Potentiometer is much smaller and cost less.
-
"not that necessary" so why would some people rather use motor speed control over pot?
-
Thats not necssisary, a potentiometer would be fine.
-
so it is induction motor? if so, the dimmer is not really good.. should have ac motor speed control. that way will work better.
-
NO.
-
is that an universal motor?
-
It does change gradual.

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.
