I thought I read somewhere that it is possible to drive a brushed dc servo motor with a brushless servo drive?
The servo motors are 140v SEM and right now are driven by Servo Dynamics 1525-10 drives on an old Anilam 3 axis mill.
This mill uses tachs on the motors for feedback.
The ones on the mill now are aging and starting to not hold position regardless of tuning.
I looked at AMC 25A20's. Which come brushed and brushless, but I can get the brushless cheaper and I need 3 of them.
Thanks for any help you can give.
