Hi All.
It’s often said that you shouldn’t use a light dimmer to control motors; it causes hum and stress.
But I’m wondering if it’s OK to do the opposite. I’m going to ‘steal’ some power for a ceiling fan from a circuit with two incandescent lights. Can I put the motor controller upstream of all three devices?
Thanks,
Scott.

Reasonably sure it would be OK, so long as wattage limits are observed.
Thanks; that's what I figured, but it's always good to bounce it off someone....Scott.Always remember those first immortal words that Adam said to Eve, “You’d better stand back, I don’t know how big this thing’s going to get.â€
Scott,
The speed control for the Hunter "Old Tyme" ceiling fans, the fans that weigh like 40lbs and have that direct drive ring motor, only allow for a limited amount of slowing down the fan. I've found that the slower the fan was adjusted the louder the hum got.
If you are dimming two lights and the fan, and with the correct speed control for that fan at your wall switch, your lights won't dim down as low as you may prefer. Using a standard dimmer my cost you your fan motor due to low voltage and heat buildup.

Ok, thanks for that. Dimming the lights really low isn't a concern. We rarely use them and may even remove them; I'm far more concerned about the fan which we need to distribute heat from a wood stove.Cheers,Scott.Always remember those first immortal words that Adam said to Eve, “You’d better stand back, I don’t know how big this thing’s going to get.â€
