Hi all,
I have a 220V AC geared synchronous motor like the ones used in microwave ovens : http://cgi.ebay.fr/Moteur-synchrone...ge_ElectroniqueComposants&hash=item56381ac12d
The seller's spec says its rotation direction can be set depending on the half wave sign of the AC voltage at switch-on. I've browsed a lot of documentations on this type of motor but can't find if it's true.
I want to know if with a triac controlled by an ATTiny45 (that I already use to slow the speed of my laminator), I can reliably control the rotation direction since with a uP, I can easily control the sign of the voltage. It will be used to raise and lower a small flag.
If anyone with some experience on this kind a particular use of such motor can share his knowledge, I'd be interested to know.
Many thanks in advance!
