Most members here whouldn't try to control the speed on that type of motor, becuase it's not easy to do, and attempting to do so can damage the motor. That's why you're not getting any response.
See, I didn't know that. It's helpful to know that something isn't easy.
By the way, this is a 20 year old Bodine Electric motor from a vibraphone, and there was an original control circuit.
Also, there's **broken link removed**.
I'm just surprised at the lack of responses I've been getting, ad this is my second thread. Last time I ended up figuring it out on my own; however now I'm trying to do something I really don't know how to do yet.
I believe the problem here is you are asking questions about an AC motor on an electronics forum. I have worked in the electronics industry for 35 years and know a lot of people who work in electronics. I would say very few of them have any idea of just how AC electric motors operate. Perhaps there is a forum somewhere that has more to do with AC electric motors.
