side...
Teoretically is possible to use 4-wire fan like 3-wire on the board with 3-wire connector. Vice-versa it is possible to use old 3-wire fan on new board with 4-wire header, but with limited possibility of PWM control depending on board logic. Update October 13 2008. Fan uses control IC BD6709NFS from Rohm company.
