Hi guys.
I'd like to ask some people here if they have ever heard or encountered this problem of mine..It is somewhat strange and very odd to me.
Task OT:
Building EDM-Wirecut machine. Bought an old wirecut machine structure with some parts on it for salvage to retrofit. Included is diagrams.
Problem:
There are X and Y axis servo motors which seem very strange to me. They have 9pins... How do I identify this type of stepper motor? There is no label no current rating. Absolutely nothing written on it. I would love to use these babies since they are already perfectly fitted into the system and me only needing to make or purchase a driver circuit for it to attach to an Old computer with LPT port.
My biggest problem here is where to begin with this 9 wire setup. Like knowing what phase angle it will produce in unipolar mode and what stepper driver card I should buy for this stepper motor?
Below I have included some images.
In case it is hard to read there are 9 pins.
Ohmic readings are 18 ohms and 9 ohms.
There is 1 common which is pin 5 which connects to 1 side of the winding.
For example pin 2-3,2-4,2-6,2-7,2-8,2-9 is 18 ohms except pin 2-5 which is 9 ohms.
Best Regards Franz
