Hey all,
just curious how some of you might go about trying to vary the speed of little cheap 24V DC Brushless fan.
I assume the built in electronics are trying to do some form of speed regulation and using some cheap form of feedback, so just dropping the voltage to 12V might actually just end up at the same speed (assuming back emf doesn't stall it).
Any insight into a low cost solution to vary a cheap little brushless fans speed?
I am accustomed to controlling the switching myself but am trying to think of the best way to do it with low cost fans.
Thanks in advance.
