I don't think that small brushless motors (like fans) work good with this kind of dimmers, only brush motors like those inside drills, vacuum cleaners etc.
The reason is the starting coil (1-2 turns of thick copper wire around on both sides of the metal core of the stator), which after the triac switch-off sustains, for a short while, a big repelling magnetic force toward the rotor, braking it. It acts like a huge load, but since the short 'on' pulses from the dimmer, the motor may not overheat.
I know this motor is not made for a dimmer switch but I had a dimmer laying around and thought I would try it out. The corecct way would be to make a bendini motor controler.

is that an universal motor?

NO.

so it is induction motor? if so, the dimmer is not really good.. should have ac motor speed control. that way will work better.
wadamt16 2 years ago
Thats not necssisary, a potentiometer would be fine.
Electrotime 2 years ago
"not that necessary" so why would some people rather use motor speed control over pot?
wadamt16 2 years ago
Potentiometer is much smaller and cost less.

Is that an induction motor, similar to what a fan has? Was the change in speed jumpy, or gradual from low to high speed?

It does change gradual.

I tried to wire one...it only works barley...no power...why?

Did you conect the ground? Try a more expensive brand.

I tried one that was meant for a light. I used a 1.5 amp dimmer for a ceiling fan, and it worked ")

Glad to hear it worked.

hey electrotime can you put a dimmer on a 220v 3hp electric motor? How about a 120volt 2 how motor? I want to be able to control the rpms, thank you

220v might be a little high for a dimmer you might need a potentiometer.
Electrotime 3 years ago
yes or the motor wont slow down but with a light bulb it does

my motor slows down. does yours run off 120va?
Electrotime 4 years ago
I just use a fan that has a pure on off switch
woww1994 4 years ago
ok!!

i have to hook up a light bulb for mine so it works right
woww1994 4 years ago
a light bulb for what? [the dimmer switch]
