I have a 120VAC AC blower... it's a Lasko type FB Model 655704. The spec says ... motor TP 1.0 amp. It has 3 speeds. But even the slowest speed is faster and noisier than I'd like. So I would like to build a simple Triac speed controller for it. For my application, I don't think I need be concerned about RF interference.
I'm looking at this design... https://electronics-diy.com/1000w-ac-motor-speed-controller.php
Here are my questions:
1. Does my blower have a universal type motor with brushes?
2. Is the circuit sited above a good circuit to use?
3. For the 500K pot, is a simple basic 1/4W one OK?
4. This circuit doesn't give spec for the diac and triac. Below is another similar circuit which does specify these, but it says it's for an induction motor. Can I use these (D3202U, and T27008) for my circuit?
