Well, I believe I have a good conclusion to this issue. I am using voltage control. I took an old computer power supply box and removed the guts except for the little cooling fan. I then put in an autotransformer (from a broken stereo amplifier) which had a 65v and a 15v tap. I installed a...
OK, BradtheRad #7, I have tried what you did, namely reducing the voltage using a transformer. It works great. I ran it for an hour or so and everything seems OK. Today I picked up a light dimmer at a thrift store and I'd like to try that, too. I admit to being a little edgy about doing...
That's exciting. Can I plug my fan directly into this circuit even though the fan unit has its own internal speed control? At this point I do not know what the nature of it's internal speed control is.
BradtheRad #7... You addressed a question I was wondering about, namely reducing the AC voltage at the plug. This would prevent the need for invasive intervention. So I gather that at half voltage there is still enough magnetism for the motor to function happily. Also I gather that speed can...
OK. Regarding the noise... this is a new fan. The noise is merely the whirring sound of the air being blown. I want to use this blower to blow cooled air into our bedroom at night for sleeping, so I want to keep any noise, even whirring, to a minimum. Since the CFM is greater than necessary...
So this circuit, which is only slightly different from the first one I sited, says that it is for induction motors. Would it be a good one for my application...
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...
