I want to control the speed of a 230VAC fan motor like this:
I don’t really understand what circuits are appropiate for dimming lights and which ones are for motor speed (I don’t even know which circuits are for Synchronous or for Asynchronous motors)
I found several information about it on Google and I have found this options
Do you think this circuit is appropiate and could be adaptated to be controlled by arduino?
See the next schematich: http://arduino.cc/forum/index.php?action=dlattach;topic=91274.0;attach=14833
I saw the schematich in this post: http://arduino.cc/forum/index.php/topic,91274.15.html
In the post is said that this schematich could be adaptated to work with 230VA
Which option would be appropiate for a fan like that?
Thanks a lot
