Sorry guys for using the list for something not really related to EMC, but I do know here are a lot of people with the knowledge I need.
It was long time ago I designed something with electronics, so I hope someone can help me. What I need is an electric braker-pusher. It will not need to come to an absolute stop, it should just add or release resistance on a rolling device. It's very much like the electric braker on a bicycle trainer, but with the option to give energy too. A little spec would be: A small motor, maybe 12 V and 30 W. Not sure how much needed yet. Should take a value, for example -100 to +100 from a computer, controlling the output. Minus values for braking and positive for pushing. Returns RPM from a magnet switch. The motor will always be rotated, even when braking at maximum, some kind of heat sink is definitely needed. I would say that the circuit is something like a servo controller board but a lot more primitive, no positioning or extras, just burning or giving energy. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
