Not sure if that's what you call it. Maybe you can just tell me the name for the type of control so I can search to learn more about it if you don't have time to read all this and help me understand it. My electronics teacher should know but I don't want to rely on him for my own project I'm presenting... This my first year in 10th grade H.S. and we have to come up with something before the end of the semester that we come up with to make use of basic electronics. Well my idea isn't so basic. I want to take a 120 volt 1.5 amp motor and cause it to run in a pulse pattern. In other words, it switches on for a second or two, just long enough to get it turning, then off for the same time frame (adjustable?) and back on the same way over and over. I want this to be readily capable of pluging in-line to where I could add it to anything I wanted temporarily.
What I hope to accomplish is a very very low speed for a fan for the sake of non-intrusive room aerating with a window fan, while also having the ability to switch it off, or bypass it to use normal settings.
I wonder if this will damage the fan... perhaps shorten the life of the coil wire or brushes if there are any... and overhead after a while because of the extra amperage that would be encouraged to push it at repeated start-ups... well;. that's what testing and finding out will show.
Can someone just tell me the name for this kind of circuit? And maybe give me a hint as to what general components will accomplish this?
Thanks so much.
