115VAC low current fan speed controller Answered
I am fairly new to electronics, and have mostly worked with DC circuits so far. I have an AC fan I want to use to make a carbon filtered ventilation fan for my soldering station. I can do this with a DC circuit and DC fan, but when researching how to do it with an AC fan I came up with more questions than I started with...
The fan I have is a Nidec TA450AC model A30122-10. It is about 5x5x1.5 inches, and rated for 115VAC, 50/60Hz, .26/.21A. I found data on the fan here: http://http://www.nidecpg.com/fanpdfs/ta450ac.pdf
In my research so far it seems there might be three solutions: 1> Use a TRIAC/DIAC circuit, 2> Use a MOSFET circuit or 3> Use a microcontroller/PWM circuit. There seem to be benefits/drawbacks to each method, and I don't know which method to choose, or even if I'm headed in the right direction.. I don't know how to tell if the fan is single-phase, triple-phase, induction... ugh. I am looking for an inexpensive solution I can build myself, that performs well.
Can anyone help me find the right solution for my application? Or at least point me in the right direction?
