Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Has anyone taken the circuitry that is located on the F&P stator and used that to detect RPM's? How involved would that be? I still have both of the ones that were with my motors and would like to incorporate them into my system I am building. Expecially since it would make my testing go so much easier. Currently I am running the genny from an air compressor motor, but I only know the RPM's of the motor. I am not sure what the rpm's of the genny are with the pulleys I am using. I know though it is much faster then in a service condition. I had the genny putting out 586vac under no load, and through a transformer I had laying around, it was down to 68v or 34vac (centertapped UPS transformer).
BTW I have an old laptop at my disposal for this project, that maybe I could cable into that circuitry, but I an definatly not an electronics engineer.Edited by readyakira 2008-12-05

Don't you think Free/Renewable energy should be mandatory in new buildings?

The hall effects are apparently latching types. Optocouplers work a treat and are cheaper and simpler to impliment.
