Sorry H500, Your well above my knowledge base when you start throwin them big words about! Thyristor???
As I stated in my original post the only H-bridge Designs I saw were for the low power robotics. Which is why I am posting.. to either find out that it is doable (without an engineering degree) or to find another cheaper easier way to do it. I am not set on an H-bridge design maybe a "simple thyristor circuit" is the way to build one. I was hoping all/some of the more experienced electronic people would give me a little direction.
Jroque
My design goals are: 1. Computer control
2. w/feedback
3. enough current/voltage for 2.5hp (that I aleady have, which is far in a way larger than the one you mentioned using)
4. A valuable learning tool
I will end up making a controler but the final design might be something other that my original connception..
I am inproccess now of diagraming the controller that runs this motor (the blown one). Also I may not have stated it but this motor/controller setup is from a commercial treadmill and not a Home unit. The two surpluss controlers are for home units, and home units are generally lighter duty.
thanks
