Hi all,
I am running a Maho MH900C which uses Inramat brushed servos driven by a 3TRM2, the motors have 3 power wires, looks like 1 neutral and 2 wires to the brushes, 4 brushes each with no inter-connection inside the motor.
Can I power these motors with AMC brush type servo drives or is there more to it than I can see.
Forgot to mention, I retrofitted the control 5 years ago to Linuxcnc and has run perfect until now.
Recently with no changes to the machine or control, the axis motion has deteriorated and the X and Y have quit completely and Z is very unstable.
I have checked for all the obvious; loose wires, blown fuses etc.
Has anyone re-powered these Indramat motors.

Thanks in advance for any advice.
