Good day everyone!

I have been searching her and on the web in general and am not having much luck.

Can anyone provide any help with finding spec sheets for the Yaskawa RM series servo motors. They have 4 brushes, they are from a 1985 Suwa robot.

I am confused as to what drive may have originally been used, and am curious if these motors can be driven with geckodrives? The 320 I believe?

Anyone have any thoughts?

pulling encoders to figure out line count etc..

Thanks for your time and consideration.
