OK, on THIS thread I posted a completed project. Today I decided to add in an extra outlet to control a fan. It's working the way it's supposed to. BUT here's the problem: I have a shade pole motor fan for my work bench. I don't use it much because it's somewhat stronger than I care for. Knowing that this project can control an extra light or extra fan - I plugged this shade pole motor into it. When plugged into the fan port it will run at full power on high. But on low it stalls out and does nothing. Tried it on the "Light" circuit but there on High the fan spins up and down and up and down repeatedly, never attaining a full running speed. When the light is switched to low the motor stops all together. In either case it doesn't work. So I tried a regular 3 speed fan. The light circuit will run the fan when the light is on High. But when switched to Low the fan barely spins at all. It doesn't matter which speed I set the fan on (Low, Med or High on the column) when the light circuit is set to Low the fan barely spins. Obviously it has to do with what sort of motor I am using. That's where you guys come in:
The Light Circuit is controlled by two relays and a diode. It would seem that on high one relay applies full power to the lights. On Low the light circuit applies full voltage through a single diode (half wave clipped). I've plugged a light into the circuit and it does exactly what it's supposed to do - change the light from low to high and off. That's nice. But I don't want to control lights, I want to control a fan. So what kind of fan is recommended? The one that came out of the oven ? ? ? That's a pretty large squirrel cage fan and moves too much air, even on low. So I'm looking for options.
I'm waiting for a picture I took with my phone, sent via e-mail to my e-mail address. iPhone 11 takes a long time to send a picture. Will post when I get it.
