Sanyo Denki steppers
« on: June 07, 2008, 11:11:20 AM »
I just got two Sanyo Denki steppers from an old IBM wide format line printer, Type 103-820-28 4.5V 1.4A 2 deg/step.

So how do I set these up, 2 deg/step so 180 per rev?

Thanks,

I tried looking up the motor spec online, however this monster of a printer is probably 28 years old so I found nothing useful aside from mounting dimensons, Had to figure out the leads with the ohmmeter.

There is a encoder disk with two concentric rings of slots, the opto switch (dual) and a plastic enclosure that may become a spindle speed sensor. I still have to gut the rest of it there is a huge powersupply with 3 big can capacitors and the transformer, so I guess I need to plug it in and see what voltages it puts out. Lot's more goodies in there too, I know I saw at least 3 or 4 microswitches.
