I tried an AC light dimmer (rated for 800W) on a 250W air blower used for inflating medium sized inflatables. It seems to do the job of controlling the speed.
But I've been told by some that doing that to a brushless AC motor will burn it. Then some say otherwise so I'm not sure what to think.
There are similar "dimmers" on eBay that claim they can control fan motors speeds as well but I'm not sure whether to trust these chinese item descriptions or not. https://www.ebay.com/sch/i.html?_fr...rol.TRS0&_nkw=ac+motor+speed+control&_sacat=0
I'm disassembled the motor case and there are three cables coming out of it, two are connected to each other and to a large capacitor (maybe for kickstarting the motor?) and there's one neutral wire.
So what's the case? Can I use these off-the-shelf dimmers for control the intensity of my blower or am I at risk of damaging it?
A side question, mine is meant for 220V AC, if we use it in the US will it just blow slower or is again at risk of getting damaged?
