The old DC servos are the Gould 12.5 amp stall 90 VDC motors. We have been trying to equate the motor ratings into a Horsepower or KW rating for cross reference purposes to an AC servo motor. What we have come up with so far is that we should need 750 watt AC Servo motors and drivers. We have checked the various torque ratings and they look good.
Can someone offer some advise on selecting suitable AC servo motors?
Thanks
