I have a couple of servos I'd like to use for something. The problem with them is that they're older DC servos and the nameplates are long gone - they've been repainted and/or cleaned away.
I can work out the Kv and Kt parameters by testing, but I still won't know the max voltage and other specs.
So, I'm hoping someone here recognizes them.
They're 4 brush motors about 5 inches in diameter and 17 or so long with a tachometer and BEI encoder attached under the rear cap. I'm going to guess they are maybe vintage 1985-1990?
The one identifying mark they had was an old sticker with "Dynex" on it. The phone number matches Dynex Industries Inc, a defunct (or mostly so) company that did electrical service work, so I'm thinking they serviced this motor rather than manufactured it.
Thanks for any info (even brand) that anyone can supply.
Pics are attached.
