Thanks for the help but it's a moot point now. We were using a 1/2 hp DC motor to reset a brush machine from the last hole to the first hole by advancing a 108 tooth ratchet wheel 8 teeth. After two motor failures and one controller failure, I give up on the idea. This type of machine comes from the factory with an air cylinder that rides the ratchet and has simple threaded rods with nuts to set the stroke limit. But, this assembly is $600, thus the DC motor set-up cost me $200...but a lot of grief and lost production. I traded another brush company some repair work on some machine parts for a used air cylinder set-up that only needed new threaded rods and some Stelite on the tooth picker. Oh well, so much for high-tech! The counter is now hooked-up to the limit switch that used to stop the DC motor, no problem.
I learned valuable lessons here: (But I don't WANT to learn valuable lessons anymore.)
