I have a plasma table here with a very old controller thats gonna get retrofitted with modern kit.
The Z axis is driven by this DC servo made by Smh (Moteurs et motoréducteurs, moteurs courant continu, motoréducteurs synchrones, moteurs pas-à-pas).
From the label, I can tell its a 24V DC, 3000rpm, 0.2nm. Label also says "PM" (permanent magnet?)
It has two plugs coming out of it, power and encoder I assume. Two wires on each, 4 total. Although I don't know if the two wires coming out the back are actually from a proper encoder because its labelled as a "tachometer". These two plugs are connected to a really ancient looking PCB with a cable that has 5 wires going back to the controller.
As the old controller is getting ripped out, I need to find a DC servo drive that can run this motor and take step/dir signals. I kinda have to use this motor because the Z axis frame is an aluminium casting shaped specifically for it. It's even rounded to fit the cylindrical shape fo the motor. It's also a non-standard frame size (apporx 32mm between bolts, 62mm motor diameter). My other option is buying a new motor and drive but that means replacing the Z Axis frame too so thats my last resort.
